Should I wait to improve my credit score or refinance now?

Wait if you're just below a key threshold (579→580, 615→620, 655→660) and can reach it within 3–6 months by paying down credit cards. Refinance now if your current rate is 1%+ above today's market, you can't improve your score quickly, your loan is already FHA (Streamline available), or you're VA-eligible (IRRRL requires no minimum score at the VA level).

Can You Refinance With Bad Credit?

Q: Can I refinance after a foreclosure or bankruptcy?

Yes, after a waiting period. FHA: 3 years after foreclosure, 2 years after Chapter 7. VA: 2 years after both. Conventional: 7 years after foreclosure, 4 years after Chapter 7. USDA: 3 years after both. Waiting periods run from the discharge or completion date, not the filing date.

Q: Is cash-out refinancing harder with bad credit?

Yes. Cash-out refinances have stricter score requirements than rate-and-term refinances. FHA requires 580 for cash-out. Conventional cash-out typically requires 620+. VA cash-out has no VA minimum but most lenders require 620+. If you have a low score and need equity access, ask about a HELOC from your current servicer as an alternative.

The Short Answer: Yes, You Can — With the Right Program

A low credit score doesn't automatically disqualify you from refinancing. Federal loan programs — especially FHA — were designed to serve borrowers that conventional lenders won't. The key is knowing which programs your score qualifies for, what the rate penalty looks like, and whether the math still works in your favor after accounting for higher costs.

For most homeowners with scores between 500 and 660, the realistic path to refinancing runs through FHA, VA (if eligible), or USDA (if eligible) rather than conventional Fannie Mae/Freddie Mac loans. Here's a breakdown by credit score range.

Minimum Credit Score by Refinance Type

Credit Score	Conventional Refi	FHA Refi	VA IRRRL	Rate Impact vs. 740+
500–579	Not eligible	Eligible (90% max LTV)	Some lenders (varies)	+1.5%–2.5%
580–619	Not eligible (most lenders)	Eligible (97.75% max LTV)	Eligible (580+ most lenders)	+1.0%–1.75%
620–659	Eligible (with rate adjustment)	Eligible	Eligible	+0.5%–1.0%
660–699	Eligible (near-standard)	Eligible	Eligible	+0.25%–0.5%
700–739	Eligible (good rates)	Eligible	Eligible	+0.1%–0.2%

Note: Individual lender overlays (internal risk policies) often set minimums higher than program guidelines. Even if FHA accepts 580, many FHA-approved lenders require 620+. Shop multiple lenders if you're near the low end.

FHA Refinance: The Most Accessible Option

The Federal Housing Administration (FHA) refinance is the most widely available option for borrowers with damaged credit. The FHA sets minimum standards, then individual lenders can set stricter overlays — but starting guidelines are:

500–579 credit score: Eligible, but limited to 90% LTV (must have at least 10% equity)
580+ credit score: Eligible up to 97.75% LTV (just 2.25% equity required)
Mortgage insurance: Required — an upfront premium of 1.75% of the loan amount, plus an annual MIP of 0.55%–1.05%

The FHA Streamline Refinance is even more accessible — it doesn't require a new appraisal or income verification, just a net tangible benefit (lower rate or payment) and a history of on-time payments on your current FHA loan.

          Important: If your current loan is FHA, the Streamline path is your fastest route to a lower rate regardless of credit score. If your current loan is conventional, you'd be doing a full FHA refinance, which includes an appraisal and income verification.
        

VA and USDA Refinances With Low Credit

VA Loans (Veterans and Active-Duty Military)

The VA does not publish a minimum credit score for refinancing — it's left to individual lenders. In practice, most VA-approved lenders set their minimum at 580 or 620. The VA IRRRL (Interest Rate Reduction Refinance Loan) is particularly forgiving: it requires no appraisal, no income verification, and the VA funding fee (0.5% for IRRRL) can be rolled into the loan. This makes it the most accessible refinance option for eligible veterans regardless of credit score.

