Key Takeaways

  • Refinancing replaces your current mortgage with a brand-new loan and a single monthly payment. Second mortgages, on the other hand, add a new loan payment while keeping your original mortgage in place.
  • According to research from the Federal Reserve Bank of New York on mortgage lending risk, second mortgages usually have interest rates that are 0.50 to 1.50 percentage points higher than refinance rates as of December 2025. This is because second liens are more likely to lead to foreclosure for lenders.
  • The Consumer Financial Protection Bureau says that closing costs for refinancing usually range from 2% to 6% of the loan amount ($6,000 to $18,000 on a $300,000 loan). Home equity loans, on the other hand, usually cover most or all of the closing costs, which could save you $3,000 to $5,000 up front.
  • Homeowners who refinanced in 2020 or 2021 at rates below 3.50% should strongly consider getting a second mortgage instead of cash-out refinancing in 2026. This will help them avoid going from very low rates to the current average of 6.18%, which Freddie Mac says is the current average.
  • Cash-out refinancing is best for people who can keep or lower their interest rate while getting equity. This is especially true for people who have mortgages with rates of 6.75% or higher from 2022 to 2023.
  • Bankrate's national rate surveys say that as of late 2025, home equity loans offer fixed-rate lump sum payments of 8.50 to 9.50%. HELOCs, on the other hand, offer variable rates starting at 8.75 to 10.00% and allow you to use your credit again and again.
  • Fannie Mae and Freddie Mac say that the highest loan-to-value ratio for cash-out refinancing on primary residences is usually 80%. This means that you must keep at least 20% equity. For second mortgages, however, the combined loan-to-value ratio can be as high as 90%, depending on credit scores and lender requirements.

Okay, so here's what happened. You're sitting at your kitchen table in 2026 looking at home equity statements showing you've built $120,000 in equity over the past five years. Your roof needs replacing at $18,000, your HVAC system died last week requiring another $12,000, and your daughter's college tuition bill arrived this morning for $25,000. You need approximately $55,000, but you're not sure whether to refinance your existing mortgage or take out a second mortgage against your equity.

The distinction matters significantly because your choice affects your monthly payment, total interest costs, and financial flexibility for years to come. Refinancing replaces your current mortgage entirely with a new loan, giving you one payment but potentially changing your interest rate dramatically. A second mortgage leaves your original loan untouched while adding a separate loan and payment secured by your remaining equity.

Think of it like this: refinancing is like trading in your car for a new one with different terms, while a second mortgage is like taking out a separate auto loan for a boat while keeping your original car loan exactly as it is. Both accomplish the goal of borrowing money, but they work through completely different mechanisms with distinct advantages and disadvantages.

This comprehensive guide examines seven critical differences between second mortgages and refinancing in 2026's current market environment. You'll discover how interest rates compare between these options, when each choice makes financial sense, cost analysis with worked calculations, qualification requirements, and strategic considerations for homeowners who refinanced during the 2020-2021 ultra-low rate period.

1. Fundamental Structure: One Loan Versus Two Loans

The primary structural difference between second mortgages and refinancing centers on how many loans you maintain after the transaction completes. This distinction affects everything from monthly payment management to foreclosure risk to future refinancing flexibility.

When you refinance your mortgage, you completely pay off and terminate your existing loan by replacing it with a new mortgage. The new loan pays your old lender the remaining balance, and you start fresh with updated terms including a new interest rate, potentially different loan amount, and reset amortization schedule. Your monthly payment obligation consolidates into this single new loan.

Consider a concrete example using current 2026 market conditions. Suppose you purchased your home in 2019 with a $280,000 mortgage at 3.875%. As of early 2026, you've paid the balance down to $245,000. Your current monthly principal and interest payment is $1,316.

If you execute a cash-out refinance for $300,000 at today's average 6.18% rate according to Freddie Mac's December 24, 2025 Primary Mortgage Market Survey, you'd receive approximately $55,000 cash after paying off the old loan. However, your new monthly payment becomes $1,825, an increase of $509 monthly or $6,108 annually.

Second mortgages work entirely differently. Your original $245,000 mortgage at 3.875% remains completely intact with its $1,316 monthly payment unchanged. You add a separate loan secured by your remaining home equity. If you take a $55,000 home equity loan at 8.75% (a typical current rate as of December 2025 according to Bankrate's home equity loan rate survey), you'd add approximately $436 monthly to your payment for a 10-year term.

