Key Takeaways

  • When making a choice, the majority of mortgage lenders use the middle score from all three main credit bureaus.
  • You can be eligible for FHA loans with a credit score as low as 580 with a 3.5% down payment or even 500 with a 10% down payment.
  • Over the course of the loan, even a 20-point variation in your credit score might affect your interest rate and cost you or save you tens of thousands of dollars.
  • Lenders consider your income, debts, and savings in addition to your credit score.
  • Paying off your credit card debt to less than 30% of your limit is one of the easiest strategies to raise your score before you apply.
  • Your credit score won't be affected in any way because prequalification is done using a soft credit check.
  • You can still obtain a mortgage with a lower-than-perfect score if the remainder of your financial situation is sound.

What Is a Credit Score for Mortgage Lending?

In essence, your credit score is a snapshot of your borrowing behavior. It provides lenders with information about how long you have been managing accounts, how much of your available credit you regularly use, and if you typically pay your payments on time. Equifax, Experian, and TransUnion are the three credit bureaus that monitor this data. Your score may differ between bureaus because each one may contain somewhat different data.

The lender will obtain your score from each of the three bureaus when you apply for a house loan. Typically, they accept the intermediate score. Therefore, the lender will choose 695 if your numbers are 680, 695, and 710. Your loan conditions, interest rate, and occasionally even the loan programs you are eligible for are all determined by that middle figure.

The majority of mortgage credit scores are derived from a mortgage-specific FICO model. Lenders currently utilize what are known as Classic FICO scores, which vary based on the credit agency and might be versions 2, 4, or 5. You wouldn't see these figures on a free credit monitoring app. Certain factors, including as how you've managed revolving accounts vs installment loans, are weighed differently by the mortgage-specific models. Because of this, borrowers are occasionally taken aback when their lender presents a figure that differs from what they anticipated.

You have a significant edge if you know what goes into this figure. Before you begin your house search, you can make adjustments that will help you save a significant sum of money over the course of your loan.

How Mortgage Credit Scores Work

Your credit behavior is divided into five categories by the scoring algorithms used by mortgage lenders, and each category has a distinct weight. The largest component is the payment history. It makes up around 35% of your final score. This implies that a single late payment can have long-lasting effects.

Next, at about 30%, is credit utilization. This indicates how much of your available credit you are currently use. The 70% utilization rate on a credit card with a $10,000 limit and a $7,000 load will lower your credit score. The lower the number, the better, as lenders prefer to see it below 30%.

About 15% is made up of the length of credit history. A lender can be more certain that your behavior is consistent the longer your accounts have been open and active. Every day, we at AmeriSave speak with customers who are concerned that their credit history is too short. If that sounds familiar, you may be surprised at how beneficial it is to keep your oldest accounts open and in good standing.

10% or so are new credit queries. Your credit score may drop a few points each time you apply for a new credit card or auto loan. Fortunately, questions about mortgages made within a 14- to 45-day period are combined and counted as a single query. so you may compare rates without being concerned that each lender will harm you in a different way.
Your credit mix accounts for the final 10%. Lenders want to see that you can manage various forms of credit, such as credit card debt, auto loans, and possibly student loans. A healthy variety demonstrates competence handling various responsibilities, although having only one kind of account isn't a deal-breaker.

This is a common mistake made by people. They believe that their credit score will drop if they check it. It won't. A self-check has no impact on your number and is a mild inquiry. In order to avoid any shocks when you meet with a loan officer, you should check your score on a frequent basis.

People frequently become confused by the discrepancy between the free score on your banking app and the one your lender pulls. Instead of the Classic FICO model used by mortgage lenders, the free score typically originates from a VantageScore model. The numbers rarely match because the two models evaluate your credit activity differently. Long-standing accounts are given greater weight by FICO, whereas VantageScore is typically a little more forgiving with thin credit files. In either way, the difference between the two can range from 10 to 40 points.

Pay attention to this next part, because it will affect anyone buying a home in the near future: the mortgage industry is in the middle of a major shift. The Federal Housing Finance Agency has approved two newer credit scoring models for Fannie Mae and Freddie Mac loans. FICO 10T and VantageScore 4.0 both use trended data, which means they look at your credit behavior over the past 24 months instead of just a single snapshot. If you've been steadily paying down debt and building good habits, these newer models could work in your favor. The rollout is happening now, so your lender may still be using Classic FICO or may have already switched.

Minimum Credit Score Requirements by Loan Type

Different loan programs have different floors when it comes to credit scores. Knowing which program fits your situation can save you a lot of frustration during the application process. I've been doing this since I was 18, and one of the most common questions I still hear is "what score do I actually need?" Let me break it down for each major loan type.