USDA Streamlined-Assist

If you have a USDA Rural Development loan, the Streamlined-Assist program allows refinancing without income verification or an appraisal, and there is no minimum credit score set by USDA guidelines (though lender overlays typically require 580–620). You must have made 12 consecutive on-time mortgage payments and demonstrate a minimum $50 payment reduction.

The Real Cost of a Low Credit Score

Refinancing with a lower credit score is possible — but it costs more. Every tier down from a 740+ score increases your interest rate through pricing adjustments called Loan-Level Price Adjustments (LLPAs) on conventional loans, and through higher MIP rates on FHA loans.

Here's a concrete example of what a 100-point score difference can mean on a $300,000 30-year refinance:

Score 760: Rate ~6.5% → Monthly payment $1,896 → Total interest $382,560
Score 660: Rate ~7.25% → Monthly payment $2,047 → Total interest $437,100
Score 580: Rate ~7.75% (FHA) → Monthly payment $2,148 + MIP → Total interest $473,000+

The 180-point gap between 580 and 760 costs approximately $250+ per month and over $90,000 in total interest over 30 years. This is why improving your score before refinancing — even by 40–60 points — can be worth waiting several months to achieve.

How to Improve Your Score Before You Refinance

If you're at 580–620 and want to reach 660+, here are the most impactful steps, roughly ordered by speed of effect:

Pay down credit card balances. Credit utilization (balance ÷ limit) below 30% is ideal; below 10% is best. Each card you pay down can add 10–30 points within 30 days.
Dispute errors on your credit report. Check all three bureaus (Equifax, Experian, TransUnion) at AnnualCreditReport.com. Inaccurate derogatory marks are common and can be removed, sometimes adding 20–50 points.
Make all payments on time for 6–12 months. Payment history is 35% of your FICO score. Lenders want to see a clean recent history even if there are older negatives.
Don't close old accounts or open new ones. Account age and new inquiries both affect your score. Keep existing accounts open.
Become an authorized user on a family member's card. If a family member has a long-standing, low-utilization card, being added as an authorized user can boost your score without you needing to use the card.

With focused effort, moving from 580 to 660 within 6–9 months is realistic for many borrowers. Check our refinance situations guide to understand when the timing is right to act.

How Mortgage Lenders Actually Read Your Credit Score

Most consumers monitor their score through Credit Karma, their bank, or a credit card portal — these typically show FICO 8 or VantageScore. Mortgage lenders use different versions: FICO 2 (Experian), FICO 4 (TransUnion), and FICO 5 (Equifax), obtained in a tri-merge credit pull.

The qualifying score is the middle of the three — not the highest, not an average. If your three scores are 590, 608, and 641, your mortgage qualifying score is 608. This distinction matters because:

Consumer scores (FICO 8) often run 10–40 points higher than mortgage scores for the same borrower
You may feel confident at 640 based on your app but qualify at 602 when the lender pulls
On joint applications, lenders use the lower of the two borrowers' middle scores — a co-borrower with a high score doesn't raise yours

Before applying, ask a lender or mortgage broker to pull a tri-merge report. This is the only way to know the exact number that will determine your program eligibility and rate tier.

Refinance Options by Credit Score Range — Detailed

Score 500–579: FHA Only, Strict Equity Requirement

At 500–579, the only federal program available is a standard FHA refinance, and it comes with significant restrictions. You must have at least 10% equity (LTV ≤ 90%), and your rate will be 1.5%–2.5% above what a 740+ borrower receives. Many FHA-approved lenders have overlay minimums of 580, so finding a willing lender requires extra shopping — regional banks and credit unions sometimes have more flexible overlays than national lenders.

FHA Streamline (if your current loan is already FHA) has no published VA minimum, but lender overlays typically still apply. The priority at this score range is reaching 580 as quickly as possible — it's a threshold that expands your LTV limit from 90% to 97.75% and opens more lenders.

Key threshold: Getting from 579 to 580 opens FHA refinancing at up to 97.75% LTV and dramatically increases the number of lenders willing to approve you. Even a single point matters.

Score 580–619: FHA and VA Are Your Best Paths

At 580–619, you have meaningful options. FHA becomes fully accessible at 97.75% LTV. VA IRRRL is available if you have an existing VA loan — the VA itself sets no minimum score, and many VA-approved lenders will go to 580. USDA Streamlined-Assist is available if you have an existing USDA loan (no appraisal, no income verification, minimum $50 payment reduction required).

