One inquiry is the first step in creating a budget for a home: what monthly payment can you genuinely afford without living in poverty? With the data and reliable sources that make the math work for your circumstances, this book leads you through 12 distinct processes, from figuring out real take-home pay to sizing the down payment to your loan type.
Every borrower situation is different. When someone calls and says they're ready to buy a house, the first conversation rarely starts with the listing they liked or the down payment number they read somewhere. It starts with their budget, because the budget is what determines which house, which loan program, and which monthly payment actually fits their life.
A lot of buyers skip this step. They get prequalified, see a number, and start shopping at the top of it. The problem is that the qualifying number tells you what a lender will lend, not what you can comfortably pay. Those are two different numbers, and the gap between them is where overstretched mortgages live.
This guide walks through 12 steps that turn vague affordability into specific monthly numbers. Some of these will feel obvious. Some will surface costs most first-time buyers do not see coming. By the end, you should have a clear picture of what house price actually fits the income you bring home, the savings you have, and the life you want to be living three years from now.
The number you make on paper and the number that lands in your checking account are not the same thing. Federal taxes, state taxes, Social Security, Medicare, health insurance premiums, retirement contributions, and any other pre-tax deductions all come out before the money is yours. For a household earning $90,000 in gross annual income, the actual after-tax, after-deductions take-home in most states lands somewhere in the $65,000 to $72,000 range, depending on filing status, retirement contribution rate, and state of residence.
Mortgage qualification works off your gross income because that is what underwriting can verify on a tax return or pay stub. But your monthly budget runs off net income, because that is the money actually available to pay bills. Working off the wrong number is one of the most common reasons buyers feel financially squeezed in the first year of ownership.
Pull your last three pay stubs. Add up the net amounts. Multiply by the appropriate factor for your pay frequency: 26 for biweekly, 24 for semi-monthly, 12 for monthly, or 52 for weekly. That total is your annual take-home. Divide by 12 and you have your monthly take-home. This is the number every other step in this guide refers back to.
If your income is variable, including commission-based, self-employed, or overtime-driven sources, average the last 24 months. Lenders will average a longer history when underwriting your application; you should do the same when budgeting. Spiking high months in your math leads to a budget that only works in the good months, which is no budget at all.
A worked example helps. Consider a married couple filing jointly with $90,000 in combined gross annual income, living in a state with a 5% flat income tax. Federal tax at the standard deduction lands around $7,000 to $8,000 per year for that bracket. Social Security and Medicare combined are 7.65% of gross, or roughly $6,900. State income tax is roughly $4,500. Health insurance premiums run $200 to $400 per month for an employer-sponsored plan, or $2,400 to $4,800 per year. A 6% 401(k) contribution is $5,400. Add those deductions and net annual income lands at roughly $61,000 to $66,000, or $5,100 to $5,500 per month. That is the number to budget against, not the $7,500 monthly gross. The gap matters.
The 28/36 rule is the standard rule lenders use for housing affordability. The first number says your housing payment, including principal, interest, property taxes, homeowners insurance, and any HOA fees, should not exceed 28% of your gross monthly income. The second number says your total monthly debt obligations, housing plus car loans, student loans, credit card minimums, and other recurring debt, should not exceed 36% of your gross monthly income. The Consumer Financial Protection Bureau references this framing in its qualified-mortgage guidance, and most underwriting systems apply some variant of it.
Here is how the math works on a household earning $7,500 per month gross. The 28% housing ceiling is $2,100. The 36% total-debt ceiling is $2,700. If that household already pays $400 toward an auto loan and $150 toward a student loan, their available housing payment is the lower of $2,100 from the housing rule or $2,700 minus $550 in other debt, which is $2,150. The binding constraint is the 28% ceiling, so they should target a $2,100 monthly housing payment, not the $2,150 the 36% rule allows.
Most loan programs allow higher debt-to-income ratios than 36% in practice. The current Federal Housing Administration guidelines, for instance, allow debt-to-income ratios up to 43% in standard cases and higher with compensating factors, per HUD's underwriting handbook. Just because you can qualify at 43% does not mean the budget feels comfortable at 43%. The 28/36 framing is your comfort target. Higher ratios are your qualification ceiling. Most AmeriSave borrowers find that landing somewhere between the two leaves room for the rest of life.
Before you set a target monthly housing payment, you need to know where your money actually goes today. Most buyers underestimate their monthly spending by 15 to 25%, because the small recurring costs like subscriptions, food delivery, gas refills, and the occasional weekend trip do not register the way the big bills do. A three-month tracking exercise fixes this.
