Most buyers walk into a mortgage conversation believing they need a 720 or 740 credit score before anyone will take them seriously. They do not. The average U.S. FICO score is 717, and the published floors for the four loan programs that handle the vast majority of American mortgages all sit well below that. FHA officially starts at 580 with the standard 3.5 percent down payment, and HUD policy allows scores as low as 500 with 10 percent down. The Department of Veterans Affairs sets no minimum at all; most VA lenders accept 580 to 620. USDA’s automated underwriting clears 640. Fannie Mae and Freddie Mac conventional loans typically start at 620.
That gap between the score buyers assume they need and the score the program will actually approve is the single most common reason a family postpones a home search by a year. A year of rent and a year of home-price appreciation usually cost far more than the rate or insurance penalty of buying at a lower band. This article maps every program’s real cutoff, shows where your score most likely sits on the FICO band map, breaks down what each band costs at the rate lock, and details the highest-leverage moves to climb one band before you apply if you genuinely need to.
What Credit Score Does Each Mortgage Program Actually Require?
Every loan program publishes a minimum, and every lender overlays its own number on top of that. Both numbers matter, but the published minimum is the floor the program itself will allow. Here is what each of the four core programs actually sets.
FHA: 580 with 3.5% Down, or 500 to 579 with 10% Down
HUD Handbook 4000.1 sets two FHA tiers. At 580 and above, the borrower qualifies for the standard 3.5 percent down payment. Between 500 and 579, the borrower must put 10 percent down. Below 500, the FHA program is not available. Most retail lenders apply an overlay around 620 or 640 because servicing FHA loans at the bottom of the credit band carries higher early-payment-default risk, but specialty FHA lenders still take 580 with documentation. The gap between two FHA lenders’ rate sheets at the exact same FICO score is often as large as a full credit band.
VA: No Program Minimum, but Lenders Set 580 to 620
The VA itself does not publish a minimum credit score. Every VA lender is free to set its own. In practice, the bulk of VA lenders draw the line at 580 or 620 because Automated Underwriting System approval and secondary-market sale pricing tighten quickly below 620. A small group of VA-specialty lenders will manually underwrite down to about 540 with strong compensating factors, such as twelve months of cash reserves or a debt-to-income ratio under 35 percent.
USDA: 640 Through Automated Underwriting, Lower with Manual Review
USDA’s Guaranteed Underwriting System, the GUS engine that nearly every USDA Guaranteed Loan runs through, asks for a 640 representative credit score. Below 640, the loan must be manually underwritten, which means a human underwriter reviews the full file and looks for compensating factors: stable employment, twelve months of clean rent payments, low debt-to-income, or reserves. Manual approval below 640 is possible but slower and far less common than the automated path.
Conventional: 620 for Fannie Mae and Freddie Mac
Both Fannie Mae and Freddie Mac accept 620 as the entry point for conventional purchase loans, including their first-time buyer programs HomeReady and Home Possible. The credit-pricing waterfall on conventional sits very differently from FHA, though. A 620 score on a conventional loan triggers significant loan-level price adjustments and a much higher private mortgage insurance premium than a 740 score on the same loan amount.
Those four numbers are the published floors. What an underwriter actually evaluates during pre-approval includes the floor plus debt-to-income ratios, employment continuity, asset reserves, and the credit history behind the score itself. The number is necessary, but it is rarely the only gate.
Where Does Your Credit Score Sit on the Buyer Map?
FICO publishes the score distribution every quarter. Knowing which band you sit in tells you which programs are realistically open before you ever pull a rate sheet. According to Experian’s most recent national credit data, the average FICO 8 score in the United States is 717, and the band distribution looks roughly like this:
- 800 and above (exceptional): roughly 21 percent of consumers. Best pricing on every program, easiest underwriting.
- 740 to 799 (very good): about 25 percent of consumers. Conventional pricing is best, private mortgage insurance is cheapest.
- 670 to 739 (good): about 21 percent of consumers. All four programs open with normal pricing; conventional PMI starts climbing below 740.