FHA Loans

FHA loans are backed by the Federal Housing Administration, and they're one of the most forgiving options out there for borrowers with lower credit. The official minimum is 500, but that comes with strings attached. If your score falls between 500 and 579, you'll need to put at least 10% down. Once you hit 580, the required down payment drops to just 3.5%.

FHA loans are popular with first-time home buyers for good reason. The guidelines are more flexible on credit, and the Consumer Financial Protection Bureau notes that FHA loans also allow higher debt-to-income ratios than many conventional programs. AmeriSave offers FHA loans with competitive rates, and our loan officers can walk you through the exact requirements for your score range.

Conventional Loans

Because conventional loans are not backed by the government, lenders bear greater risk. While some lenders have greater requirements, the majority of traditional programs require a minimum score of 620. You will often receive the greatest interest rates on a traditional loan if your score is higher than 740.

When Are You Looking To Buy A Home?

The trade-off with conventional loans is that you avoid paying the upfront mortgage insurance fee associated with FHA, even though the credit standards are stricter. For the duration of the loan, a conventional loan may be less expensive if your credit score is high enough to qualify. Additionally, you can completely avoid private mortgage insurance if you put down at least 20%, which increases your monthly savings.

Conventional loans are still an option for applicants in the 620–680 range, but the cost modifications can be substantial. Based on the mix of your down payment and credit score, lenders make what are known as loan-level pricing changes. A greater adjustment, which is incorporated into your rate, results from a lower score and a smaller down payment. This is where it makes a lot of sense to compare the statistics with an FHA quote.

VA Loans

VA loans are available to eligible veterans, active-duty service members, and some surviving spouses. The Department of Veterans Affairs doesn't set a minimum credit score on its own, but most lenders apply their own overlay of around 580 to 620. VA loans have a big advantage: no down payment and no private mortgage insurance. For qualified borrowers with even moderate credit, this is usually one of the most affordable paths to homeownership.

USDA Loans

USDA loans are built for home buyers in eligible rural and suburban areas. The program's automated underwriting system, called GUS, looks for a minimum score of 640. If your score falls below that, you're not automatically out, but you'd need to go through manual underwriting, which takes longer and requires more paperwork. Income limits apply too. If you meet the location and income guidelines, USDA loans offer zero down payment just like VA loans.

Jumbo Loans

Jumbo loans cover amounts that exceed the conforming loan limits set by the Federal Housing Finance Agency. Because these loans are bigger, lenders want more assurance that you can handle the payments. A minimum credit score of 700 is common for jumbo programs, and many lenders prefer 720 or above. You'll also need a larger down payment and solid cash reserves.

How Your Credit Score Affects Your Mortgage Rate

This is the section that has the biggest financial impact. Your credit score affects more than just your approval status. It has a direct impact on the interest rate you are offered, and over time, even a slight variation in rate can have a significant impact on your payments. One of the first things we go over with customers during the prequalification process is this, which AmeriSave loan officers witness on a regular basis.

Allow me to demonstrate this with actual numbers. Let's say you want to buy a house for $350,000. If you put down 10% of that amount, your loan balance would be $315,000. Using a fixed mortgage for 30 years:
You may receive a rate of about 6.5% if your credit score is 760. You would pay roughly $1,991 in principal and interest each month. You would pay about $716,760 over the course of 30 years.

What would happen if you received a score of 660? The interest rate on that same loan could be more like 7.25%. The monthly cost increases to almost $2,149. Over 30 years, the total amount paid was approximately $773,640.

The difference adds up to $158 a month and almost $56,880 over the course of the loan. All due to a credit score difference of 100 points. When you do the arithmetic on your personal circumstances, the numbers quickly seem extremely realistic. All loan programs routinely give more favorable rates to customers in higher credit levels, according to Freddie Mac.

Additionally, the rate tiers that lenders employ are not a smooth sliding scale. They frequently leap at specific breakpoints. Significant rate increases are frequently observed at 620, 660, 680, 700, 720, and 740. Before locking in a rate, it can be worthwhile to spend a few months raising your score if you're slightly below one of those requirements. Any short-term costs associated with waiting can be greatly outweighed by the savings over a 30-year period.

If you put less than 20% down on a traditional loan, your credit score also influences the price of private mortgage insurance. A borrower with a credit score of 760 may pay half the monthly PMI that a borrower with a score of 660 pays on the identical loan because PMI rates are partially determined by your credit score. The overall monthly difference between a great score and a mediocre one increases when you add that savings to the reduced interest rate. This is one of those fields where applying with a little advance planning pays off handsomely.