Pull your last three months of bank and credit card statements. Categorize every transaction. Use whatever buckets make sense for your life. Common categories are housing for current rent or mortgage, utilities, transportation including car payment and gas and insurance and public transit, food covering groceries plus restaurants, healthcare premiums and copays, insurance premiums for auto and renters and life, debt payments, savings contributions, subscriptions, personal spending, and travel. Total each category.
Compare your actual spending to your assumed spending. The gap is larger than expected. Once you have a real spending picture, you can identify which categories will rise after you buy. Utilities almost always do, and transportation often does if the new home changes your commute. The Bureau of Labor Statistics publishes Consumer Expenditure Survey data showing average household spending across categories, which is useful as a sanity check, but your own numbers are the ones that matter for your budget.
The right down payment is not a single number. It depends on which loan program fits your situation. Common minimums per the loan-program agency that sets each rule are: 0percent for VA loans, available to eligible service members, veterans, and surviving spouses per the Department of Veterans Affairs; 0% for USDA loans on properties in eligible rural areas; 3% for some conventional first-time home buyer programs such as Fannie Mae HomeReady and Freddie Mac Home Possible; 3.5% for FHA loans with a credit score of 580 or higher; and 10% for FHA loans with a credit score between 500 and 579, per HUD's published guidelines.
On a $400,000 home, those minimums work out to: $0 for VA or USDA, $12,000 for a 3% conventional, $14,000 for a 3.5% FHA, $40,000 for a 10% FHA, and $80,000 for a 20% conventional. The gap between $14,000 and $80,000 is enormous, and it is the single biggest variable in how long it takes a household to be ready to buy.
To see how the down payment moves the monthly payment, run the same $400,000 home at four different down levels with a 7% 30-year fixed rate. At 3.5% down, the loan amount is $386,000 and the principal-and-interest payment is $2,569, plus FHA upfront and annual MIP. At 10% down, the loan amount is $360,000 and the P&I payment is $2,395. At 20% down, the loan amount is $320,000 and the P&I payment is $2,129, with no PMI. The $440 monthly difference between 3.5% down and 20% down compounds to over $158,000 in interest savings across a 30-year term, before counting the PMI line item that disappears at 20% down on a conventional loan.
The temptation is to put down as little as possible to get into the house faster. Sometimes that is the right answer. Sometimes it is not. A smaller down payment means a higher monthly payment, mortgage insurance for some programs, and less equity if home prices move sideways or down. A larger down payment means a lower monthly payment, no mortgage insurance for conventional loans at 20% or above, and more cushion. Maybe a 3.5% FHA does not fit because you have the savings for 10% and would prefer the lower payment. But for a borrower who has been renting for years and is finally ready, a 3.5% FHA may be exactly the right tool. According to the National Association of REALTORS®
Profile of Home Buyers and Sellers, the typical first-time home buyer puts down 10%, and the typical repeat buyer puts down 23%. There is no single right answer. Your AmeriSave loan officer can help you compare two or three down-payment scenarios side by side to see which monthly payment and which timeline make the most sense for your file.
I run this conversation with borrowers across the Dallas-Fort Worth region all the time. The borrower comes in fixated on a number they read somewhere, and the answer for their actual situation is often a different program at a different down-payment level. Shopping a 5% conventional against a 3.5% FHA is not the same comparison for a 640-credit borrower as it is for a 760-credit borrower. The mortgage insurance line moves, the rate moves, and the monthly payment moves with them. The right structure comes out of running the numbers on your file, not on the file someone else closed last month.
Closing costs are not part of your down payment. They are an entirely separate cost category that runs between 2 and 5% of the loan amount, per Freddie Mac's published guidance. On a $400,000 purchase with a $380,000 loan amount, closing costs land in the $7,600 to $19,000 range, depending on state, lender, and which costs the seller agrees to cover.
What is in that bucket: lender fees such as origination, processing, and underwriting; third-party fees including appraisal, credit report, and flood certification; title fees that include title insurance for the lender and often for the owner, plus settlement or escrow charges; recording fees and transfer taxes, which vary widely by state and county; and prepaid items including the first year of homeowners insurance, several months of property taxes, and prepaid daily interest from your closing date to month-end. The Loan Estimate document your lender provides within three business days of application breaks out every line item, per CFPB disclosure rules under the TILA-RESPA Integrated Disclosure rule, also known as TRID.