Your total monthly obligation becomes $1,752 ($1,316 original mortgage plus $436 home equity loan), slightly less than the refinanced payment of $1,825. More importantly, the home equity loan payment is temporary, ending after 10 years, while the refinanced mortgage payment continues for the full 30-year term.

The Federal Reserve Bank of New York's Quarterly Report on Household Debt and Credit for Q1 2025 (released May 2025) reports that second mortgage originations increased 22% year-over-year, suggesting many homeowners prefer maintaining their existing low-rate mortgages rather than refinancing to higher current rates.

2. Interest Rate Differences and Lender Risk Assessment

Interest rates on second mortgages consistently exceed rates on refinanced first mortgages, a difference driven by lien position and foreclosure risk rather than arbitrary lender preferences. Understanding why this spread exists helps you evaluate the true cost of each option.

Mortgage lenders assess risk based primarily on lien position, the legal order determining which creditor gets paid first if foreclosure occurs according to the Consumer Financial Protection Bureau's guidance on mortgages. First mortgages, whether original purchases or refinances, hold first lien position. If the home sells at foreclosure, the first mortgage lender receives full payment before any other creditors receive anything. This priority position reduces lender risk significantly.

Second mortgages occupy second lien position, meaning they only get paid after the first mortgage is fully satisfied. If home values decline or foreclosure sale prices disappoint, second mortgage lenders face substantially higher risk of receiving partial payment or nothing at all. This elevated risk translates directly into higher interest rates.

As of late December 2025, current market rates demonstrate this spread clearly. Freddie Mac reports 30-year fixed-rate mortgages averaging 6.18%. Bankrate's survey of home equity loan rates shows averages between 8.50 and 9.50%, a spread of approximately 2.32 to 3.32 percentage points above first mortgage rates. HELOCs show similar or slightly higher rates, with variable starting rates around 8.75 to 10.00% depending on credit scores and lender terms.

The cost implications become clear through calculations. On a $55,000 loan amount, at 6.18% (cash-out refinance rate included in new first mortgage) over 30 years, you'd pay approximately $66,585 in interest for a total repayment of $121,585. At 8.75% (home equity loan rate) over 10 years you'd pay approximately $23,265 in interest for a total repayment of $78,265. At 9.25% (higher-end home equity loan rate) over 10 years you'd pay approximately $24,885 in interest for a total repayment of $79,885.

The refinance appears dramatically cheaper at $66,585 total interest versus $23,265 for the home equity loan. However, this comparison misleads because it ignores what happens to your existing mortgage. If you currently have a 3.875% rate and refinance everything to 6.18%, you're paying significantly more interest on the original $245,000 balance, not just the new $55,000 you're borrowing.

A more accurate comparison isolates the marginal cost of accessing the $55,000. Scenario 1 with cash-out refinance to $300,000 at 6.18% gives you a new monthly payment of $1,825, total paid over 30 years of $657,000, and total interest paid of $357,000. Scenario 2 keeping your existing $245,000 mortgage at 3.875% and adding a $55,000 home equity loan at 8.75% for 10 years gives you an original mortgage payment of $1,316 continuing for the remaining term, a home equity loan payment of $436 for 10 years only, combined payment years 1-10 of $1,752, and after year 10 only $1,316.

When you perform the full 30-year analysis, the second mortgage approach saves substantial money despite the higher interest rate on the $55,000 portion. You're preserving the ultra-low 3.875% rate on the larger $245,000 balance rather than increasing it to 6.18%.

3. Closing Costs and Upfront Expenses

The upfront cost difference between refinancing and second mortgages often determines which option homeowners choose, particularly when immediate cash flow matters more than long-term interest optimization. Refinancing typically involves significantly higher closing costs that can reach thousands of dollars, while many home equity loan providers cover most or all fees.

Cash-out refinancing closing costs generally range from 2 to 6% of the total new loan amount according to the Consumer Financial Protection Bureau's refinancing guidance updated August 2025. This includes appraisal fees ($400 to $600), origination fees (0.50 to 1.50% of loan amount), title search and insurance ($700 to $1,500), credit report fees ($30 to $50), and various processing and underwriting charges.

On a $300,000 cash-out refinance, you'd typically pay $6,000 in closing costs in a 2% scenario, $12,000 in a 4% scenario, and $18,000 in a 6% scenario. The 4% middle estimate ($12,000) represents the most common experience. You can sometimes roll these costs into your loan balance, but doing so increases your principal and therefore your monthly payment and total interest paid over the loan's life.

