Short answer: yes, more often than people think. Longer answer: it depends on which loan you already have, how much equity you’ve built, and what you’re trying to accomplish. But the idea that a sub-600 score automatically locks you out of refinancing is a myth that keeps a lot of homeowners overpaying for no reason.
Let’s clear it up honestly, including the parts that aren’t great news, because you deserve the real version.
First, Why Your Score Dropped Probably Matters Less Than You Think
People assume lenders see a low number and stop reading. They don’t. An underwriter looking at a 580 wants to know the story behind it. A score that tanked two years ago after a medical event but has been climbing steadily since reads very differently from one that’s low because of three missed payments last month.
Recent active delinquency is the real obstacle, not the number by itself. If your credit took a hit during a rough patch and you’ve been current ever since, you’re in a stronger position than the headline figure suggests. So before you talk yourself out of it, look at the trend, not just the score.
The Loan You Have Right Now Changes Everything
Here’s the part most articles skip. Your refinance options depend heavily on your existing mortgage.
- If you have an FHA loan, you may qualify for an FHA Streamline Refinance. This is the most credit-friendly path out there because it often skips a new full credit check and a new appraisal entirely. The logic is simple: you’re already in an FHA loan and making payments, so the government-backed program just lowers your rate without re-underwriting your whole life. For a sub-600 borrower, this is frequently the single best option, and a lot of people who qualify don’t even know it exists.
- If you have a VA loan, the equivalent is the VA IRRRL (Interest Rate Reduction Refinance Loan), and it’s similarly forgiving on credit.
- If you have a conventional loan, it’s tougher. Conventional refinances are credit-score-driven, and under 600 you’ll face higher rates or outright denials. But you’re not stuck. Sometimes the smart move is refinancing out of a conventional loan into an FHA one, even temporarily, to escape a bad rate while you rebuild.
This is exactly why a one-size-fits-all answer fails. If you want to see how the paths compare for lower scores, this guide to refinancing with bad credit lays the options out side by side instead of pretending there’s one magic route.
Equity Is Your Secret Weapon
Credit score gets all the attention, but equity quietly does a lot of the heavy lifting.
If you owe $180,000 on a home worth $300,000, you’ve got $120,000 of equity, and that cushion makes a lender far more comfortable even with a shaky score. Why? Because if everything went sideways, the loan is still well-protected by the value of the house. Low risk to them means more flexibility for you.
The flip side is that if you’re barely above water, a low score hurts more, because there’s no equity buffer to offset it. So when you’re weighing your odds, don’t just check your credit. Check how much of the house you actually own.
What It’ll Cost You (The Honest Part)
Refinancing with a low score usually means a higher interest rate than someone with pristine credit would get. There’s no way around that. Risk gets priced in.
So run the actual math before you commit. A refinance only makes sense if the new payment saves you enough to clear the closing costs within a reasonable window, usually two to three years. If you’re paying $4,000 in costs to save $80 a month, you won’t break even for over four years, and that’s only worth it if you’re certain you’re staying put.
But here’s where it often does make sense. If your current rate is genuinely bad, the kind you got when your credit was at its worst, even a sub-600 refinance can drop your payment meaningfully. You don’t need a perfect rate. You need a better one than the one you’re trapped in.
The Move Almost Nobody Makes: Rebuild a Little First
Here’s a strategy that pays off more than people expect. If you’re close to a credit threshold, say you’re at 585 and the next pricing tier kicks in at 600 or 620, a few months of focused cleanup before you apply can change your rate enough to matter for the life of the loan.
The fastest levers:
- Pay down credit card balances. Your utilization ratio, meaning how much of your available credit you’re using, is one of the biggest and fastest-moving factors. Getting balances under 30% of your limits, and ideally under 10%, can lift your score in a single billing cycle.
- Don’t open anything new. Every hard inquiry and new account dings you temporarily. Go quiet for 60 to 90 days before you apply.
- Catch up and stay current. One more on-time month is one more data point in your favor.
Even a modest bump can move you into a better pricing tier. And worth knowing: when you do shop, multiple mortgage inquiries inside a roughly 45-day window count as a single inquiry, so getting quotes from several lenders won’t wreck the score you just worked to raise.
Where To Start
If you’re under 600 and tired of a payment that doesn’t reflect today’s rates, here’s the same sequence.
- Find out what loan you currently have. FHA or VA? Your easiest path may be a streamline. Conventional? You’ve got more analysis to do.
- Estimate your equity. The more you own, the more flexibility you’ve got.
- Spend 60 to 90 days on quick credit wins if you’re near a scoring threshold.
- Get quotes from lenders who actually work with lower scores. Not every lender does, and the ones who don’t will just waste your time. Sistar Mortgage, for instance, offers FHA streamline and cash-out options built for borrowers still rebuilding, the kind of flexibility a big-box bank’s credit overlay won’t allow.
- Run the break-even math before you sign anything.
A low credit score feels like a locked door. Usually it’s just a heavier one. Push on the right spot, meaning the right loan type, a little equity, and a few months of cleanup, and it opens more often than the internet would have you believe.