What Lenders Actually Look At Beyond the Number

Is your credit score the sole factor that matters to lenders, even though it opens doors? Not even near. Before making a choice, AmeriSave considers your entire financial situation, and in all honesty, that's how it should operate. One aspect of the plot is conveyed through a score. The holes are filled in by the rest.

The ratio of debt to income is significant. This is the portion of your monthly gross income that is allocated to debt repayment. Although FHA loans can occasionally reach 50% with significant compensatory factors, the majority of loan programs aim to keep your total DTI at or below 43%. Even a high credit score won't help you get authorized if your DTI is too high.

Stability in employment and income is also important. A minimum of two years of steady income is required by lenders. Typically, self-employed borrowers must present two years' worth of tax returns. Even if your credit score appears to be good, gaps in employment or significant fluctuations in income raise concerns.

Reserves of cash complete the image. After closing, lenders want to know if you have any money left over. Having two to six months' worth of mortgage payments in savings demonstrates to the lender that you can manage an unforeseen setback without falling behind right away. Because the stakes are larger in jumbo loans and investment property acquisitions, this is particularly crucial.

Ready To Get Approved?

The size of the down payment also matters. A higher down payment lowers the lender's risk, which occasionally makes up for a score that isn't quite where you want it to be. It aids in the overall risk picture but does not take the place of the credit requirement.

Steps to Raise Your Credit Score Before Applying

Homeownership is still an option even if your credit score isn't where it should be. It just indicates that you need to get some work done. The good news is that, if you approach it strategically, some acts can raise your score quite quickly.

Get your credit reports from each of the three bureaus first. You can get free copies at AnnualCreditReport.com. Check for mistakes. Wrong balances, accounts that aren't yours, or late payments that were on time but got reported wrong. Within 30 to 45 days, disputing false information and having it fixed typically improves your score.

Reduce the amount owed on your credit cards. The quickest lever you can pull is this one. There is a discernible difference when your usage falls below 30%, and it is much better when it falls below 10%. If you have several cards, start by concentrating on the ones that are closest to their limitations. In just a few billing cycles, AmeriSave borrowers who take this action prior to application frequently experience significant improvements.

Keep your old accounts open. The age of your credit card account improves your score even if you no longer use it. By lowering your total available credit, closing it shortens your average credit history and worsens your utilization.

In the months preceding your mortgage application, refrain from opening new accounts. Each new account reduces the average age of your accounts and generates a hard inquiry. Those two things are detrimental to you.

Ask someone in your family to register you as an authorized user if they have a credit card with a lengthy history of on-time payments and low usage. It's not even necessary to use the card. Your credit report typically includes the account history, which can raise your score by increasing your average account age and adding a good payment history. This is most effective when the card has a low balance and has been open for a number of years.

For each bill you have, set up autopay. One late payment can lower your credit score by 60 to 100 points, making late payments the most detrimental item on a credit report. Autopay eliminates the possibility of human error.

Before paying off a collection account that appears on your report, speak with a loan officer. Sometimes paying a collection decreases your score temporarily and modifies the date of your last activity. Depending on your particular circumstances, an experienced loan officer can advise you on whether to pay it, negotiate a deletion, or leave it alone.

Ask about a quick rescore if you're currently working with a lender and your score is only a few points below a higher rate tier. This is something that most individuals are unaware of. With this service, the lender notifies the credit bureaus directly of any recent changes, such as a paid-off credit card balance, and your report is updated in three to five business days as opposed to the customary thirty to sixty. This needs to go through the lender; you can't do it yourself. However, I have witnessed borrowers save actual money on their rate by surpassing important criteria. You'll be shocked at how frequently a few points separate one rate tier from another.

Common Credit Score Mistakes That Delay Closings

Your credit history is still important once you're in the middle of a mortgage application. I've witnessed closings fail or be delayed due to a borrower's actions that they were unaware would pose an issue. Things move quickly in the DFW market where I work, and you could lose the house you desired due to an unexpected credit issue.

One of the most frequent errors is applying for a new credit card. Perhaps you received a 20% discount on a large furniture purchase with your shop card. The lender will need to re-pull your credit and possibly re-underwrite the loan because that new account causes a hard inquiry and modifies your credit profile. Every borrower at AmeriSave is advised to avoid applying for any new credit between preapproval and closing day.

Another is using current credit cards to make significant purchases. A high debt appears on a mid-process credit check and affects your DTI ratio, even if you intend to pay the balance immediately.

Your application will be rejected if you co-sign for someone else's loan during the application process. Your responsibilities are immediately increased by that additional debt. Changing jobs might also be problematic if the new role has a different pay scale or a gap in employment history.

Underwriters are alerted when big amounts of money are transferred between accounts without a clear paper trace. They have to confirm where your money came from, and deposits that don't make sense drag things down. Maintain a clean banking record and keep track of any significant transfers.