Some closing costs can be reduced through negotiation, seller concessions, or lender credits. Some are fixed by your state or county and cannot be moved. Plan for the upper end of the range when budgeting, then adjust downward if the actual Loan Estimate comes in lower. Saving for closing costs as a separate target, rather than treating them as part of the down payment fund, prevents the situation where a buyer hits the down payment number and then realizes they need to come up with another $10,000 to close.
An emergency fund is not part of your down payment or your closing cost reserve. It is money that stays in your account after you close, so a job loss, medical event, or major repair does not turn into a missed mortgage payment. The Consumer Financial Protection Bureau recommends a target of three to six months of essential expenses, and for new homeowners the higher end of that range is the safer plan.
Calculate your post-closing essential monthly expenses. That includes the new mortgage payment with principal, interest, taxes, insurance, mortgage insurance if applicable, and HOA fees if applicable, plus utilities, transportation, food, healthcare premiums, and minimum debt payments. Multiply by six. That is your emergency fund target.
On a household with $5,500 in monthly essential expenses post-closing, the six-month emergency fund target is $33,000. That sits in a high-yield savings account, separate from checking, separate from the down payment fund, and separate from your retirement accounts. It is the buffer that lets you stay current on the mortgage if income drops or a roof leak shows up in month four. Lenders also like to see reserves on your application; some loan programs explicitly require two to six months of mortgage-payment reserves depending on loan type and property type, per Fannie Mae and Freddie Mac underwriting guides. A funded emergency fund satisfies both your personal cushion and any lender reserve requirement at the same time.
Property taxes are one of the largest variable costs in homeownership and one of the most location-dependent. The national average effective property tax rate is approximately 1.0% of home value annually, per the Tax Foundation, but state-level effective rates range from under 0.4% to over 2.2%. Within a state, county and municipal rates can swing the number by hundreds of dollars per month.
On a $400,000 home, a 0.5% effective rate produces $2,000 per year, or $167 per month, in property taxes. A 1.5% effective rate produces $6,000 per year, or $500 per month, on the same home. That $333 monthly difference is real buying power. Two identical homes at identical purchase prices in two different counties can have monthly payments that differ by hundreds of dollars purely because of the tax line item.
State-level effective rates illustrate the spread. According to the Tax Foundation, the lowest-rate states sit at or near 0.3%, including Hawaii, and Alabama. New Jersey and Illinois are the only two states with effective rates above 2%, at 2.23% and roughly 2.07%. Connecticut, New Hampshire, and Vermont sit in the 1.5 to 1.9% range. A buyer comparing a $400,000 home in Birmingham, Alabama, to a $400,000 home in northern New Jersey is comparing roughly $1,520 per year in property taxes to roughly $8,920 per year. That difference, by itself, can move a borrower in or out of the 28/36 affordability range. Run the math on the actual address, not on the average for the country.
Do not estimate property taxes from a national average when you have an actual address in mind. Pull the most recent tax assessor's record for the specific property. Public records are searchable on most county assessor websites. The current annual tax bill is the floor for your estimate; reassessment after sale can push the number higher in some states, particularly if the sale price exceeds the prior assessed value. Your AmeriSave loan officer will pull the tax record as part of the disclosure process, and the property tax escrow amount will appear on your Loan Estimate. Verify that number matches what the assessor's office is publishing for the property.
Homeowners insurance protects the structure and your liability as the owner. Recent industry analyses by the Insurance Information Institute and the National Association of Insurance Commissioners place the national average annual premium near $2,500 per year for a typical single-family home, with premiums ranging from under $1,000 in the lowest-cost states to over $6,000 in coastal and wildfire-exposed regions. On a $400,000 home, expect a monthly insurance line in the $150 to $300 range for most policies in moderate-risk areas, and considerably higher in coastal Florida, parts of California, and tornado-belt states.
Mortgage insurance is a separate line that applies to most loans with less than 20% down. On conventional loans, this is private mortgage insurance, or PMI, with annual premiums ranging from about 0.46% to 1.5% of the loan balance, depending on credit score and loan-to-value ratio, per the Urban Institute's Housing Finance Policy Center. PMI on conventional loans drops off automatically once your loan-to-value ratio reaches 78%, per the Homeowners Protection Act, and a borrower can request cancellation at 80% loan-to-value.