Home equity loans and HELOCs often involve dramatically lower upfront costs. Many lenders in 2026's competitive market advertise no closing cost home equity loans where the lender covers appraisal fees, title work, and origination charges. While some lenders offset this by charging slightly higher interest rates (typically 0.25 to 0.50 percentage points), the upfront savings remain substantial.

When closing costs do apply to second mortgages, they typically range from $500 to $3,000 total, approximately one-quarter to one-half of refinancing costs on comparable loan amounts. Lenders' willingness to absorb costs reflects their desire to capture second lien business in a market where refinancing volumes have declined due to the rate lock-in effect affecting homeowners with mortgages below 4.00%.

The upfront cost advantage becomes particularly important in several scenarios. If you need funds for an immediate expense like emergency home repairs or medical bills, paying $12,000 in refinancing costs significantly reduces the net proceeds you receive. On a $55,000 cash-out amount, those costs consume 21.8% of your borrowed funds. A home equity loan with minimal or no closing costs delivers the full $55,000 for your use.

Similarly, if you're uncertain about your long-term plans for the property, lower upfront costs reduce the financial pain of selling within a few years. Refinancing requires several years of homeownership to recoup closing costs through lower payments or interest savings. Home equity loans with minimal costs carry less risk if your circumstances change unexpectedly.

4. The Rate Lock-In Effect: When Second Mortgages Make Perfect Sense

The rate lock-in effect represents one of the most powerful factors influencing the second mortgage versus refinancing decision in 2026. This phenomenon occurs when homeowners possess mortgages with interest rates significantly below current market rates, creating strong disincentives to refinance regardless of how much equity they want to access.

The 2020-2021 period created an unprecedented cohort of homeowners with ultra-low rate mortgages. Freddie Mac data shows annual average rates of 3.11% in 2020 and 2.96% in 2021, with some weekly readings dipping below 2.70% in late 2020 and early 2021.

Millions of homeowners either purchased or refinanced during this window, locking in rates that now look extraordinarily attractive compared to current 6.18% averages.

For these homeowners, cash-out refinancing makes almost no financial sense in 2026's rate environment. Consider the mathematics on a $300,000 remaining balance. Current mortgage at 3.00% gives you a monthly payment of $1,265, remaining interest over 25 years of $79,500, and total amount paid of $379,500. Cash-out refinance to $350,000 at 6.18% (accessing $50,000 equity) gives you a monthly payment of $2,130, total interest over 30 years of $416,800, and total amount paid of $766,800.

The monthly payment increases by $865 ($10,380 annually), and you'd pay an additional $337,300 in interest over the new loan's life compared to your existing mortgage. This enormous cost stems from refinancing the original $300,000 balance from 3.00 to 6.18%, not just borrowing the incremental $50,000.

Now compare the second mortgage alternative. Keep existing $300,000 mortgage at 3.00% with monthly payment of $1,265 (unchanged) and remaining interest over 25 years of $79,500 (unchanged). Add $50,000 home equity loan at 8.75% for 10 years with monthly payment of $396, total interest over 10 years of $21,545, and total amount paid of $71,545. Combined monthly payment is $1,661 ($469 less than refinanced payment) and combined total interest is $101,045 ($315,755 less than refinanced scenario).

The second mortgage costs you an extra $21,545 in interest compared to borrowing at 6.18%, but you save $337,300 by maintaining your 3.00% rate on the original balance. The net savings of approximately $315,755 demonstrates why second mortgages represent the optimal choice for most homeowners who refinanced during 2020-2021.

The National Association of REALTORS®' December 2025 market commentary notes this lock-in effect significantly constrains housing inventory as existing homeowners hesitate to sell homes with favorable mortgage rates. This same dynamic makes second mortgages the clear winner for accessing equity without sacrificing the rate advantage these homeowners currently enjoy.

The decision shifts only if you find yourself needing to move regardless of rate considerations. If you're selling the home anyway, the question becomes moot since you'll pay off the existing mortgage through the sale proceeds. Similarly, if you're refinancing for reasons beyond accessing equity such as removing private mortgage insurance or changing loan terms, you might accept the rate increase for other benefits.

5. Qualification Requirements and Equity Limitations

Qualification requirements and maximum loan-to-value ratios differ between refinancing and second mortgages, sometimes making one option accessible when the other isn't despite similar credit profiles and income levels. Understanding these distinctions helps you determine which path forward makes sense given your specific financial situation.