The greatest error of all is undoubtedly failing to make a payment on any account during the loan application procedure. A single 30-day late payment on a credit card or auto loan might lower your credit score to the point that your loan program's minimum is reached or your rate tier is changed. Set reminders or automate all of your payments if you're juggling bills while purchasing a home. You shouldn't discover that your score suffered last month at the closing table.

The Bottom Line

Your credit score for a mortgage is one number, but it touches every part of the home buying experience. It affects the loans you qualify for, the rate you're offered, and how much money you'll pay over the life of your loan. The good news is that you have more control over this number than you probably think. Small, consistent moves like paying bills on time, keeping balances low, and checking your reports for errors can make a real difference. When you're ready to see where you stand, AmeriSave can help you take that first step with a quick online prequalification.

Frequently Asked Questions

The sort of loan you are seeking for will determine the minimum. You can put down 3.5% for 580 or 10% for 500 on an FHA loan. A minimum of 620 is required for the majority of conventional loans. While most lenders require a minimum of 580 to 640, there is no federal requirement for VA or USDA loans. Your rate will be greater and you will have more possibilities if your score is higher. Find out which programs are now appropriate for you by using AmeriSave to check your eligibility for FHA loans.

No, not at all. Examining your own score via AnnualCreditReport.com or a credit monitoring service is a gentle pull that has no effect on your score. When a lender checks your credit throughout the application process, it's a hard inquiry, and even they have a minor effect. Shopping for mortgage rates won't lower your credit score because credit scoring models combine inquiries about mortgages made within a 14- to 45-day period into a single hit.

It relies on your starting point and the factors lowering your score. Paying down large credit card debt might have an impact within one to two payment cycles. It may take 30 to 45 days to fix some of the mistakes in your report. Serious issues, such as a recent bankruptcy or foreclosure, take longer—sometimes years. Find out what influences your credit score and concentrate on the adjustments that will make the biggest difference in the shortest amount of time.

Indeed. One of the lowest down payment alternatives available is an FHA loan with only 3.5% down if your score is 580. You have full access to the loan. Compared to someone with a 740, your interest rate will be greater, but A reliable source of income, reasonable debt levels, and sufficient savings to meet closing costs are all prerequisites. You can begin your prequalification process online to find out where you stand, and AmeriSave works with borrowers of all credit levels.

The majority of mortgage lenders will utilize the average score from Equifax, Experian, and TransUnion. If you apply with a co-borrower, the lender will utilize the lower of the two middle scores. Although FICO 10T and VantageScore 4.0 are becoming more popular, the majority of lenders still utilize the Classic FICO versions 2, 4, and 5. Trended data, which monitors your credit behavior over the previous 24 months, is used by the more recent models. Learn more about your credit and mortgage preapproval to get an idea of how the process operates.

A complete preapproval requires a hard credit draw, which can temporarily lower your score by a few points. Prequalification typically has no effect on your score and is a light pull. The benefit of knowing exactly what you qualify for outweighs the modest decline from a hard inquiry, which returns in a few months nonetheless. You don't have to initiate contact when you have AmeriSave prequalification.

The savings may be substantial. The difference between a 6.5% and 7.25% rate on a $315,000 loan is almost $158 per month, or almost $56,880 over a 30-year mortgage. That difference may narrow or broaden based on the size of your loan and the distance between the rates. A 20-point improvement could even propel you into a higher rate category. Check out the mortgage rates AmeriSave is currently offering to see how far your score can take you.

Yes, but your options are limited. Instead of utilizing a credit score, some lenders use manual underwriting, which involves looking at your payment history for things like rent, electricity, and insurance. For certain FHA loans, manual underwriting is an option. It requires more time. There are more documentation obligations. Before applying, discuss ways to develop a scoreable history with an AmeriSave loan officer if you have a thin file.

Despite their differences, they are both significant. The lender can determine how reliable you have been with debt in the past by looking at your credit score. Whether you can afford the new mortgage payment in the future depends on your income. To make the cut, you need both pieces. You won't be able to obtain a large loan if you have a good score but a low income, and your alternatives will still be restricted if you have a high income but a poor score. To understand how your debt-to-income ratio functions, learn how lenders value it.

The lender may have to reevaluate your loan if your score declines between preapproval and closing. In certain situations, this can include a higher interest rate or other requirements. In the worst situation, you can totally lose their approval. Don't make big purchases, open new credit accounts, or co-sign for anyone else while your mortgage is being processed in order to safeguard your loan. See AmeriSave's advice on how to maintain a consistent credit score throughout the closing process for FHA customers with poor credit.
