What Credit Score Do You Need for a Mortgage?

Why Your Credit Score Matters So Much

Your credit score is one of the most influential numbers in the entire mortgage process. It determines which loan programs you qualify for, how much down payment you may need, and — critically — what interest rate you'll pay. A difference of just 50-100 points can shift your rate enough to change your monthly payment by hundreds of dollars.

The Five Factors That Make Up a FICO Score

Mortgage lenders almost universally pull FICO scores (specifically older FICO versions like FICO 2, 4, and 5 for the three major bureaus), so it helps to understand what actually drives the number. FICO scores are built from five weighted categories:

• Payment history (about 35%): The single largest factor. Late payments, collections, charge-offs, foreclosures, and bankruptcies all weigh heavily here, and their impact fades only gradually over several years. A single 30-day-late payment can drop a strong score by 60-100 points.
• Credit utilization (about 30%): The percentage of your available revolving credit you’re currently using. Scoring models reward keeping balances low relative to limits — both on individual cards and in aggregate — and this factor can swing quickly since it’s based on your most recent reported balances.
• Length of credit history (about 15%): How long your accounts have been open, including the age of your oldest account and the average age across all accounts. This is one reason mortgage advisors caution against closing old credit cards before applying.
• New credit (about 10%): Recently opened accounts and hard inquiries. Opening several new accounts in a short window signals increased risk to scoring models, even if each account is managed responsibly.
• Credit mix (about 10%): Having experience managing different types of credit — revolving accounts like credit cards alongside installment loans like auto loans or student loans — contributes modestly to the score.

For mortgage purposes, the first two factors — payment history and utilization — deserve the most attention in the months before applying, since they respond fastest to disciplined changes in behavior and carry the heaviest weight.

Credit Score Tiers Lenders Use

While every lender sets its own thresholds, most mortgage pricing follows a similar pattern of tiers:

These ranges are general guidance, not universal rules — actual cutoffs vary by lender, loan program, and current market conditions.

Minimum Credit Scores by Loan Type

• Conventional loans: Typically require a minimum score around 620, though the best pricing is reserved for scores of 740 and above.
• FHA loans: Allow a score as low as 580 with 3.5% down, or as low as 500-579 with at least 10% down, making FHA one of the most accessible options for buyers rebuilding credit.
• VA loans: Have no official minimum score set by the VA itself, but individual lenders commonly apply their own overlay, often in the 580-620 range, since the VA guarantee doesn't eliminate the lender's own risk assessment.
• USDA loans: Most lenders look for a score of at least 640 for streamlined underwriting, though exceptions exist.

How Credit Score Drives Your Interest Rate

Lenders use a system often called risk-based pricing, built around loan-level price adjustments (LLPAs). In simple terms, your credit score (combined with your down payment size and loan type) is mapped to a pricing grid that adds or subtracts fractions of a percentage point from your base rate. Lower scores and lower down payments generally mean larger upward adjustments — meaning a higher rate or higher upfront fees (points) to buy down that rate.

This is why two borrowers applying for the exact same loan amount can receive noticeably different rates purely based on credit score. Over a 30-year term, even a 0.5% rate difference can add up to tens of thousands of dollars in extra interest — see the Amortization Calculator to visualize the long-term cost of a higher rate.

To make this concrete, here’s an illustrative example of how loan-level price adjustments might translate into an actual rate on a $350,000, 30-year conventional loan with 20% down. These figures are for illustration only — actual pricing changes daily with market conditions and varies by lender:

Rather than a higher rate, some borrowers are instead offered the same rate with additional upfront points charged at closing to offset the risk adjustment — the lender may present it either way. Either version has the same effect: lower scores cost more, whether paid monthly through a higher rate or upfront through points. On our $350,000 example, the gap between the top tier and the 620-639 tier is roughly 1 to 1.5 percentage points, which alone can mean $200-350 more in monthly payment and well over $80,000 in additional interest across a 30-year term.

