A 620 credit score sits in an awkward spot. It’s good enough that the door is open, and bad enough that everything costs more once you walk through it. Fannie Mae and Freddie Mac both set 620 as the absolute floor for a conventional loan, so you’re not locked out of the mainstream market. You’re standing on the threshold while the pricing engine treats you as the riskiest borrower it’s permitted to approve.
That’s not a reason to sign another 12-month lease. It’s a reason to go in knowing exactly which programs will take you, what the extra cost looks like in dollars, and which lenders don’t stack their own rules on top of the federal ones.
Which Loans Will Actually Take a 620
The program you choose drives your rate, your down payment, and how long you’ll carry mortgage insurance. Here’s the honest landscape.
- Conventional (Fannie/Freddie): 620 is the hard minimum. First-time buyers can put down 3%, repeat buyers typically 5%. Loan-level price adjustments will add roughly 0.5 to 0.75 percentage points to your rate compared with a 760 borrower.
- FHA: The 3.5% down version requires a 580. At 620 you’re comfortably inside the program, and FHA underwriters are noticeably more relaxed about debt ratios, recent collections, and thin credit files.
- VA: The VA itself publishes no score minimum, but most participating lenders apply an overlay at 620. A smaller group goes down to 580.
- USDA: Usually 640, though some lenders flex to 620 in eligible rural areas with compensating factors like reserves or a long employment history.
If this is your first purchase, the menu narrows a bit more than most people expect, and it’s worth reading up on the loans that still say yes to a first-time buyer with bad credit before you call anyone.
FHA Is Usually the Better Deal at 620
Conventional at 620 works, but the mortgage insurance math gets ugly. On a 3% down conventional loan at this score, private mortgage insurance often runs close to 1% of the loan balance per year. It stays until you reach 20% equity, which on a 30-year schedule can take seven or eight years without aggressive extra payments.
FHA charges 0.55% annually plus a 1.75% upfront premium that gets rolled into the loan. The catch: FHA insurance is permanent unless you refinance out of it, so the comparison usually comes down to which loan is cheaper over the next three to five years, not over thirty.
The Real Cost of a 620 Mortgage
Take a $320,000 house. A 620 borrower going conventional with 3% down finances about $310,400. At a 7.25% rate, principal and interest lands near $2,120 a month. Private mortgage insurance adds another $200 to $270 depending on the lender. Call it $2,350 all in before taxes and insurance.
A borrower with a 760 score on the same house might get 6.5% and pay around $1,960 in principal and interest. The monthly gap is roughly $150. Over 30 years, the higher rate alone costs somewhere near $55,000 in extra interest. That’s the price of the score, and it’s why paying down a credit card before you apply is often worth more than any negotiation at the closing table.
Your Debt-to-Income Ratio Can Sink the Whole Thing
A 620 score with a 40% debt-to-income ratio is a solid file. A 620 with a 52% ratio is a denial waiting to happen, because most conventional lenders cap DTI at 45% and only stretch to 50% when there are real compensating factors such as six months of reserves or a long, stable income history.
FHA is more forgiving, often approving to 50% and occasionally higher through automated underwriting. Before you shop, add up every minimum payment on your credit report and divide by gross monthly income. If you’re above 45%, paying off a car loan or a small balance can do more for your approval odds than another 20 points on your score.
Shop Five Lenders, Not One
Lender overlays are the wild card. A 620 that sails through one underwriter gets declined by another that requires 640 for the same FHA loan. Credit unions, community banks, and mortgage brokers all price risk differently, and the spread on a single day can be half a percentage point.
Start with institutions that openly work this segment of the market. A rundown of mortgage lenders for bad credit and what each one actually costs will save you a week of cold calls. Get quotes from at least five within a two-week window so the credit pulls count as a single inquiry for scoring purposes.
Three Fixes That Can Move Your Score in 60 Days
Get revolving balances under 10%
Credit utilization is the fastest-moving lever you have. A $5,000 card sitting at $4,500 (90% utilization) dropping to $400 can add 30 to 40 points within one billing cycle. If you have several cards, spread the balances rather than maxing one and zeroing another.
Leave your old accounts alone
Closing a card you’ve held for nine years shortens your average account age and cuts available credit at the same time. Pay it down, keep it open, and use it for one small recurring charge. And absolutely do not co-sign a loan for anyone while you’re applying.
Ask about a rapid rescore
If you pay off a collection or a maxed card, a lender can request a rapid rescore through the credit bureaus and have your file updated in three to five business days instead of the usual 30 to 45. It usually costs $25 to $50 per item per bureau, and it’s the single most useful tool available when you’re days from a rate lock.
Buy Now or Wait for a Better Score?
Waiting only makes sense if you have a concrete plan and a timeline. If you can realistically get to 660 in four months by clearing two cards, the rate improvement is real and permanent. If your score is stuck because of a recent short sale or a string of late payments, waiting a year might gain you 15 points and cost you more in rent and price appreciation than you save.
It also helps to know exactly where the next tier sits. The approval picture shifts noticeably at buying a house with a 600 credit score, where conventional lending largely disappears and FHA becomes the main road. Below that, at a 580 credit score, the trade-offs get sharper still. Knowing the boundaries tells you whether 40 points is worth chasing.
Your Next 90 Days
Pull your three-bureau report from AnnualCreditReport.com and dispute anything that’s plainly wrong: a paid collection still showing a balance, a duplicate medical bill, an account that isn’t yours. Roughly one in five reports contains an error serious enough to affect a score.
Then gather the paperwork underwriters will ask for twice: two recent pay stubs, two months of bank statements on every account you’ll use for the down payment, the last two years of W-2s or tax returns if you’re self-employed, and a gift letter if family is helping. Unexplained deposits get flagged, so keep a paper trail for anything unusual.
Finally, ask every lender you speak with about down payment assistance. State housing finance agencies, city programs, and some credit unions offer grants or deferred second mortgages worth 3% to 5% of the purchase price, and many are reserved for buyers below a certain income or credit threshold. On a $320,000 house, a 3% grant is $9,600 you don’t have to save. Stack that with a 620 approval and a realistic budget, and the purchase stops looking like a stretch.