FHA loans carry a different structure. There is an upfront mortgage insurance premium of 1.75% of the loan amount, which most borrowers roll into the loan rather than paying at closing, plus plus an annual MIP that ranges from 0.15% to 0.75% of the loan balance depending on loan term and loan-to-value ratio, per HUD's MIP guidance. On most FHA loans originated today, the annual MIP stays for the life of the loan unless the borrower refinances out of FHA into a conventional product. VA loans do not carry monthly mortgage insurance but charge a one-time funding fee that ranges from 1.25% to 3.3% of the loan amount, per the Department of Veterans Affairs, with exemptions for veterans receiving disability compensation. USDA loans charge an upfront guarantee fee plus an annual fee, similar in structure to FHA.
All of these go in the monthly housing math. AmeriSave's loan officers walk through the specific insurance and mortgage-insurance numbers on every quote so the monthly payment shown is the full payment, not the principal-and-interest-only number that some quote tools display.
Three categories of cost regularly surprise first-time home buyers. The first is homeowners association fees. If you are buying in a condo, planned community, or HOA-governed neighborhood, monthly dues can range from under $100 to over $1,000, depending on the property type and what the association covers. Read the HOA documents before you make an offer. Look for the current monthly dues, the special assessment history, which is the record of large one-time charges levied to fund major repairs, and the reserve fund balance, which is the association's savings account for future maintenance.
The second is utilities. Renters pay a portion of utilities, but homeowners pay all of them: electricity, gas, water, sewer, trash, internet, and any other service the property uses. The Energy Information Administration tracks average residential utility costs, and the typical owned single-family home runs around $300 to $500 per month in combined utilities, depending on climate, square footage, and the age and efficiency of major systems. A 3,000-square-foot home in a hot climate with an older HVAC system can run $700 or more per month in utilities alone.
The third is the bucket of small recurring costs that come with ownership: lawn care or landscaping, pest control, gutter cleaning, snow removal in colder climates, and routine maintenance contracts for HVAC service, septic service if applicable, and well water testing if applicable. These are small individually but add $100 to $300 per month combined. Add all three categories to the housing math before you set the affordability ceiling.
The most underestimated cost of ownership is maintenance. The widely cited rule of thumb, referenced in Fannie Mae homeownership education materials and similar sources, is to reserve 1 to 3% of home value annually for repairs and replacement. On a $400,000 home, that is $4,000 to $12,000 per year, or $333 to $1,000 per month set aside in a maintenance fund.
Where the range matters: a newer home with recently replaced major systems runs at the lower end of the range. An older home with original roof, original HVAC, and original water heater runs at the upper end, because the major-system replacement cycle is approaching. A new roof runs $10,000 to $30,000 depending on size and material. A new HVAC system runs $7,000 to $15,000. A new water heater is $1,500 to $3,500. A full exterior paint or siding replacement is $5,000 to $20,000. Spread across the useful life of each system, those costs work out to the 1 to 3% range.
The mistake first-time home buyers make is assuming maintenance costs only happen when something breaks. They do not. Major systems wear on a schedule, and the schedule is shorter than most buyers expect. Setting up a separate maintenance savings account funded automatically each month means the money is there when the system needs replacement, rather than going on a credit card or pushing other goals back. AmeriSave's homeownership education content includes maintenance budgeting as a core topic for exactly this reason.
Two numbers control both whether you qualify and the rate you receive. The first is your credit score. FICO scores range from 300 to 850 and are calculated based on payment history at 35% of the score, amounts owed at 30%, length of credit history at 15%, credit mix at 10%, and new credit at 10%, per FICO's published methodology. Mortgage program minimums vary: FHA accepts scores as low as 500 with 10% down or 580 with 3.5% down, per HUD; conventional loans require 620 or higher; VA does not set a federal minimum but most lenders apply overlays around 580 to 620; USDA requires 640 or higher.
Within the qualifying range, your score drives your rate. The interest rate spread between a 620 score and a 760 score on the same loan is often 0.5 to 1.0 percentage points, which on a $300,000 loan over 30 years is tens of thousands of dollars in interest. Pull all three credit reports through AnnualCreditReport.com, the only federally authorized free source, at least four to six months before applying. Dispute any errors. Pay down credit card balances to under 30% of each card's limit, ideally under 10%, because credit utilization is the fastest-moving variable in your score.
Most score improvements show up on the next reporting cycle, which is 30 to 45 days after the change. That means a borrower who pays down credit card balances on the first of the month will see the improved score within 30 to 60 days. A borrower who closes an old account, on the other hand, may see the score drop because closing reduces total available credit and shortens average account age. Avoid closing accounts in the year before applying. Avoid opening new accounts in the same window, because new accounts shorten average account age and trigger hard inquiries that drop the score temporarily. The cleanest credit profile for a mortgage application is one with no recent activity, low utilization, and a clean payment history going back at least 12 months.