How to Improve Your Score Before Applying

1. Pay every bill on time. Payment history is the single largest factor in most credit scoring models.
2. Lower your credit utilization. Try to keep credit card balances below 30%, and ideally below 10%, of your available limit.
3. Don't open new credit accounts before applying. New accounts and hard inquiries can temporarily lower your score and shorten your average account age.
4. Don't close old accounts either. Closing a long-standing account can shorten your credit history length and raise your utilization ratio.
5. Check your credit report for errors. Incorrect late payments or accounts that aren't yours can be disputed and removed, sometimes boosting your score meaningfully.
6. Avoid large new purchases on credit in the months leading up to your mortgage application and even between pre-approval and closing.

A 3-6 Month Plan to Raise Your Score Before Applying

Because payment history and utilization respond relatively quickly to changed behavior, a focused 3-6 month runway before applying can meaningfully move your score, sometimes enough to jump a full pricing tier. A practical timeline looks like this:

6 Months Out

Pull your full credit reports from all three bureaus (available free weekly at annualcreditreport.com) and dispute any inaccurate late payments, accounts that aren’t yours, or outdated negative items still showing. Stop applying for new credit of any kind — cards, auto loans, "buy now pay later" plans — since each hard inquiry and new account can ding your score and shorten your average account age.

3-4 Months Out

Aggressively pay down revolving balances, prioritizing the cards closest to their limit first, since utilization is calculated both per-card and in aggregate. Getting a single maxed-out card down to under 30% utilization can produce a fast, noticeable score bump when the next statement reports to the bureaus. Keep every account open and continue paying everything on time — this is not the time to consolidate or close cards.

1-2 Months Out

Freeze your spending on credit as much as possible so your reported balances stay low right when the lender pulls your score. Avoid co-signing for anyone else’s loan, and hold off on any large purchases — even a big-ticket item bought with cash can matter if it depletes reserves lenders want to see. Get pre-approved so you know your actual score tier and can address any last surprises before shopping for a home.

Between Pre-Approval and Closing

Change nothing. Lenders commonly re-pull credit or verify employment shortly before closing, and a new car loan, furniture financing, or a big jump in credit card balances during this window can change your debt-to-income ratio or score enough to delay or derail closing entirely.

Joint Applications and Co-Borrowers With Different Scores

When two or more borrowers apply together — commonly spouses or partners — lenders don’t average the credit scores. Instead, for each applicant, the lender typically takes the middle of that person’s three bureau scores (or the lower of two if only two bureaus report), and then uses the lowest of the applicants’ representative scores to price and qualify the loan. This is sometimes summarized as the "lower-middle score" rule.

For example, if one co-borrower has scores of 780/770/760 (middle: 770) and the other has scores of 640/630/610 (middle: 630), the loan is priced using 630 — not an average of the two, and not the higher applicant’s score. This can come as an unwelcome surprise to couples who assumed a strong score on one side would offset a weaker score on the other.

Because of this rule, some couples consider a few strategies:

• Apply with only the stronger-credit spouse if their income alone is sufficient to qualify for the needed loan amount — this uses only that person’s score, though it also means only their income counts toward qualification.
• Spend a few months improving the weaker score before applying jointly, using the same techniques above, since even a modest improvement in the lower score can shift the loan into a better pricing tier.
• Compare both scenarios with a loan officer, since the answer depends on whether the stronger-credit spouse’s income and debt-to-income ratio can support the loan alone.

This rule applies to co-borrowers on the same loan; it’s distinct from adding a non-occupant co-signer, which some loan programs allow specifically to boost qualifying income or compensate for a thinner credit file.

Shopping for a Mortgage Without Hurting Your Score

It's smart to compare rates across multiple lenders, and credit scoring models are designed to accommodate this. Most models treat multiple mortgage-related inquiries made within a short window (commonly 14-45 days) as a single inquiry, so rate shopping within that window has minimal score impact.