Cash-out refinancing on primary residences typically limits you to 80% loan-to-value ratio according to Fannie Mae and Freddie Mac conventional loan guidelines, meaning you must maintain at least 20% equity after the refinance completes. Some government-backed programs like VA loans allow higher LTVs up to 100% for eligible veterans according to Department of Veterans Affairs lending standards, but conventional conforming loans stick to the 80% standard. FHA cash-out refinances allow up to 80% LTV as well according to Federal Housing Administration program guidelines.

The LTV calculation works straightforwardly. If your home appraises for $400,000, an 80% LTV cap limits your total loan to $320,000. If you currently owe $240,000, you can access up to $80,000 through cash-out refinancing while staying within the 80% threshold.

Second mortgages, particularly home equity loans, sometimes allow combined loan-to-value ratios between 85 and 90% depending on credit scores and lender appetite for risk. The combined LTV (CLTV) adds your first mortgage balance and your second mortgage amount, then divides by your home's value.

Using the same example with a $400,000 home value and $240,000 existing mortgage, at 85% CLTV you get maximum combined loans of $340,000, allowing up to $100,000 home equity loan. At 90% CLTV you get maximum combined loans of $360,000, allowing up to $120,000 home equity loan.

This higher CLTV potential means second mortgages can sometimes access more equity than cash-out refinancing, particularly valuable if you've built substantial equity but need to maximize the amount you can borrow.

Credit score requirements also vary between the two options. Home equity loan products typically require minimum FICO scores of 680 for 80% CLTV, 700 for 85% CLTV, and 740 for 90% CLTV according to typical industry lending standards documented by credit bureaus. Cash-out refinancing generally requires 620 minimum scores for conventional loans according to Fannie Mae guidelines, though rates and terms improve substantially with scores above 700.

Debt-to-income ratio requirements remain similar for both products, typically capping at 43 to 50% depending on the lender and loan program according to the Consumer Financial Protection Bureau's qualified mortgage standards. The DTI calculation includes all monthly debt payments (existing mortgage, proposed new loan, credit cards, auto loans, student loans) divided by gross monthly income. Both refinancing and second mortgages count your housing payment in this calculation, though second mortgages add a second payment to the total.

Here's a practical DTI example. Suppose you earn $8,000 monthly gross income, creating a 43% DTI limit of $3,440 in maximum monthly debt payments. Your current debts include existing mortgage of $1,400, auto loan of $450, student loan of $280, and credit cards of $150 for total current debt of $2,280.

This leaves $1,160 of additional capacity before hitting the 43% cap. A cash-out refinance increasing your payment from $1,400 to $2,100 consumes $700 of that capacity, leaving $460 available for other debts. A home equity loan adding $500 monthly exceeds your capacity by $40, potentially disqualifying you.

One advantage second mortgages offer is they typically don't require full income documentation as rigorously as refinancing if you're borrowing smaller amounts. Some lenders offer streamlined home equity loans under $50,000 with reduced documentation requirements, though rates may be slightly higher on these programs.

6. Loan Types and Flexibility: Fixed Versus Variable, Lump Sum Versus Line of Credit

The product variations available within second mortgages provide flexibility that cash-out refinancing simply cannot match. While refinancing gives you a lump sum at closing with fixed terms, second mortgages offer multiple structures designed for different financial needs and preferences.

Cash-out refinancing delivers one product structure: a fixed-rate lump sum distributed at closing. You receive your equity cash immediately, your new mortgage begins amortizing that day, and you'll make the same payment for the entire 30-year term unless you refinance again. This works perfectly when you need a specific amount for a one-time expense like a major renovation, debt consolidation, or large purchase.

Second mortgages offer two distinct product types with different characteristics. Home equity loans operate similarly to refinancing in that they provide fixed-rate lump sum payments. You borrow a specific amount, receive the full balance at closing, and repay in equal monthly installments over a predetermined term, typically 10 to 20 years. The interest rate remains fixed for the entire repayment period.

Home equity loan terms of 10 and 20 years are available for primary and secondary residences. The shorter 10-year term carries higher monthly payments but significantly less total interest. On a $55,000 loan at 8.75%, a 10-year term gives you $436 monthly, $52,320 total paid, and $23,265 total interest. A 20-year term gives you $485 monthly, $116,400 total paid, and $61,400 total interest.

The longer 20-year term reduces the monthly payment by just $49 but costs an additional $38,135 in interest over the loan's life.

Home equity lines of credit (HELOCs) work fundamentally differently from both refinancing and home equity loans according to the Consumer Financial Protection Bureau's HELOC guidance. Rather than receiving a lump sum, you receive access to a revolving credit line similar to a credit card. You can draw funds as needed up to your approved limit, pay them back, and draw again during the draw period, typically 10 years.

