Mortgage credit score requirements are not one number. They change with the transaction as much as the program — the same score that buys a primary residence may not take cash out of a rental, and a streamline refinance may not check it at all.
By Julia LuisMortgage Loan Officer · Mortgage-World.comRequirements tighten as the lender’s risk rises. Streamline refinances are the most forgiving (sometimes no credit qualification), then purchases (500–580 FHA, 620 conventional), then cash-out, then second homes and HELOCs, then investment property, DSCR and jumbo at the strictest end. Lenders qualify on your middle score.
The rule nobody explains
Requirements Change With the Transaction, Not Just the Program
Most articles about credit stop at “580 for FHA, 620 for conventional.” That is the purchase answer, and it is only part of the picture. Mortgage credit score requirements move with the lender’s risk, and risk depends on what you are doing as much as which program you use.
Lowering your rate on a loan you already have is the most forgiving transaction there is — an FHA Streamline or VA IRRRL can proceed with no appraisal, reduced documentation, and in some versions no credit qualification at all. Buying a primary residence sits next. Cash-out refinancing is stricter, because you are increasing what is owed against the house. A second home is stricter than a primary. Investment property is strictest of all.
A 640 that buys a primary residence comfortably may not take cash out of a rental. Same borrower, same score, different answer.
By program
Mortgage Credit Score Requirements by Loan Type
| What you are doing | Typical floor | Notes |
|---|---|---|
| FHA Streamline / VA IRRRL | Often none | Some versions are non-credit-qualifying |
| FHA purchase | 580 (500 with 10% down) | Pricing barely changes with score |
| VA purchase | No published minimum | Lenders typically want 580–620 |
| USDA | 640 typical | Automated approval threshold |
| Conventional purchase | 620 | Pricing improves in tiers to 740 |
| Cash-out refinance | 620 conventional, lower on FHA | Lower LTV ceiling than rate-and-term |
| HELOC / second lien | Usually 660–680 | Second-lien position raises the bar |
| DSCR investment | Often 620–660 | Property rent qualifies, not your income |
| Non-QM | Varies widely | Credit, reserves and property carry the file |
Two mechanics apply everywhere. Lenders pull all three bureaus and qualify you on the middle score. With two borrowers, most programs then use the lower of the two middle scores — which is why a strong co-borrower does not always rescue a weak one.
The components
What the Score Is Actually Made Of
Two categories are 65% of the score, and one of them resets every month.
Payment history is the largest piece and the slowest to change — only time heals it. Amounts owed is nearly as large and is the fastest thing you can move, because balances re-report monthly. Length of history rewards patience and punishes closing old accounts. New credit and credit mix make up the rest.
That structure explains why credit advice that works is boring: pay balances down, leave old accounts open, make every payment on time, and stop opening things.
Sixty days
Moving Your Score Before You Apply
- Pay revolving balances below 30% of their limits, starting with the cards closest to maxed rather than the largest balances. This is the single fastest lever.
- Do not close old accounts. You lose the history and the available limit, which pushes utilisation up.
- Pull all three reports and read them at AnnualCreditReport.com, free. Errors come off, and they are common.
- Do not pay old collections yet. On some scoring models paying one restarts its clock. Ask first — the order matters.
- Open nothing new. A car loan mid-process changes the file that was approved.
The CFPB publishes the same guidance for free, which is worth knowing before paying a credit-repair company that charges up front.
No score at all
Credit Score Requirements With a Thin File or a Past Credit Event
A thin file is not bad credit. FHA allows a manually underwritten loan built on non-traditional credit — twelve months of documented rent plus utilities, insurance, phone or tuition. It takes more paperwork and the debt ratios are tighter, but it works.
After a bankruptcy, foreclosure or short sale, the question is usually seasoning rather than score. Waiting periods differ by program and by event, and they run from as little as one year on some Chapter 13 files to several years on a conventional foreclosure. Non-QM programs exist specifically to shorten those windows at a price. If credit is the obstacle to a purchase in New Jersey, our guide to buying with damaged credit covers the repair path; if you are already a homeowner, see refinancing options below 620.
Score versus price
Above the Minimum: What a Higher Credit Score Buys
Above the floor, your score stops deciding whether you are approved and starts deciding what it costs. Conventional pricing moves in tiers — 620, 640, 660, 680, 700, 720, 740 — and each step improves the rate and the mortgage insurance factor. Being three points below a tier is the highest-return credit work available to you.
FHA is the deliberate exception: its pricing barely moves with score and its mortgage insurance is identical at 580 and 780. That is exactly why FHA is the right answer for bruised credit, and why a borrower with excellent credit is usually better off conventional. Buying your first home? The purchase-specific version of this is in our first-time buyer credit guide.
- The floor moves with the transaction: streamline refinance is loosest, investment property strictest.
- Lenders use your middle score, and the lower borrower’s middle score when there are two of you.
- Amounts owed is 30% of the score and re-reports monthly — the fastest lever you have.
- Do not close old accounts, and do not pay old collections before a loan officer reads the report.
- A thin file is workable: twelve months of rent and utilities can build non-traditional credit.
- Above the floor, score sets price, not permission — except on FHA, where pricing barely moves.
Common questions
Questions About Mortgage Credit Score Requirements
What is the lowest score that can get any mortgage?
FHA and VA files can be placed down to 500 FICO with a larger down payment, and some streamline refinances do not require a credit qualification at all. Below 500 on a purchase there is no program, and the work becomes credit repair first.
Why is the score requirement higher for a rental property?
Because default risk is higher on a property the borrower does not live in. The same logic explains why cash-out is stricter than rate-and-term and why second homes sit between primary and investment.
Does a DSCR loan check my credit?
Yes, though it does not check your income. The property’s rent does the qualifying, but the lender still prices off your score, typically starting somewhere in the low-to-mid 600s.
Is the score lenders see the same one I see on my banking app?
Usually not. Consumer apps often show VantageScore or a FICO version different from the mortgage-specific models lenders pull. Differences of 20 to 40 points are common and not an error.
How long do negative items stay on my report?
Most late payments and collections report for seven years, and bankruptcies for seven to ten depending on chapter. Their weight fades well before they fall off, so a two-year-old late hurts far less than a recent one.
Can I refinance to a better rate once my score improves?
Yes, and it is one of the more common reasons to refinance. Run the break-even first: closing costs divided by monthly savings gives the months to recover the cost.