Conventional refinancing remains essentially unavailable at most lenders in this range. If you're at 615–619 and can reach 620 within 3–6 months, consider waiting — crossing 620 opens the conventional door and lowers your rate by roughly 0.5%–1.0% through reduced LLPAs.

Score 620–659: Conventional Opens, But With Pricing Penalties

At 620, conventional (Fannie Mae/Freddie Mac) refinancing becomes available — but you'll pay for it. Loan-Level Price Adjustments (LLPAs) at 620 with 80% LTV add approximately 1.75–2.5 percentage points in fee, which translates to a rate roughly 0.4%–0.6% above a 740+ borrower. At higher LTVs, the penalty compounds.

In this range, run both a conventional and FHA quote. FHA MIP is ongoing, but LLPAs are a rate hit on every payment for the life of the loan. The right choice depends on your LTV, loan size, and how long you'll keep the loan. At 640+, shop 3–4 lenders — overlay minimums vary widely in this range, and one lender's 640 is another's 620.

Score 660–699: Near-Standard Rates, Full Program Access

At 660+, you're in competitive territory. LLPA adjustments shrink to 0.25%–0.5% and conventional rates are close to best available. If you have 20%+ equity, conventional at this score is often the best outcome — no MIP, competitive rate, and maximum lender choice. The 680 sub-threshold is another notable milestone on LLPA tables, so reaching it if you're at 661–679 is worth a short wait if achievable quickly.

Conventional Refinancing and LLPAs: What Changes at Each Score Tier

Loan-Level Price Adjustments (LLPAs) are fees charged by Fannie Mae and Freddie Mac based on your credit score and LTV. They're added to your rate — you don't pay them separately. The LLPA schedule is public and changes periodically. Key tier breakpoints as of 2026:

Credit Score	LTV 75–80%	LTV 80–90%	LTV 90–95%
620–639	~2.25 pts	~2.75 pts	~3.25 pts
640–659	~1.75 pts	~2.25 pts	~2.75 pts
660–679	~1.00 pt	~1.50 pts	~2.00 pts
680–699	~0.50 pts	~0.75 pts	~1.00 pt
700–719	~0.25 pts	~0.50 pts	~0.75 pts
720–739	0 pts	~0.25 pts	~0.50 pts
740+	0 pts	0 pts	~0.25 pts

Note: Points = percentage of loan amount, added at closing or baked into rate. Actual LLPA tables at Fannie Mae's website. Values are approximate.

FHA does not use LLPAs, but charges MIP (0.55%–1.05% annual) on top of your rate. For a borrower at 630 with 85% LTV, FHA MIP of 0.85%/year vs. a conventional LLPA hit of ~2.5 points: if you're keeping the loan less than 4 years, LLPA-based conventional could be cheaper (one-time hit vs. ongoing premium). Beyond 4 years, ongoing MIP usually costs less than the permanent rate increase from LLPAs.

Should You Wait to Improve Your Score, or Refinance Now?

This is the central decision for every borrower in the 580–660 range. Both sides have real costs — the rate penalty you pay now, and the months of higher payments you sacrifice while waiting.

Refinance Now if:

Your current rate is 1.5%+ above today's market — even with the credit penalty, you're likely saving money
Your current loan is FHA — FHA Streamline is available regardless of score with no appraisal or income verification
You're VA-eligible with an existing VA loan — VA IRRRL has no VA-mandated score minimum and VA rates are often competitive even with low scores
You cannot realistically improve your score within 6 months (derogatory marks, not credit card debt, are dragging your score)
You need the monthly cash flow relief now — waiting costs real money each month

Wait 3–6 Months if:

You're at 575–579 — paying down one credit card could get you to 580, which opens 97.75% LTV and more lenders
You're at 615–619 — reaching 620 opens conventional and saves 0.5%–1.0% in rate for the life of the loan
You're at 655–659 — reaching 660 reduces LLPAs significantly on conventional loans
You have high credit card balances you can pay down — utilization reduction is the fastest, most predictable score improvement method

The Math on Waiting

On a $300,000 loan at 7.75% (current bad-credit FHA rate), each month of waiting costs approximately $1,938/month in P&I. If reaching 620 saves 0.75% in rate ($150/month), and waiting 4 months costs $7,752 in payments at the old rate, you break even on the wait in 52 months. If you're planning to stay longer than 52 months, waiting 4 months pays off. Use the break-even calculator to run this math with your actual numbers.

