Mortgage Credit Score Requirements by Loan Type
Your mortgage credit score is one of the first things a lender looks at when you apply for a home loan.
It affects whether you qualify, which loan programs are available to you, and what interest rate you will pay for the life of the loan.
Most buyers know their credit score matters, but fewer understand the minimum thresholds by loan program, how the score affects pricing, or what steps will move the number before submitting an application.
🏡 How Lenders Use Your Mortgage Credit Score
When a lender pulls credit for a mortgage application, they request scores from all three major credit bureaus: Equifax, Experian, and TransUnion.
Each bureau may show a slightly different score based on the information in its file.
For most loan programs, the lender uses the middle of the three scores as the qualifying score.
If the scores are 640, 660, and 710, the qualifying mortgage credit score is 660.
When two borrowers apply together, the lender typically uses the lower of the two middle scores.
The lender reviews both scores, and the lower qualifying score drives eligibility and pricing.
If one person has a significantly lower mortgage credit score, it may affect which programs are available and what rate the loan is priced at.
Minimum Mortgage Credit Score by Loan Type
Every loan program has its own minimum mortgage credit score requirement, and each one treats the score differently when it comes to pricing.
FHA loans
- 580 or higher: qualifies for the minimum 3.5% down payment
- 500 to 579: may still qualify but requires a 10% down payment
- Below 500: not eligible under current guidelines
Many lenders in North Texas apply overlays above the FHA minimum and may require a 620 or higher score even though FHA technically allows 580.
Confirming the lender’s actual floor early avoids surprises.
Conventional loans
Conventional loans generally require a minimum mortgage credit score of 620, but the score does much more than determine eligibility.
It directly affects pricing through loan-level price adjustments.
A borrower with a 760 score and a borrower with a 640 score may both qualify for the same loan, but the borrower with the lower score will pay significantly more in either rate or fees.
VA loans
VA does not publish a minimum mortgage credit score at the agency level.
Individual lenders set their own minimums, and most require somewhere between 580 and 640.
VA residual income and overall financial picture can offset a lower score in some cases.
USDA loans
USDA loans generally require a minimum mortgage credit score of 640 for automated underwriting approval.
Scores below 640 may still be eligible through manual underwriting but require a stronger overall financial profile.
🔍 How Your Score Affects Your Rate
Your mortgage credit score directly affects pricing, and the difference between tiers can be significant on a conventional loan.
Fannie Mae and Freddie Mac use loan-level price adjustments tied to both credit score and loan-to-value ratio.
As the score drops, the adjustment increases, meaning the borrower pays a higher rate or more in upfront fees.
General conventional pricing tiers by mortgage credit score:
- 760 and above: best available pricing
- 740 to 759: minimal adjustment
- 720 to 739: modest adjustment
- 700 to 719: noticeable adjustment
- 680 to 699: meaningful adjustment
- 660 to 679: significant adjustment
- 640 to 659: substantial adjustment
- Below 640: highest adjustment tier, if eligible at all
The difference between a 680 and a 760 mortgage credit score on a $350,000 conventional loan can translate to thousands of dollars over the life of the loan.
What Makes Up the Score
FICO scores, which are the most commonly used in mortgage underwriting, are calculated based on five factors:
- Payment history (35%): On-time payments are the single biggest factor. Late payments, collections, and charge-offs have the most negative impact.
- Amounts owed (30%): Credit utilization makes up a large portion of the score. Lower utilization generally produces a higher score.
- Length of credit history (15%): Longer history with consistent behavior tends to support a higher score.
- Credit mix (10%): A mix of revolving accounts and installment accounts can support the score.
- New credit (10%): Opening multiple new accounts in a short period can temporarily lower the score.
Payment history and credit utilization have the most immediate impact for buyers focused on improving their mortgage credit score before applying.