During the draw period, most HELOCs require interest-only minimum payments on your outstanding balance, though you can pay principal as well. After the draw period ends, the line converts to a fixed repayment period, typically 20 years, during which you can no longer draw funds and must repay the outstanding balance through regular payments.

HELOC rates typically float based on the prime rate plus a margin. As of late December 2025, the prime rate stands at 6.50% according to Federal Reserve data. Most HELOCs charge prime plus 2.00 to 3.50 percentage points, creating current variable rates between 8.50 and 10.00%. These rates adjust when the Federal Reserve changes the federal funds rate, creating payment unpredictability that some borrowers dislike but others accept in exchange for the revolving credit flexibility.

The choice between fixed home equity loans and variable HELOCs depends on your specific needs. HELOCs work beautifully for ongoing projects like phased home renovations where you're unsure exactly how much money you'll need over time. You can draw $15,000 for the kitchen, repay some, then draw another $10,000 for the bathroom six months later. This flexibility prevents borrowing more than necessary and paying interest on unused funds.

Home equity loans make more sense when you know exactly how much you need and prefer payment predictability. The fixed rate protects you from future rate increases, and the structured repayment schedule builds principal reduction into every payment rather than allowing interest-only minimums.

7. Strategic Timing and Market Conditions in 2026

The timing of your decision between second mortgages and refinancing should account for current market conditions, interest rate trajectories, and your personal circumstances. The 2026 environment presents specific factors that favor one approach over the other depending on when you obtained your original mortgage and what you expect rates to do over the next few years.

Federal Reserve policy in 2026 centers on gradual rate cuts as inflation moderates toward the 2% target. The central bank cut the federal funds rate by 25 basis points in December 2025, bringing the target range to 3.50 to 3.75%, the lowest since 2022 according to the Federal Reserve's December 18, 2025 FOMC statement. Fed Chair Jerome Powell indicated the committee is well positioned to pause and evaluate how previous cuts filter through the economy after 75 basis points of reductions since September 2025.

The Fed's updated economic projections from December 2025 signal only one additional 25 basis point cut expected in 2026. This suggests mortgage rates will likely stabilize in the 5.90 to 6.30% range rather than declining dramatically back toward 4.00% or below.

Multiple forecasters including the National Association of REALTORS®, National Association of Home Builders, Fannie Mae Economic and Strategic Research Group, and Wells Fargo Economics align on expectations of 6.00 to 6.25% average rates through 2026.

This projected rate stability creates clear strategic implications for your decision. If you currently hold a mortgage originated in 2022 or 2023 at rates between 6.75 and 7.50%, cash-out refinancing to access equity while simultaneously lowering your rate makes excellent financial sense. You'd accomplish two goals with one transaction: accessing needed funds and reducing your ongoing interest costs.

Consider someone in Louisville with a $280,000 mortgage from October 2022 at 7.00%. Their current monthly payment is $1,862. If they need $40,000 for debt consolidation and home improvements, they could cash-out refinance to $320,000 at 6.18%, reducing their payment to $1,948, an increase of just $86 monthly while accessing $40,000 cash. The rate reduction from 7.00 to 6.18% partially offsets the payment increase from borrowing additional money.

Over 30 years, this refinancing strategy saves substantial interest compared to maintaining the 7.00% loan while adding a second mortgage at 8.75%. The blended cost of refinancing everything to 6.18% beats paying 7.00% on the first mortgage plus 8.75% on a separate $40,000 second mortgage.

Conversely, homeowners with 2020-2021 mortgages below 3.50% should almost never refinance in the current rate environment regardless of whether rates drop another 50 basis points through late 2026. Even if rates fall to 5.50%, the increase from 3.00 to 5.50% on your existing balance costs far more than the interest savings from borrowing additional money at 5.50 instead of 8.75% through a second mortgage.

The one scenario where 2020-2021 refinancers might consider cash-out refinancing is if they need to access very large amounts of equity that exceed typical second mortgage lending limits. If you need $200,000 and your home value and income support it, cash-out refinancing might be your only option since few lenders offer second mortgages that large.

Market competition among lenders also affects the decision. The rate lock-in effect has dramatically reduced refinancing volume as millions of homeowners possess no incentive to refinance. This has intensified competition for second mortgage business, with many lenders offering no-closing-cost home equity loans or aggressively competing on rates to capture this growing market segment. The Mortgage Bankers Association reported a 22% increase in second lien originations in Q1 2025 compared to Q1 2024 according to their quarterly lending forecast, reflecting this market shift.