Frequently Asked Questions

What is the minimum credit score to refinance a mortgage?

The minimum credit score depends on the loan type. Conventional refinances typically require 620. FHA refinances accept scores as low as 580 (or even 500 with 10%+ equity). VA refinances have no official minimum score, though most lenders require 580–620. The lower your score, the higher your interest rate will be.

Can I refinance with a 580 credit score?

Yes, through the FHA program. FHA allows refinancing with a 580 credit score at up to 97.75% LTV. Some FHA lenders will go down to 500 if you have at least 10% equity (90% LTV). Expect your interest rate to be 1–2 percentage points higher than a borrower with a 740+ score.

Does refinancing hurt your credit score?

Temporarily, yes. Applying for a refinance triggers a hard credit inquiry, which may reduce your score by 5–10 points for up to a year. However, if you rate-shop within a 45-day window, FICO counts all mortgage inquiries as a single event, minimizing the impact. Over time, a refinance to a lower rate can improve your score by reducing your debt-to-income ratio.

How can I improve my credit score before refinancing?

The fastest ways to raise your score are: paying down credit card balances (reduces utilization), disputing errors on your credit report, making all payments on time for 6–12 months, and avoiding new credit applications. Moving from 580 to 660 can lower your mortgage rate by 0.5–1%, saving hundreds per month.

Can I do an FHA Streamline refinance with bad credit?

Yes — if your current loan is already FHA. The FHA Streamline program has no official minimum credit score, though individual lenders typically set overlays at 580–620. It requires no appraisal, no income verification, and only a clean recent payment history: no 30-day lates in the last 3 months and no more than one in the last 12 months. This is the fastest and most accessible refinance path for borrowers with existing FHA loans, regardless of credit score.

Can I refinance after a foreclosure or bankruptcy?

Yes, after a waiting period from the discharge or completion date (not the filing date): FHA requires 3 years after foreclosure and 2 years after Chapter 7 bankruptcy. VA requires 2 years after both. Conventional requires 7 years after foreclosure and 4 years after Chapter 7. USDA requires 3 years after both. Extenuating circumstances (documented job loss, serious illness) can shorten FHA and VA waiting periods to 1 year in some cases.

Is cash-out refinancing harder with bad credit?

Yes. Cash-out refinances have stricter credit requirements than rate-and-term refinances. FHA requires 580 for cash-out (vs. 500 for rate-and-term). Conventional cash-out typically requires 620+ with larger LLPA surcharges. VA cash-out requires no VA minimum but most lenders set 620+. If you have a low score and need equity access, ask your current servicer about a HELOC as an alternative — some banks will approve HELOCs for existing customers at lower score thresholds than a new cash-out refi.

Does adding a co-borrower with good credit help?

Only for income, not the rate. On joint applications, lenders use the lower of the two borrowers' qualifying credit scores. A co-borrower with 780 credit doesn't improve your 590 qualifying score — you still get priced at 590. However, a co-borrower's income is fully counted in the debt-to-income ratio, which can help with the income side of qualification. If you're close to a key score threshold yourself, focusing on improving your own score is typically more impactful than adding a co-borrower.

What credit score do I need for a no-closing-cost refinance?

No-closing-cost refinances (where the lender absorbs costs in exchange for a higher rate) are available at any qualifying score. However, if your credit already carries a rate penalty of 1–2%, a no-closing-cost premium of another 0.25%–0.5% on top may produce an unworkably high rate. Run the math: compare your credit-adjusted rate + no-closing-cost premium against the rate-with-costs break-even using the break-even calculator. For most low-credit borrowers, paying costs upfront and recovering them through savings is a better deal.