📈 How to Improve Your Mortgage Credit Score
Most credit improvements take time, which is why starting the review process several months before applying produces the best results:
- Pay every bill on time without exception in the months leading up to the application
- Pay down revolving balances, particularly credit cards, to below 30% of each card’s limit
- Avoid opening new credit accounts before applying
- Avoid closing old accounts since length of credit history is a scoring factor
- Dispute any errors on the credit report immediately
- Keep existing accounts active with occasional small purchases paid in full
Dropping credit card utilization from 80% to 20% can meaningfully improve your mortgage credit score in a relatively short period.
Credit Events and Waiting Periods
Certain credit events create waiting periods before a buyer can qualify for specific loan programs.
Bankruptcy
- Chapter 7: FHA and VA require two years from discharge. Conventional requires four years. USDA requires three years.
- Chapter 13: FHA and VA may allow eligibility after one year of on-time plan payments with court approval. Conventional requires two years from discharge or four years from dismissal.
Foreclosure
- FHA: three years from completion date
- VA: two years from completion date
- Conventional: seven years, or three years with extenuating circumstances
- USDA: three years from completion date
Short sale or deed in lieu
- FHA: three years
- VA: two years
- Conventional: four years, or two years with extenuating circumstances
- USDA: three years
Meeting the waiting period does not automatically guarantee approval.
The mortgage credit score and overall financial profile still need to meet program requirements at the time of application.
🏡 Score and Down Payment Strategy
Mortgage credit score and down payment are connected in ways most buyers don’t consider before applying.
On a conventional loan, a higher down payment can partially offset a lower score in the pricing calculation because a lower loan-to-value ratio reduces the loan’s overall risk profile.
FHA financing may also cost less overall for buyers with scores in the 580 to 660 range than conventional, especially when conventional pricing adjustments at that score tier are significant.
A full comparison of FHA versus conventional for your specific score, down payment, and loan amount gives the most accurate picture.

Mistakes That Hurt Your Score Before Closing
Several common mistakes can lower a mortgage credit score at exactly the wrong time:
- Opening new credit cards or financing furniture before applying
- Co-signing on another person’s loan
- Missing a payment on any account close to the application date
- Closing old credit cards, which reduces available credit and can increase utilization
- Applying for multiple loans or credit products in a short window
✅ Mortgage Credit Score Checklist
Before applying:
- Pull all three credit reports and review for errors
- Identify the middle score from all three bureaus as the likely qualifying score
- Check which loan program’s minimum the score meets
- Pay revolving balances below 30% of each card’s limit
- Confirm no new accounts will be opened before closing
- Make every payment on time without exception
- If applying with a co-borrower, review both scores and understand how the lower score affects eligibility and pricing
- Consult with a lender about whether waiting to improve the score or proceeding now makes more financial sense
📣 Frequently Asked Questions (FAQs)
What mortgage credit score do I need to buy a house?
The minimum depends on the loan program. FHA loans allow scores as low as 580 for the minimum down payment option. Conventional loans generally require a minimum of 620. VA loans don’t have a published minimum, but most lenders require 580 to 640. USDA loans typically require a 640 for automated underwriting approval.
How much does my credit score affect my mortgage rate?
Significantly. On a conventional loan, the difference between a 640 score and a 760 score can translate to a meaningfully higher rate or upfront fees due to loan-level price adjustments. Comparing different score tiers with a lender shows the exact cost difference for a specific loan amount and down payment.
Can I get a mortgage with a 580 credit score?
Yes, through FHA financing with a minimum 3.5% down payment, assuming the lender does not apply a higher overlay. Some VA lenders also work with scores at that level.
How long does it take to improve a mortgage credit score?
It depends on the starting point and what needs to be addressed. Paying down credit card balances can show improvement within one to two billing cycles. More significant issues, like recent late payments or collections, may take several months to show meaningful improvement.
What happens if my co-borrower has a lower credit score?
The lender typically uses the lower of the two qualifying scores for eligibility and pricing decisions. A co-borrower with a significantly lower score can affect which loan programs are available and what rate the loan is priced at.
This is educational and not financial advice. Loan programs and guidelines can change. Talk with a licensed mortgage professional about your specific scenario.
