A 520 credit score puts you in a narrow slice of the mortgage market. Plenty of loan officers will take your application and then ghost you two days later when the automated underwriting system spits back a denial. The lenders that do work with 520 files are real, but there are maybe a dozen of them worth your time, and the terms they offer vary more than most borrowers expect.
Here’s what the numbers actually look like, which programs will consider you, and how to make a 520 file look as strong as it can before you pay for an appraisal.
Where a 520 score stands with each loan program
Credit floors aren’t secrets. Every government-backed program publishes a minimum, and then individual lenders layer their own requirements on top. That second layer is what kills most 520 applications.
- Conventional (Fannie Mae and Freddie Mac): 620 minimum, full stop. At 520 you’re locked out no matter how much you put down.
- FHA: 500 minimum, but only with 10% down. Between 500 and 579, the 3.5% down option disappears. This is the main door for a 520.
- VA: No official credit floor, but most VA lenders overlay at 620 and a few go to 580. A 520 VA loan requires a lender with zero overlay plus strong compensating factors.
- USDA: Generally 640 for automated approval. Manual underwriting can go lower, but 520 is a long shot outside a handful of rural portfolio lenders.
- Non-QM and portfolio lenders: Possible, usually with 20% to 30% down and a rate two to three points above market.
FHA at 520: the 10% down rule and the overlay problem
FHA itself will insure a loan to a borrower with a 500 FICO. The catch is that FHA doesn’t lend money. Banks and mortgage companies do, and they can set stricter rules whenever they want. Chase, for example, has historically wanted 620 or better on FHA. So has Wells Fargo. That’s why a borrower with a 520 gets told “FHA won’t work for you” by one lender and approved by another three miles away.
Lender overlays to ask about directly
Before you fill out anything, ask one question: “What is your minimum FICO for FHA?” If the answer is anything above 500, move on. Lenders known for writing FHA loans down to 500 include Carrington Mortgage Services and a rotating cast of wholesale lenders that reach borrowers through independent brokers. If your broker submits through a wholesale channel, it helps to understand what that lender expects before the file goes in, including their documentation standards and how they treat alternative credit.
One example worth knowing: LoanStream Mortgage is a wholesale lender that shows up on a lot of low-score FHA and non-QM approvals, and their process differs meaningfully from a retail bank’s.
What a 520 actually costs you in dollars
Say you’re buying a $250,000 house with 10% down. That’s a $25,000 down payment and a $225,000 base loan. FHA’s 1.75% upfront mortgage insurance premium adds $3,937, which most borrowers finance, bringing the loan to about $228,900.
At a 520 score, expect a rate somewhere in the high 7s to mid 8s. Call it 8%. Principal and interest lands around $1,680 a month. Annual mortgage insurance at 0.50% adds roughly $95. Taxes and homeowners insurance on a $250,000 home might run $300 to $400 combined depending on where you live.
Now compare a borrower at 700 who puts 3.5% down and gets 6.75%. Their principal and interest on $225,000 is about $1,459. The gap is roughly $220 a month, plus the extra $16,250 in down payment the 520 borrower had to bring. Over five years that difference is north of $29,000 when you count the cash at closing.
That’s the honest trade. A 520 doesn’t mean you can’t buy. It means you pay more for the same house and you need more cash upfront.
The compensating factors that push a 520 file through
Underwriters aren’t scoring robots. FHA’s automated system, TOTAL Scorecard, will refer a low-score file to manual underwriting, and a human then weighs the whole picture. These are the things that move a 520 from maybe to yes:
- Debt-to-income under 43%. Under 36% is better. If your housing payment plus all minimum debt payments eats 50% of gross income, no lender will overlook the score.
- Cash reserves. Three to six months of payments sitting in an account after closing signals you’re not one flat tire away from default.
- Stable employment. Two years in the same line of work, even across employers.
- Twelve months of on-time rent. FHA allows alternative credit references like rent, utilities, and insurance paid on time, verified with bank statements or a landlord letter.
- A co-borrower. Adding a spouse or relative with a 640 score won’t erase yours, but many lenders use the higher of the two middle scores for pricing and can approve on the stronger file.
- No recent collections or judgments. The score matters less than what’s in the last 12 to 24 months.
Subprime and non-QM lenders worth calling
Outside FHA, there’s a small universe of lenders that specialize in damaged credit. They hold loans on their own books rather than selling them to Fannie or Freddie, so they can set their own rules. Expect 20% to 30% down, a rate in the 9% to 12% range, and a prepayment penalty on some products.
These loans make sense in narrow situations: self-employed borrowers with write-offs that crush their taxable income, or people who need to buy now and refinance in 24 months. For most 520 borrowers, FHA is cheaper. If you want a sense of the wider landscape before you start calling, this breakdown of the best mortgage lenders for low credit scores covers how pricing shifts as scores climb from the low 500s into the 600s.
If your 520 follows a bankruptcy or foreclosure
Timing rules override credit scores here. FHA requires two years from a Chapter 7 discharge and three years from a foreclosure or deed-in-lieu. Chapter 13 borrowers can sometimes qualify after 12 months of on-time trustee payments with court approval. A 520 six months after discharge isn’t a lending problem, it’s a waiting problem, and no amount of shopping fixes it.
If that’s your situation, the waiting periods and documentation requirements are laid out in more detail in this guide to mortgage options after bankruptcy. Worth reading before you spend an hour on the phone.
Five moves that can add 30 to 60 points before you apply
Every 20 points you gain widens your lender pool and drops your rate. These take 30 to 90 days and cost almost nothing:
- Pull all three credit reports free at AnnualCreditReport.com and dispute anything wrong. A 2013 FTC study found roughly one in four reports contained an error serious enough to affect a lending decision.
- Pay revolving balances down below 30% of the limit, ideally under 10%. Utilization is the heaviest factor after payment history and it updates fast.
- Don’t close old cards. Length of credit history matters, and closing an account cuts your total available credit, which pushes utilization up.
- Ask about a rapid rescore. A lender can submit proof of a paid-down balance and get scores refreshed in three to five business days, sometimes gaining 40 points in a week.
- Bring any collection under $100 current or paid. Small medical collections are commonly ignored by newer scoring models but still drag older ones down.
Questions to ask before you hand over an application
A 15-minute call with a loan officer will tell you whether you’re wasting your time. Ask these directly and listen for specific answers, not reassurances.
What’s your minimum FICO for FHA, and do you have any overlay above 500? Do you do manual underwriting when TOTAL Scorecard refers the file? How much does my score band cost me in rate compared to a 640 borrower, quoted in actual percentage points? Will you run my file through underwriting before I pay for the appraisal? And can you put the loan estimate in writing the same day I apply?
If a loan officer answers those with vagueness or starts pushing you toward a hard money loan at 14%, hang up. There are lenders who write 520 FHA files every week at rates within a point and a half of what a 700-score borrower gets. Finding them takes phone calls, a broker with wholesale access, and a clean file with low debt and documented rent history. None of that requires a perfect score.