The temporary nature of current conditions argues for moving relatively quickly if you've identified a genuine need for equity access. Interest rates won't remain at exactly 6.18% indefinitely, they'll fluctuate based on economic data, inflation reports, and Federal Reserve actions. If rates drop further to 5.75 or 5.50% over the next 6 to 12 months, borrowers with 2022-2023 mortgages above 6.75% would benefit from refinancing sooner rather than later. Those with 2020-2021 mortgages should act on second mortgages whenever the need arises without concerning themselves with minor rate fluctuations on products they should take regardless of modest rate changes.

Summary: Choosing the Right Path for Your Equity Access Needs

The fundamental distinction between second mortgages and refinancing shapes every aspect of your borrowing decision: payment structure, total costs, qualification requirements, and long-term financial flexibility. Refinancing works best when you can maintain or improve your current interest rate while accessing equity, making it ideal for borrowers with 2022-2023 mortgages at 6.75% or higher who can refinance to today's 6.18% average reported by Freddie Mac. Second mortgages make overwhelming financial sense for homeowners who refinanced during 2020-2021 at rates below 3.50%, as preserving those ultra-low rates on your existing balance saves far more money than the higher interest costs on the incremental borrowing.

The closing cost advantage of second mortgages, often $3,000 to $5,000 in savings versus refinancing according to Consumer Financial Protection Bureau cost data, particularly benefits borrowers needing funds quickly or uncertain about long-term homeownership plans. The product flexibility of HELOCs versus fixed-rate home equity loans allows you to match the borrowing structure to your specific needs, whether one-time lump sum or revolving credit for ongoing expenses.

Current 2026 market conditions with mortgage rates stabilizing in the low 6% range and Federal Reserve policy pivoting to gradual cuts create a relatively favorable environment for both strategies compared to the 7% plus rates of 2023. However, the rate lock-in effect affecting millions of homeowners with pandemic-era mortgages means second mortgages will continue dominating the equity access market for this cohort regardless of how much rates decline from current levels.

The optimal choice depends entirely on your existing mortgage rate, the amount of equity you need to access, your credit profile and income level, and how long you plan to maintain the property. Run the detailed calculations comparing total interest costs, monthly payments, and qualification likelihood for both options before making your decision.

Frequently Asked Questions

A second mortgage might be better than refinancing. When a low-rate mortgage is refinanced to current higher rates to build equity, the total costs go up a lot. If you keep making your current payments on a $250,000 loan with a 3% interest rate for the next 27 years, you will pay about $129,640 in interest. If you refinance your house for $300,000 at 6.18% and take out $50,000 in equity, you will have to pay about $357,000 in interest over the next 30 years. The extra $227,360 in interest would more than make up for any savings you might get by borrowing the $50,000 at a lower rate. Getting a second mortgage at 8.75% interest on that $50,000 would cost you more money than refinancing at 6.18%, but keeping your 3.00% rate on the first $250,000 amount more than makes up for the difference. If you need a lot of equity above the usual limits for second mortgages, you may have to refinance, even though it will cost you money. Freddie Mac's historical rate data shows that second mortgages are the best option for anyone whose rates were below 4.00% during the pandemic, unless something major happens.

As of late 2025, home equity loan rates are usually 2.00 to 3.50 percentage points higher than the rates for first-time mortgage refinancing. Freddie Mac says that the average 30-year fixed mortgage rate was 6.18% on December 24, 2025. Bankrate's poll found that the average interest rate on a home equity loan is between 8.50 and 9.50%. The exact range depends on things like the size of the loans, the number of lenders competing for them, and the credit ratings of the borrowers. The Consumer Financial Protection Bureau says that second mortgages are in second lien status, which means that they will only be paid back after the first mortgage in the event of a property foreclosure. Because lenders are taking on more risk, borrowers have to pay higher interest rates. Home equity lines of credit now have rates that are similar to or slightly higher than those of fixed home equity loans. The Federal Reserve's prime rate affects these rates, which range from 8.75% to 10%. The spread changes over time because of changes in market conditions and how much risk investors are willing to take. Because of the risk of a second lien, lenders want a bigger down payment. This makes the gap bigger when the economy is uncertain or property prices are falling. The gap may get smaller when the economy is doing well and the housing market is stable or getting better. The current small spreads show that lenders are right to believe that property prices will stay the same in 2026. They also know that second liens are more likely to end in foreclosure than first mortgages.

