Your credit score is the single biggest factor in the refinance rate you’ll qualify for — and the difference between a 680 and a 760 can mean thousands of dollars over the life of your loan. Here’s what lenders actually require, what the score tiers mean for your rate, and how to improve your score before you apply.
Minimum Credit Score Requirements by Loan Type
Conventional refinance: Most lenders require a minimum score of 620, though some will go to 580 with compensating factors (low DTI, significant equity, strong income). Best rates start at 740+.
FHA refinance: Minimum 580 for most FHA refinances. For an FHA Streamline refinance (available to existing FHA loan holders), some lenders accept scores as low as 500-580 with certain conditions, and the streamline process may not require a new appraisal or credit check at all.
VA refinance (IRRRL): The VA doesn’t set a minimum credit score, but most lenders require 580-620. VA Interest Rate Reduction Refinance Loans have relaxed requirements for existing VA borrowers.
USDA refinance: Minimum 640 for most USDA streamline refinances. Available only for existing USDA loan holders in eligible rural areas.
Jumbo refinance: 700+ minimum for most lenders, with best pricing at 740+. Jumbo loans carry more lender risk, so credit requirements are stricter across the board.
How Your Score Affects Your Refinance Rate
Lenders use risk-based pricing — higher scores get lower rates. The impact is substantial. Based on current market conditions in March 2026, here’s an approximate rate spread across credit tiers on a $300,000 30-year conventional refinance:
760+: Best available rate (approximately 6.0-6.2%). This is the “excellent” tier where you qualify for the lowest pricing adjustments.
720-759: Add roughly 0.125-0.25% to the best rate. Still strong pricing with minimal adjustment.
680-719: Add roughly 0.25-0.5%. Decent terms, but you’re leaving money on the table compared to where you’d be at 740+.
640-679: Add roughly 0.5-1.0%. You’ll qualify, but the rate premium is noticeable. On $300,000, an extra 0.75% costs about $150/month — $54,000 over 30 years.
620-639: Add 1.0-1.5%+. Some lenders won’t quote at this level, and those who do charge significant rate premiums. Consider improving your score before applying.
The difference between a 660 score and a 760 score on a $300,000 loan can be $100-$200 per month. Over 30 years, that’s $36,000-$72,000 in extra interest. Spending 3-6 months improving your credit before refinancing can be the highest-ROI financial move you make.
How to Boost Your Score Before Refinancing
Pay down credit card balances (biggest impact, fastest results). Your credit utilization ratio — how much of your available credit you’re using — accounts for roughly 30% of your score. Dropping from 50% utilization to under 10% can boost your score 40-80 points in a single reporting cycle. Pay down cards aggressively in the 2-3 months before applying.
Don’t close old accounts. Length of credit history matters. That old credit card you never use is helping your score by extending your average account age and adding to your total available credit. Leave it open.
Dispute errors on your credit report. Check all three bureau reports (Equifax, Experian, TransUnion) at AnnualCreditReport.com. Incorrect late payments, accounts that aren’t yours, and wrong balances are common. Disputes can be filed online and typically resolve in 30-45 days.
Avoid new credit applications. Each hard inquiry can drop your score 5-10 points. In the 3-6 months before a refinance, don’t apply for new credit cards, auto loans, or personal loans. The exception is shopping for mortgage rates — multiple mortgage inquiries within a 14-day window count as a single pull.
Become an authorized user. If a family member has a credit card with a long, clean payment history and low utilization, being added as an authorized user can boost your score. The account’s positive history gets added to your credit file. You don’t even need to use the card.
Set up autopay on everything. Payment history is 35% of your score — the single largest factor. One late payment can drop your score 50-100 points and stays on your report for 7 years. Autopay eliminates the risk of forgetfulness.
What If Your Score Isn’t Where You Want It?
If your score is below 620 and you need to refinance, FHA loans have the most lenient requirements. If you’re an existing FHA borrower, an FHA Streamline refinance may not require a credit check at all.
If you have time, a focused 3-6 month credit improvement effort can move your score 50-100+ points. The combination of paying down cards, disputing errors, and avoiding new inquiries works faster than most people expect.
A licensed mortgage professional can pull your credit, show you exactly where you stand across all three bureaus, and tell you what score tier you’re in for current rates. Start the conversation here — there’s no obligation, and knowing your numbers is the first step whether you refinance now or in 6 months.
Frequently Asked Questions
Does checking my own credit score hurt it?
No. Checking your own credit is a “soft inquiry” and has zero impact on your score. You can check daily without any effect. Hard inquiries (from lender applications) do impact your score, but mortgage shopping within a 14-day window counts as a single inquiry.
How long does it take to improve a credit score?
Paying down credit cards can show results in 30-45 days (one reporting cycle). Disputing errors takes 30-45 days. Building payment history takes 6-12 months. For most homeowners, 2-3 months of focused effort can move the needle meaningfully — often enough to jump a pricing tier.
Can I refinance with a bankruptcy on my record?
Yes, after a waiting period. Chapter 7 bankruptcy requires a 2-4 year waiting period depending on loan type (2 years for FHA, 4 for conventional). Chapter 13 may allow refinancing after 12 months of on-time plan payments with court approval. Your score will need to meet minimum requirements at the time of application.
