There is no single credit score required to buy a house in Florida. 580 is an important FHA benchmark, while 620 remains a common conventional reference point for manually underwritten fixed-rate loans. VA and USDA do not set a universal program minimum. Your actual approval depends on the loan program, down payment, debt-to-income ratio, cash reserves, credit history, and underwriting result.
That distinction matters because a borrower with a 640 score can have a stronger mortgage file than someone with a 700 score carrying too much debt and too little cash.
Credit Score Requirements by Mortgage Program
The fastest way to understand where you stand is to look at the major loan programs separately.
Here is the current picture for Florida homebuyers.
| Loan Program | Credit Score Guideline | Key Point |
| FHA | 580+ | Eligible for maximum FHA financing |
| FHA | 500–579 | Maximum 90% LTV, which means at least 10% down |
| Conventional, manual fixed-rate | 620 | Fannie Mae minimum for manually underwritten fixed-rate loans |
| Conventional, manual ARM | 640 | Fannie Mae minimum for manually underwritten adjustable-rate loans |
| Conventional through DU | No universal Fannie Mae minimum | Automated underwriting evaluates the entire file |
| VA | No VA-set minimum | Lender underwriting standards still apply |
| USDA Guaranteed | No USDA-set minimum | Creditworthiness and full underwriting determine approval |
These are program rules and underwriting benchmarks, not automatic approval scores. Atlantic Trust Mortgage reviews the complete borrower profile before determining which financing route makes sense.
FHA Loans: 580 Is the Main Benchmark
FHA gives buyers with lower credit scores a clear path into mortgage financing.
For current FHA transactions with case numbers assigned before January 1, 2027:
- 580 or higher: eligible for maximum FHA financing.
- 500 to 579: limited to 90% loan-to-value, meaning at least 10% down.
- Below 500: not eligible for FHA-insured financing under the standard rule.
That makes 580 an important number, but it does not mean every borrower with a 580 score receives an approval.
Income, debt, employment, reserves, payment history, and the underwriting findings still matter.
Example
Suppose you are buying a Florida home for $350,000.
At 580 or above, FHA maximum financing can permit a base down payment of 3.5%, or:
$350,000 × 3.5% = $12,250
With a score between 500 and 579, the maximum LTV is 90%, so the minimum down payment becomes:
$350,000 × 10% = $35,000
That is a $22,750 difference in required down payment before closing costs and prepaid expenses are considered.
Conventional Loans: 620 Is No Longer the Whole Story
This is where a lot of mortgage articles are now outdated.
As of November 2026, Fannie Mae states that Desktop Underwriter, or DU, does not impose a universal minimum credit score on DU loan casefiles. DU evaluates credit along with debt-to-income ratio, reserves, loan-to-value, occupancy, property type, loan purpose, and other risk factors.
For manually underwritten Fannie Mae loans, the current minimums are more straightforward:
- 620 for fixed-rate mortgages
- 640 for adjustable-rate mortgages
So saying, “You need a 620 to get a conventional mortgage,” is too simplistic.
A stronger way to look at it is this: 620 remains a useful conventional benchmark, but automated underwriting can evaluate a borrower more broadly than one score alone.
Atlantic Trust Mortgage can review how your score interacts with the rest of your conventional loan file rather than rejecting a scenario based on one number.
VA Loans Do Not Have a VA Minimum Credit Score
The Department of Veterans Affairs does not establish a minimum credit score for the VA home-loan program.
VA’s own buyer guidance states this directly. Lenders still evaluate credit, income, debts, and overall repayment risk, and individual lender standards can be stricter than VA’s underlying program rules.
That distinction matters.
A veteran should not assume that missing a lender’s preferred credit score automatically means VA financing is unavailable.
The better question is whether the full file works under VA guidelines and the lender’s underwriting standards.
USDA Also Has No Universal Program Minimum
USDA’s Single Family Housing Guaranteed Loan Program also states that it has no program-wide credit score requirement.
Applicants must still demonstrate the willingness and ability to manage debt, and the loan goes through lender and USDA underwriting requirements.
USDA loans can provide 100% financing for eligible borrowers purchasing qualifying properties, making the program worth reviewing when the home and borrower meet USDA requirements.
Again, the lesson is simple: do not eliminate yourself because of a credit-score number you found in an old article.
How Mortgage Lenders Actually Use Your Credit Score
Your credit score is one part of the underwriting decision.