The second number is your debt-to-income ratio, or DTI. Front-end DTI is your housing payment divided by gross monthly income; back-end DTI is total monthly debt payments divided by gross monthly income. Most loan programs cap back-end DTI at 43 to 50% depending on program and compensating factors. To improve your DTI, the practical levers are increasing income, which is rare in the short term, paying down installment debt, and reducing minimum credit card payments by paying down revolving balances. Closing credit cards hurts your score and rarely helps your DTI; pay them down rather than closing them.
The mortgage rate quoted today may not be the rate you close at. Even with a rate lock, the lock period runs 30 to 60 days, and rates can move during that window for unlocked applications. More importantly, the rate quoted today is the rate at one point in the cycle, and budgeting only against that single rate ignores the reality that rates fluctuate.
Run the affordability math at the quoted rate, then run it again at a rate one percentage point higher and at a rate two percentage points higher. On a $300,000, 30-year fixed-rate mortgage, monthly principal and interest at 6% is $1,799. At 7%, it is $1,996. At 8%, it is $2,201. The $400 monthly difference between 6 and 8% is the difference between a payment that fits comfortably and a payment that strains the budget.
If the higher-rate payment still fits within the 28/36 framework, the budget has cushion. If it does not, the affordability target needs to come down, either by lowering the home price you target or by waiting until the down payment grows enough to reduce the loan amount. Freddie Mac's Primary Mortgage Market Survey and the Federal Reserve's H.15 release publish current weekly rate data, which is useful for checking where market rates are sitting at any given time. Your AmeriSave loan officer can run a side-by-side payment comparison at the current quoted rate and at higher hypothetical rates so the stress test is built into the file before you make an offer.
Finding the maximum amount that a lender would accept is not the goal of a home budget. Finding a payment that works with your salary, your ability to save money, and the upkeep requirements of property ownership are all important. You can translate an ambiguous affordability question into a precise monthly figure that remains consistent over the first and tenth years of ownership by following the twelve procedures mentioned above.
Run your actual take-home pay, use the 28/36 framework, keep track of your actual spending, size the down payment to the loan program that best suits your file, save closing costs separately, fund the emergency fund, include property taxes for the particular address, add insurance and mortgage insurance, account for HOA fees, utilities, and operating costs, set aside money for maintenance, audit your credit and DTI, and stress-test against a higher rate. The answer to what you can afford is no longer a guess once all those figures are in agreement. You own your file. The program that worked for your cousin may not work for you, and your neighbor's file may differ from your own. When you're ready to put actual numbers on the page, AmeriSave's loan experts can guide you through the same process using quotations for current rates and program-specific scenarios.
A $400,000 home with a $380,000 loan at a 7% interest rate has a principal-and-interest payment of about $2,528 per month, plus about $400 to $700 in taxes, insurance, and mortgage insurance, for a total monthly housing payment of $3,000 to $3,200 using the 28% housing ratio as a comfort target. You would require a gross income of $10,700 to $11,500 per month, or $128,000 to $138,000 annually, to remain at or below 28% of gross income.
This is significantly altered by two factors. The necessary income decreases with a lower interest rate and increases with a higher rate. A higher down payment lowers the needed income by lowering the loan amount and the mortgage insurance line. Before deciding on a target home price, many AmeriSave borrowers run the same calculation against three different rate and down payment scenarios because, according to the methodology cited in CFPB consumer guidance, minor adjustments to those inputs can change the required income by $10,000 to $20,000 annually.
A minimum credit score of 620 is usually required for conventional loans. According to HUD, FHA loans can accept scores as low as 500 with a 10% down payment or 580 with a 3.5% down payment. Although there is no statutory minimum for VA loans, most lenders use overlays between 580 and 620.
The rate-eligibility minimum is different from the qualifying minimum. Higher scores are given lower rates within each program, and the difference between a score of 620 and 760 is often between 0.5 and 1.0 percentage points.
A 1.0 percentage point rate difference of 7.5% versus 6.5% on a $300,000 loan over 30 years equates to about $200 monthly payments, or $72,000 over the course of the loan. The most effective ways to improve your rate are to pull your credit report from AnnualCreditReport.com four to six months before to applying, pay down revolving amounts to less than 30% of each card's limit, and dispute any inaccuracies.