- 580 to 669 (fair): about 17 percent of consumers. FHA strong, VA viable, USDA possible with manual review, conventional possible at 620 but expensive.
- Below 580 (poor): about 16 percent of consumers. FHA at 10 percent down through specialty lenders; other programs effectively closed.
The most common mistake we see is a borrower sitting comfortably in the 670 to 739 band who assumes the conversation has to wait until they reach 740. It does not. Every program is open at 670. Score matters, but so does how your income shapes the same qualification math. The borrower whose score is 690 with a 32 percent debt-to-income ratio is almost always in a stronger position than the borrower whose score is 745 with a 48 percent debt-to-income ratio. Lenders weight both inputs.
What Does Each Credit Score Band Cost at the Rate Lock?
Two borrowers shopping the same Tuesday morning, on the same loan amount, with the same loan-to-value, can receive rate quotes 100 to 150 basis points apart purely because of credit score band. The mechanics are different for each program.
Conventional Loans: LLPAs Are Sharply Tiered
Fannie Mae and Freddie Mac price conventional loans using loan-level price adjustments, a published matrix that adjusts the rate based on credit score and loan-to-value. A 760 score on a 75 percent loan-to-value purchase carries an LLPA close to zero. A 660 score on the same loan-to-value carries an LLPA of roughly 1.50 points, which translates to about a 0.375 percent higher rate at no additional cost. On a $300,000 loan over 30 years, that is roughly $65 a month, or $23,400 over the life of the loan.
Private Mortgage Insurance Is Where Score Hurts the Most on Conventional
The bigger surprise on conventional loans is private mortgage insurance. PMI premiums are heavily tiered by credit score. A 760 borrower with 5 percent down might pay an annual premium of roughly 0.27 percent. A 620 borrower with the same 5 percent down can pay 1.50 percent or higher. On a $300,000 loan, that is the difference between about $68 a month and about $375 a month. PMI ends after the borrower reaches 78 percent loan-to-value, but the early years are where score has the most expensive impact.
FHA: Flat MIP Across All Scores
FHA charges a flat mortgage insurance premium regardless of credit band: 1.75 percent upfront and 0.55 percent annually on most 30-year loans with less than 5 percent down. That flat structure is exactly why FHA usually beats conventional for borrowers in the 620 to 679 band. The score-blind MIP saves real money compared to score-tiered conventional PMI. Above 740, conventional pricing usually wins again. What pushes a borrower’s interest rate above the published weekly average is usually some combination of credit band, debt-to-income, and loan-to-value, not just one factor.
VA: The Funding Fee Is Score-Independent
The VA funding fee depends on prior VA loan use and down payment, not credit score. A 620 VA borrower and a 760 VA borrower with the same usage history pay the same funding fee. Where the score still matters on VA is the base rate itself; a 760 VA borrower will receive a lower interest rate than a 620 VA borrower, but the spread is usually narrower than on conventional because secondary-market pricing for VA paper is more compressed.
How Can You Move Up a Band Before You Apply?
Moving from 660 to 700, or from 700 to 740, before locking a rate can pay for itself many times over. Most credit-band climbing comes from the same three or four moves, and most of them take 30 to 90 days, not a year.
Bring Revolving Utilization Below 30 Percent, Ideally Below 10 Percent
The single highest-leverage move is reducing the balance on revolving credit cards. FICO calculates utilization on the statement closing date, not the due date, so paying down balances a few days before the statement closes shows up in the next reported score. A borrower with five cards totaling $20,000 in available credit who carries $8,000 of revolving debt is sitting at 40 percent utilization. Bringing that to under $2,000 across all cards in a single statement cycle can move a score 20 to 40 points within 30 to 45 days.
Dispute Genuine Reporting Errors, but Carefully
Charged-off accounts with incorrect dates, paid collections still showing balances, and accounts that belong to someone else with a similar name are all common reporting errors that suppress scores. File disputes through each bureau’s online portal, attach documentation, and expect a 30 to 45 day cycle per dispute. The documents pre-approval actually needs from you include the credit report, so any dispute results need to land before the file goes to underwriting.