Automated underwriting systems evaluate the score alongside factors such as:
- Payment history
- Revolving credit utilization
- Late payments
- Collections
- Installment debt
- Foreclosures
- Recent credit inquiries
- Debt-to-income ratio
- Loan-to-value ratio
- Cash reserves
- Property type
- Occupancy
- Income stability
Fannie Mae’s DU specifically evaluates credit and non-credit risk factors together rather than treating one number as the entire approval decision.
That explains why two borrowers with the same credit score can receive very different results.
A 680 Score With Strong Finances Can Beat a 720 With Heavy Debt
Consider two Florida buyers.
Buyer A
- Credit score: 680
- Monthly qualifying income: $9,000
- Monthly recurring debts: $900
- Down payment: 10%
- Cash remaining after closing: $25,000
- Clean recent payment history
Buyer B
- Credit score: 720
- Monthly qualifying income: $9,000
- Monthly recurring debts: $3,500
- Down payment: 5%
- Cash remaining after closing: $2,000
Buyer B has the higher score.
Buyer A, however, brings substantially lower monthly debt, more equity, and stronger reserves.
That is why Atlantic Trust Mortgage looks at the mortgage file as a whole rather than treating the highest score as the automatic winner.
How DTI Ratio Impacts Mortgage Approval
What Credit Score Does a Mortgage Lender Actually Use?
Mortgage lenders generally obtain scores from the major credit repositories and apply program-specific rules to determine the qualifying score.
Under current Fannie Mae guidance, when three scores are available for one borrower, the middle score is used as that borrower’s representative score. If only two scores are available, the lower score is used.
For example:
Equifax: 741
Experian: 704
TransUnion: 676
The representative score is 704, not 741 and not an average of the three.
For multiple borrowers, additional loan-level rules apply.
This is one reason a free consumer credit score from a banking app should not be treated as your final mortgage score.
Does a Higher Credit Score Still Matter?
Absolutely.
Qualifying for a mortgage and qualifying on strong terms are two different things.
A higher credit score can strengthen the overall file and influence:
- Interest-rate pricing
- Conventional loan-level pricing adjustments
- Mortgage insurance
- Down-payment flexibility
- Automated underwriting results
- Available lender options
A borrower who qualifies at 620 should not assume there is no benefit to reaching 680, 700, or 740 before locking a mortgage.
The right move depends on how much the improvement changes the actual loan economics.
What Hurts Your Mortgage Credit Profile Most?
The biggest mistakes tend to happen right before or during the mortgage process.
Missing a payment
A new late payment is far more serious than an old issue that has already aged.
Keep every account current while preparing to buy.
Running credit cards close to their limits
High revolving utilization can reduce a credit score even when payments are made on time.
If you owe $8,500 on a card with a $10,000 limit, that card is at 85% utilization.
Reducing the balance can improve the profile significantly.
Opening new debt before closing
A new car payment, personal loan, or large credit-card balance changes your monthly obligations.
That can hurt both credit and DTI.
Do not finance furniture, a vehicle, or major purchases simply because you already received a preapproval.
Closing old credit accounts without a reason
Closing an established account can change available credit and utilization.
Do not make major credit changes during a mortgage application without discussing them with your mortgage professional first.
What If Your Score Is Below the Number You Expected?
Do not start randomly paying accounts or disputing items.
Start with the mortgage math.
Atlantic Trust Mortgage can review:
- The scores being used for mortgage qualification
- The loan programs available
- Your debt-to-income ratio
- Current revolving balances
- Required cash to close
- Available reserves
- Whether improving the score materially changes the financing terms
Sometimes paying down one credit card is useful.
Sometimes keeping that cash for closing and reserves creates a stronger mortgage file.
The correct answer comes from running the numbers first.
What Credit Score Should You Aim for Before Buying in Florida?
If you want a practical target rather than a bare-minimum rule, aim to build the strongest overall file possible.
A score in the high 600s or 700s generally gives a borrower more room than trying to qualify at a program’s lower boundary.
But do not delay a home purchase simply because your score is not 740.
A borrower with:
- Stable income
- Manageable debt
- Documented assets
- Strong recent payment history
- Adequate cash to close
can have workable mortgage options well below that level.
The first step is finding out what your actual mortgage profile supports.
Find Out What Your Credit Profile Qualifies for in Florida
Your credit score matters, but it does not make the mortgage decision by itself.
Atlantic Trust Mortgage works with Florida buyers across Conventional, FHA, VA, USDA, Jumbo, and first-time homebuyer financing. Instead of guessing which credit-score rule applies to you, the team can review your income, debt, assets, down payment, credit profile, and property goals together.
That gives you a much more useful answer than “your score is good” or “your score is too low.”