Consider a household that makes $85,000 a year, is currently renting, has $20,000 saved, and has a credit score of 720. They are looking at properties between $325,000 and $375,000.
A $12,250 down payment is needed for a 3.5% FHA loan on a $350,000 home for the household. For the same house, a 3% conventional loan requires a $10,500 down payment. $17,500 is needed for a 5% conventional. $35,000 is needed for a 10% conventional. According to Freddie Mac, their $20,000 in savings already meets the minimum for any of the three lesser options, leaving $7,500 to $17,500 for closing expenses, or 2 to 5% of the loan amount. The ideal solution is a down payment that fits a monthly payment they can comfortably make while still leaving a six-month emergency fund in place after closing, not the lowest amount available. The National Association of REALTORS® states that the average first-time buyer puts down 10%, or $35,000 in this case.
The kind of debt and the interest rate determine this. Since the interest rate on high-interest revolving debt, such as credit cards with interest rates of 20% or more, is significantly greater than both your prospective mortgage rate and what your savings would earn, it is almost always paid off first. Federal student loans and single-digit vehicle loans are examples of low-interest installment debt that can be paid off concurrently with savings, particularly if doing so would leave you without any liquid funds.
Another factor is the debt-to-income ratio. According to Fannie Mae and Freddie Mac underwriting guidelines, paying off installment debt with 12 or fewer payments left may occasionally be removed from your DTI calculation if your DTI is already at or close to the program cap. Before strategically paying down a debt, speak with a loan officer. The best course of action will depend on the loan program you are pursuing and where your current DTI stands in relation to the cap. This study is routinely conducted by AmeriSave's loan professionals during a preapproval discussion.
According to Freddie Mac, closing costs range from 2 to 5% of the loan amount. That is between $6,000 and $15,000 on a $300,000 loan.
Due to significant differences in title insurance laws, transfer taxes, and recording fees, the range varies by state. The top end is occupied by expensive states in some areas of the Northeast and West Coast.
Depending on the state, closing costs for a $400,000 home with a $380,000 FHA loan might range from $7,600 to $19,000. Lender fees range from $1,500 to $3,500 and include origination, processing, and underwriting. $700 to $1,200 is added by third-party fees for flood, credit, and appraisal. The range of title and settlement fees is $1,500 to $4,000. Jurisdiction-specific recording and transfer taxes might cost anything from $200 to $5,000 or more. $3,000 to $6,000 is added by prepaid expenses such daily interest, property tax escrow for several months, and homeowners insurance for a year. According to CFPB regulations, your lender's loan estimate breaks out each line.
The 28% housing ceiling results in a maximum monthly housing payment of $2,333 at a gross annual income of $100,000. After deducting about $300 to $500 each month for taxes, insurance, and mortgage insurance, a 10% down payment at a 7% interest rate over 30 years supports a property price of $310,000 to $340,000.
Three variables are involved in the number's movement. Because principal and interest on a smaller loan account for a larger portion of the monthly payment, a larger down payment raises the affordability ceiling. Because a greater loan balance is supported by the same monthly payment, a lower interest rate causes it to shift upward. Because they soak up a portion of the 36% total-debt allotment, other monthly debt commitments force it to shift lower. Instead of using a straightforward income multiple, use a mortgage affordability calculator that considers all of these factors. Based on your unique income, debts, credit, and goal program, AmeriSave's preapproval procedure generates a fully underwritten affordability number.
Consider a borrower who wants to purchase a home with a goal monthly mortgage payment of $2,000 but has $45,000 in federal student loans on an income-driven repayment plan, with a current monthly payment of $250.
Before making a purchase, the borrower is not required to settle their school loans. How the student loan payment is handled in the debt-to-income computation is what counts. According to Fannie Mae and Freddie Mac guidelines, the actual income-driven payment for the majority of loan programs can be considered for DTI reasons provided it shows up on the credit report and is larger than zero. Instead of using the income-driven amount, lenders for various programs—including FHA in some circumstances—use a calculated payment based on a percentage of the outstanding balance, often 0.5 to 1.0%. The course of treatment varies depending on the program and the most recent guidelines, which have undergone multiple revisions in recent years. Before making any strategic payments, it is advisable to find out from your loan officer how your particular student loan situation will be calculated under the program you are considering. You may benefit from the income-driven payment at times and be harmed by the balance-based computation at other times. The answers to such questions are where the math originates.