Yes, you can combine your first and second mortgages to make a new first mortgage. This option is popular with homeowners because it makes managing and paying off debt easier. This method works even better when you can lower the interest rate on your main mortgage and get rid of the second mortgage payment, which usually has a higher interest rate. With the new combined loan, you only have to make one payment each month at one interest rate. It will pay off both of your existing debts in full. Following the rules is very important, especially when it comes to the loan-to-value ratio limits. Fannie Mae and Freddie Mac say that the usual limit for a conventional refinancing is 80% LTV. This means that after you refinance, the total of your two current loans can't be more than this amount. If your home is worth $400,000, for example, your new loan amount can't be more than $320,000. If your first mortgage is $260,000 and your second mortgage is $70,000, you would need to bring $10,000 in cash to the closing to be under the 80% limit. This would add up to $330,000. The Consumer Financial Protection Bureau says that to get a mortgage, you need to have enough income and a debt-to-income ratio that is easy to handle. Your credit score affects both the rate and whether or not you can get a loan. Before you decide to combine your debts, think about your current rates very carefully. If, for example, your first mortgage starts at 3.00% in 2021 and your second mortgage starts at 9.00% in 2024, taking the 9.00% part out of your blended cost may not stop it from going up. Before you go any further, do the math to find out how much more interest the current deal costs overall than a combined refinancing.

The value of your home and the amount you owe will determine whether you can get a refinancing or a second mortgage. Fannie Mae and Freddie Mac's traditional lending standards say that you usually need to keep 20% ownership during the refinancing process. This means that the total amount of your new loan can't be more than 80% of what your house is worth right now. If your home is worth $350,000, you can borrow up to $280,000 when you refinance. If you have $220,000 in debt, refinancing with a cash-out option could give you up to $60,000. The Department of Veterans Affairs lets LTVs go up to 100% for some programs, like VA loans for qualified veterans. Depending on your credit score and the lender's rules, the total loan-to-value ratio for a second mortgage could be as high as 85 to 90%. According to the credit bureaus and the banking industry, the normal FICO score for a home equity loan is 680 for an 80% CLTV, 700 for an 85% CLTV, and 740 for a 90% CLTV. If your CLTV is 85% and your first mortgage is $220,000 on a $350,000 property, you can borrow up to $297,500, plus up to $77,500 more in a second mortgage. With a 90% CLTV, you could get a second mortgage for up to $95,000, bringing your total to $315,000. Because of these stricter CLTV rules, second mortgages might get more equity than cash-out refinancing in some cases. This is a lifesaver for when you really need to borrow money. According to research by the Federal Reserve on mortgage pricing, rates tend to go up with CLTV because lenders are more likely to lose money when the debt-to-value ratio is higher.

Closing costs are one of the most important things to think about when making a choice because they are very different for refinancing and second mortgages. According to the Consumer Financial Protection Bureau, closing costs for cash-out refinancing usually range from 3% to 4% of the new loan amount. Most borrowers pay somewhere in the middle. A $300,000 refinancing usually costs between $6,000 and $18,000 to close. These costs usually fall between $9,000 and $12,000. Costs for processing and underwriting range from $125 to $250. Costs for title searches and insurance range from $700 to $1,500. Costs for credit reports range from $30 to $50. Costs for recording range from $125 to $250. Costs for appraisals range from $400 to $600. You might be able to add them to your loan total instead of paying for them all at once at closing. Your principal, on the other hand, will go up, which means that your monthly payment and the total interest you pay will also go up. In 2026, there will be a lot of competition for home equity loans, so lenders will usually use low or no closing costs as a selling point. The fees that do apply are usually between $500 and $3,000, which is about 25% to 30% of what it would cost to refinance a loan of the same size. The lender usually pays for the title work, the origination costs, and the appraisal. To make up for these costs, interest rates might go up a little (0.25 to 0.50 percentage points). According to data from the Federal Reserve's consumer lending program, this upfront savings can be very helpful for borrowers who need money quickly or aren't sure what their long-term housing goals are. For one thing, you won't get back the money you spent on closing costs through lower interest rates or payments until you've owned the property for a while. Home equity loans usually have lower closing costs than HELOCs. Sometimes the whole price is less than $500, and other times the price is completely free during sales.

