The familiar statement “you need a 620 for a conventional mortgage” is now too broad. Automated underwriting by the two major Enterprises has moved away from a single universal floor for Accept/Approve-style outcomes, while manual underwriting and lender overlays can still use explicit score requirements.
Credit score also affects more than approval. Pricing, mortgage insurance, down payment, reserve requirements, and product availability can change as the credit profile strengthens or weakens.
Key Takeaways
- No universal mortgage minimum exists: Program, underwriting path, lender overlay, and borrower profile all matter.
- Fannie Mae DU no longer has the old fixed 620 minimum: The requirement was removed for new casefiles created on or after Nov. 16, 2025.
- Freddie Mac LPA Accept mortgages do not require a minimum Indicator Score: Manual and non-LPA rules can differ.
- FHA still uses 580/500 financing thresholds: Scores at or above 580 can qualify for maximum 96.5% purchase LTV; 500–579 is limited to 90% LTV under current handbook rules.
- Lenders may be stricter: A program’s baseline eligibility does not force every lender to approve the loan.
Why the Conventional 620 Rule Changed
Fannie Mae updated Desktop Underwriter to remove the fixed 620 representative-score requirement for new casefiles created on or after Nov. 16, 2025. DU now relies on its broader credit-risk assessment rather than that single minimum.
Freddie Mac’s current Guide states that a minimum Indicator Score is not required for Loan Product Advisor Accept mortgages because LPA has determined the borrower’s credit reputation and mortgage product are acceptable.
Neither change means credit score stopped mattering. Scores remain part of credit reporting and risk assessment, can affect pricing, and may be required in manual or specialized underwriting.
FHA Credit-Score Thresholds
Current FHA policy links the Minimum Decision Credit Score to maximum financing. A score at or above 580 can be eligible for maximum purchase financing of 96.5% LTV, while a score from 500 through 579 is limited to 90% LTV.
Those are FHA insurance eligibility parameters, not approval guarantees. Income, DTI, property, documentation, mortgage insurance, prior federal debt, and lender standards still apply.
Manual underwriting can also introduce specific ratio rules and compensating-factor requirements.
VA and USDA Do Not Reduce the Decision to One National Score
VA does not establish one statutory minimum credit score for every guaranteed loan; lenders evaluate credit under VA requirements and can set overlays. USDA guaranteed-loan underwriting likewise depends on program rules and lender/automated underwriting rather than a single consumer-facing score that applies to every file.
Borrowers should therefore ask a lender for the actual score policy tied to the specific program and underwriting path instead of relying on a generic comparison chart.
Credit Score Affects Mortgage Price
Approval is only the first threshold. Conventional loan pricing can change with credit-score bands, LTV, occupancy, property type, and other risk characteristics.
Mortgage-insurance pricing can also respond to credit profile. A borrower approved at a lower score may therefore face a higher rate, higher PMI cost, or less favorable combination of points and credits than a stronger applicant.
Review APR and interest rate together when comparing those offers.
Down Payment and Credit Interact
More cash down can reduce LTV and sometimes improve pricing or program eligibility. It does not automatically compensate for every credit weakness.
FHA’s 500–579 score band is a clear example: maximum LTV is 90%, which effectively requires at least 10% equity contribution on a standard purchase before other transaction details.
Use the homebuying cash framework before committing all available savings solely to overcome a credit threshold.
What Lenders Review Beyond the Score
- Payment history and recent delinquencies
- Revolving utilization and total debt
- Collections, charge-offs, bankruptcy, or foreclosure history
- Debt-to-income ratio
- Income stability and documentation
- Assets and reserves
- Property and transaction risk
A score is a summary signal, not the entire mortgage file. Automated underwriting can accept combinations that a simple score table would classify poorly, while a nominally high score does not cure unverified income or an ineligible property.
Mortgage Shopping Can Create Multiple Inquiries
Rate shopping often requires several lenders to access credit. Scoring models commonly deduplicate qualifying mortgage inquiries within a defined shopping window, but the exact window depends on the model.
FICO has described 14-day and 45-day mortgage-shopping windows across different versions, while VantageScore 4.0 uses a 14-day deduplication period. Shop in a concentrated period rather than assuming unlimited inquiries will be treated as one.
How to Improve the File Before Applying
- Check all three credit reports for genuine errors.
- Bring past-due accounts current when possible.
- Reduce revolving balances without draining closing reserves.
- Avoid unnecessary new debt before underwriting.
- Keep on-time history building over time.
- Compare multiple loan programs rather than forcing one product.
Loan term can change affordability after approval. A 15-year-versus-30-year comparison can clarify the payment trade-off, while PMI deserves separate review when lower-down-payment conventional options are on the table.
Frequently Asked Questions (FAQs)
Do I still need a 620 score for a conventional mortgage?
Not as a universal automated-underwriting rule. Fannie Mae DU and Freddie Mac LPA Accept mortgages no longer use that blanket minimum, though lender overlays and other underwriting paths can.
What score does FHA require for 3.5% down?
Current FHA policy generally requires a minimum decision credit score of at least 580 for maximum 96.5% purchase LTV, subject to full eligibility and lender requirements.
Can I get an FHA loan with a 500 score?
FHA policy permits the 500–579 band only up to 90% LTV, but individual lenders may set higher minimums.
Does a higher score always mean approval?
No. Income, DTI, assets, property, documentation, and other underwriting factors still matter.
Can mortgage shopping hurt my score?
Hard inquiries can affect scoring, although qualifying mortgage inquiries within model-specific shopping windows are commonly grouped for scoring purposes.
