Ask five lenders what the minimum credit score to refinance a mortgage is and you’ll get five answers. That’s not because they’re hiding something. Refinance minimums come from two places: the loan program itself (Fannie Mae, Freddie Mac, FHA, VA, USDA) and the lender’s own rules layered on top. The second set is where most of the variation lives.
Here’s the practical version: most people who get turned down for a refinance aren’t blocked by a program rule. They’re blocked by a lender overlay, a loan-to-value problem, or a debt-to-income ratio that’s too tight. Knowing the actual floor for your loan type tells you whether to fix your credit first or start shopping today.
What Lenders Require, By Loan Program
These are the working minimums for a rate-and-term refinance on an owner-occupied home. Investment properties and cash-out deals sit higher, and I’ll get to those.
- Conventional (Fannie Mae/Freddie Mac): 620. Fannie’s automated system won’t approve a loan below that, and neither will Freddie’s. No exceptions through normal channels.
- FHA: 580 for a standard 97.5% LTV refinance. Down to 500 if you’re at or below 90% LTV. Below 500, the program doesn’t exist for you.
- VA: No official minimum. The VA doesn’t set a score floor, but nearly every VA lender imposes 580 to 620 to manage its own risk.
- USDA: 640 is the usual cutoff, though the agency’s automated system will sometimes approve 620 with strong compensating factors.
- Jumbo: 700 to 780, depending on the lender. Some portfolio lenders go lower for large balances with heavy reserves.
Two niche products skip the credit question almost entirely. An FHA Streamline needs a clean payment history (no 30-day lates in the past 12 months) and often no score at all. A VA IRRRL works the same way. If you already have an FHA or VA loan, check those programs before you spend a single month repairing credit.
The Gap Between “Approved” and “Affordable”
A 622 score gets you a conventional refinance in the same sense that a $20 bill gets you lunch. It happens, but you won’t love the price.
Mortgage pricing runs in 20-point credit buckets, and the worst bucket is expensive. On a $340,000 30-year fixed loan, the rate spread between a 640 score and a 760 score can run roughly 0.75 to 1.00 percentage points once loan-level price adjustments are baked in. That’s the difference between a $2,320 payment and a $2,121 payment — about $200 a month, or $72,000 over the life of the loan.
So the honest answer to “what’s the minimum score to refinance” is: the minimum to get approved is 620. The minimum to get a refinance that actually pays off is closer to 680. Everything between those numbers is a negotiation with your own math.
Conventional Refinance: 620 Is the Floor, Not the Target
Between 620 and 679, conventional refinancing is possible but picky. Lenders want to see compensating factors: six months of reserves, a debt-to-income ratio under 45%, a long clean payment history, or substantial equity. If you’re sitting in that band and wondering what’s realistic, what a 620–679 score really gets you on a conventional refinance breaks down the pricing tiers and which lenders are actually flexible.
Above 700, the overlays mostly disappear. Above 740, you’ve hit the top pricing bucket and additional points don’t buy you anything on rate.
Cash-Out Refinancing Pushes the Bar Higher
Pulling equity out is a riskier proposition for the lender, and the requirements reflect it. Conventional cash-out typically wants 620 as a hard floor but prices harshly below 680, and Fannie Mae caps cash-out at 80% LTV on a primary residence — which means your score and your equity both have to cooperate.
FHA cash-out requires 580 and 85% LTV. VA cash-out goes to 100% LTV with a 620-ish lender cutoff. If you’re weighing whether it’s worth applying with a thin file, this look at cash-out refinancing with bad credit covers what underwriters will and won’t overlook.
When Your Score Just Took a Hit
A recent collection, a maxed-out card, or a late payment that landed last month all look worse in underwriting than the same event two years ago. Timing matters as much as the number. If your score fell in the past 90 days, the playbook for refinancing after a recent score drop is worth reading before you assume you have to wait a year.
One point that surprises people: a single mortgage late payment reported in the last 12 months can sink an FHA Streamline or VA IRRRL that would otherwise need no credit score at all. Payment history is the gate on those products, not the score.
The Moves That Move Your Score Fastest
Most score damage is fixable in 30 to 60 days if you attack the right variables. The ones that matter for mortgage underwriting:
- Get every revolving balance under 30% of its limit. Utilization is the heaviest-weighted factor you control, and it recalculates as soon as the issuer reports.
- Pay cards down before the statement date, not the due date. The balance reported to the bureaus is the statement balance.
- Don’t close accounts or open new ones mid-application. Both drop your score, and new credit during underwriting can kill the file outright.
- Ask for a rapid rescore. Once you’ve paid down a balance, your loan officer can have it reflected in three to five business days instead of waiting for the natural cycle.
- Leave old disputes alone. An open dispute on a tradeline can force manual underwriting and stall everything.
There’s a longer version of this in how to improve your credit before refinancing without blowing three months on moves that don’t affect mortgage scoring.
Charge-Offs, Settlements and Other Messy Details
The score is a summary; underwriters read the file. A charge-off from 2019 with a zero balance is a very different thing from one still reporting a balance this month. Most lenders won’t approve a refinance while a charged-off account is unresolved, and paying it off doesn’t automatically remove it from your report.
If you settled a debt, expect a waiting period — conventional loans generally want four years from the settlement date, FHA wants three. Details vary enough that it’s worth checking exactly what lenders want to see after a debt settlement and how long you’ll wait. Settled debts do eventually stop being the deciding factor, but rarely on your preferred timeline.
Do the Math Before You Wait Six Months
Waiting to improve your score has a cost, and it’s usually larger than people estimate. Say your current mortgage rate is 7.875% on a $340,000 balance, and at a 640 score a refinance gets you 7.25%. That’s $155 a month saved. If six months of credit work could get you to 6.50% and $219 a month saved, waiting costs you roughly 6 × $155 in forgone savings — about $930 — plus whatever the market does to rates in the meantime.
Run both scenarios. If the gap between today’s offer and a realistic post-repair offer is small, refinance now and recapture later. If it’s 0.75 points or more, spend eight weeks on utilization and get a rapid rescore before you lock. Also ask each lender for a Loan Estimate on the same day with the same loan amount, because two lenders quoting the same rate can differ by $3,000 in fees, which changes your break-even month entirely.
The number that matters isn’t 620. It’s how many months of payments it takes to recover your closing costs, and whether waiting improves that figure enough to justify the delay.