If you need a large amount of money right away, you should apply for a home equity loan. If you want to use the money for regular expenses, a HELOC is the best option. Home equity loans are similar to regular installment loans in that they let you borrow a certain amount and pay it back over a set amount of time, usually 10 to 20 years, in equal monthly payments. Because the interest rate stays the same during the repayment period, you can better plan your finances. This type of loan is a good choice for debt consolidation, big home improvements with known costs, and big purchases like down payments on cars. The CFPB says that home equity lines of credit work like credit cards, but they are backed by the value of your home. You can borrow as much money as you want, whenever you want, with a revolving credit line. You can do this for up to ten years. During this time, you will have many chances to borrow, pay back, and borrow again. You can usually pay off both the principal and the interest on most HELOCs during the draw period. However, you usually have to pay off the principal as well. For twenty years, you can make draws. After that, you can't make any more draws. You have to pay back the whole amount while this is going on. The Federal Reserve's prime rate shows that the current interest rates on home equity lines of credit (HELOCs) are between 8.75% and 10%. Because of this, your payment could go up or down depending on what the Federal Reserve does with interest rates. You can add or remove credit as needed with a home equity line of credit (HELOC). This makes it great for projects like remodeling multiple rooms or other projects where the final cost and completion date are not known. You can get a $15,000 kitchen loan and a $10,000 bathroom loan with the same terms, which means you can pay back part of the loan over six months. You only have to pay interest on the money you actually use. Paying only interest during the draw period may help your cash flow, but it will also keep you from building equity.

The amount of mortgage or home equity loan interest you can deduct from your taxes depends on your situation and how you use the money. If you itemize your deductions and the loan was used to buy, build, or make major improvements to the home that secures the mortgage, you can deduct the interest on up to $750,000 of debt ($375,000 if you are married and file separately) each year. The Tax Cuts and Jobs Act says that this benefit will be available until 2025. This rule applies to all types of mortgages, including first-time, refinancing, and second mortgages like HELOCs and home equity loans. You can only use the money you borrow for home improvements that are eligible. That is the most important thing. You can deduct the cost of a $50,000 home equity loan to fix up your kitchen and bathrooms. You won't be able to deduct the interest if you use $50,000 to pay off credit cards or buy a car. The rules are the same if you want to refinance to get cash out. If you refinance your $200,000 mortgage into a $250,000 loan and use the $50,000 in cash to improve your home, you can deduct the interest on the whole $250,000. If you use the $50,000 for something other than a house, you will only have to pay interest on the first $200,000 of debt. The total amount of mortgage debt you have on all of your homes cannot be more than $750,000. If you have a first mortgage of $500,000 and a second mortgage of $300,000, you can only deduct the interest on $750,000. To get the most out of your itemized deductions, you need to go over the limit for the standard deduction. According to the IRS tax law, the standard deduction for married couples filing jointly is $29,200 and for single taxpayers it is $14,600 in 2025. You won't be able to claim the mortgage interest deduction if your total itemized deductions (which can include mortgage interest, state and local taxes up to $10,000, and charitable contributions) are more than these limits. Many taxpayers are realizing that the cost of borrowing money after taxes is higher now that the home equity interest deduction is no longer available for all uses of home equity.

If you refinance your first mortgage with a rate-and-term loan that doesn't give you any more money, your second mortgage won't be affected. The second mortgage pays off the rest of the first mortgage. Your second mortgage's terms, payment, and lien status are all still the same. But if you want to get cash from your equity by refinancing your original mortgage, things get worse. The amount of the refinancing and your goals will determine whether the new first mortgage needs to pay off the old first mortgage and, if so, the second mortgage as well. Most cash-out refinances get rid of second mortgages, which means that the new loan is the most important one. This is how mortgage financing usually works. If you want to keep your second mortgage but refinance your first, the best way to do this is with a rate-and-term refinance that only covers the amount of your current first mortgage. If you want to keep your second mortgage holder in second place after the refinance, you can ask some lenders about second mortgage refinancing options. This means that the lien has been moved from the second mortgage holder to the new first mortgage. The second mortgage lender must sign a written agreement for this subordination, but they don't have to. Lenders may charge processing fees of $50 to $500 for subordination. The subordination process will make it harder and take longer to refinance your loan. It usually pushes back the closing date by one or two weeks. There aren't many times when it's smart to keep a second mortgage while refinancing the first one. If you refinanced your first mortgage at a low rate in 2020 or 2021 and then took out a second mortgage at a higher rate, you could do a rate-and-term refinance of the first mortgage. This would let you keep your current terms and maybe refinance the second mortgage separately if rates on second mortgages have gone down.