Use a Rapid-Rescore Through Your Lender
Rapid-rescore is a lender-initiated process that asks the credit bureaus to reprocess corrected trade lines or recent paydowns within three to seven business days, rather than waiting for the next reporting cycle. It typically costs $30 to $50 per trade line and is only available through an active mortgage application. The borrower cannot request it directly. Used well, rapid-rescore can move a borderline borrower from 615 to 625 in time to clear the conventional 620 cutoff before rate lock.
Do Not Open New Credit, Do Not Close Old Accounts, and Do Not Pay Off Old Collections Cold
Opening a new card pulls scores down through the hard inquiry and the lower average account age. Closing a long-held card reduces total available credit and worsens utilization. Paying off an old collection without negotiating a goodwill removal in writing can actually wake up a dormant trade line and restart the seven-year reporting clock. Each of these is a recoverable mistake, but every one of them slows the closing timeline by at least a credit reporting cycle.
Frequently Asked Questions About Credit Score and Mortgage Approval
What credit score do you need to buy a house?
The floor depends on the loan program. FHA accepts 580 with 3.5 percent down, or 500 to 579 with 10 percent down. VA sets no minimum but most VA lenders require 580 or 620. USDA’s automated underwriting system clears 640. Conventional Fannie Mae and Freddie Mac loans typically start at 620. Lenders often apply their own overlays on top of these program floors.
Can you buy a house with a 580 credit score?
Yes, primarily through FHA with 3.5 percent down. Some VA lenders also accept 580, and a few specialty USDA lenders will manually underwrite at that score. Conventional is generally not available at 580. Expect a higher interest rate and, on conventional, a higher PMI premium than a borrower 100 points higher would pay.
Will a 620 credit score get a conventional mortgage?
Technically yes. Fannie Mae and Freddie Mac both accept 620. But conventional private mortgage insurance is sharply tiered by score, so a 620 borrower pays roughly five to six times the PMI of a 760 borrower on the same loan. At 620, the monthly cost of FHA often beats the monthly cost of conventional even after FHA’s flat 0.55 percent MIP.
Does a VA loan have a minimum credit score?
The Department of Veterans Affairs itself sets no minimum. Every VA lender sets its own. Most VA lenders draw the line at 580 or 620. A small group of VA-specialty lenders go down to about 540 with manual underwriting and compensating factors such as significant cash reserves and a low debt-to-income ratio.
What credit score is needed for a USDA loan?
USDA’s Guaranteed Underwriting System asks for a 640 representative credit score for an automated approval. Below 640, the loan can be manually underwritten if the borrower shows compensating factors such as a low debt-to-income ratio, twelve months of stable rent payments, or significant reserves. Manual approval below 640 is possible but takes longer.
How long does it take to raise your credit score before buying?
Paying down revolving balances below 30 percent utilization usually shows up in 30 to 60 days. Disputing legitimate errors takes 30 to 90 days per dispute cycle. Recovering from a 30-day late payment takes 12 to 24 months for the score impact to fade. Score improvements over 100 points typically require 12 to 24 months of consistent on-time payments and reduced balances.
Should you pay off all your debt before applying for a mortgage?
Not necessarily. Paying down revolving credit card balances usually helps both the score and the debt-to-income ratio. Paying off installment loans like car loans or student loans rarely moves the score much and can hurt the application if it drains the cash reserves needed for down payment, closing costs, and post-closing reserves. Old collections in particular should not be paid off without first speaking with the loan officer, because cold payment can restart the reporting clock and damage the score.
Should You Apply Now or Wait to Raise Your Score?
The honest answer is that it depends on how close you are to the next band cutoff and how long the climb will take. A borrower sitting at 615 who can pay one card balance down to under 10 percent utilization and clear 625 in 30 to 45 days should usually wait those few weeks. A borrower at 710 who would need another 12 months of clean activity to reach 740 should almost always start the conversation now; the cost of a year of rent, plus another year of price appreciation, almost always exceeds the rate-and-PMI savings of waiting for the next band. Walk through your real qualification picture with a Fellowship loan officer before deciding to delay; an honest review of your file will tell you which path is actually cheaper.
