Credit Score Requirements for Refinancing in 2026

Your credit score determines two things when you refinance: whether you get approved, and what interest rate you pay.

A 40-point difference in credit score can cost you $100/month on a $350,000 loan.

In my 15 years as a California mortgage broker, I've seen people get denied with a 615 score when they were one month away from hitting 620. I've also seen borrowers improve their score 60 points in 90 days and save $150/month.

Your credit score is the single biggest factor in your refinance rate—bigger than loan size, bigger than LTV, bigger than anything except the Federal Reserve.

Here's exactly what score you need, how your score affects your rate, and how to boost your score fast.

Minimum Credit Score by Loan Type

Different loan programs have different credit requirements:

Conventional Refinance: 620 Minimum

Standard requirement: 620 FICO score

Ideal score: 680+ (significantly better rates)

Best rates: 740+

Some lenders will go down to 600-620 if you have compensating factors (low LTV, low DTI, lots of cash reserves). But these are portfolio lenders charging higher rates.

Broker's Tip: If your score is 615-619, wait one month. Pay down your credit cards, dispute any errors, and reapply when you hit 620. The difference between "denied" and "approved" is often 5 points.

FHA Refinance: 580 Minimum

Standard requirement: 580 FICO score

Better approval odds: 620+

Ideal score: 640+

FHA is more lenient than conventional, but you'll pay mortgage insurance (MIP) for the life of the loan—which adds $200-$400/month to your payment.

If your score is 620+, go conventional. You'll get better rates and no permanent mortgage insurance.

VA Refinance: No Minimum (but lenders set their own)

VA guidelines: No minimum credit score required

Lender overlays: Most require 620+

Ideal score: 640+

The VA doesn't set a minimum score, but individual lenders do. Most VA lenders want at least 620. Some will go to 580-600 for veterans with strong compensating factors.

VA IRRRL streamline refinances are more lenient because they don't require income verification or appraisal. If you're struggling to qualify for a standard VA refinance, try the IRRRL.

USDA Refinance: 640 Minimum

Standard requirement: 640 FICO score

USDA loans are for rural properties. If you currently have a USDA loan, you can do a USDA Streamline refinance with more lenient credit requirements (sometimes down to 600).

How Credit Score Affects Your Interest Rate (2026 Rate Tiers)

Here's what you'll actually pay based on your credit score as of March 2026:

30-year fixed refinance rates:

| Credit Score | Rate | Monthly Payment (on $350k) | Total Interest (30 years) | |--------------|------|---------------------------|---------------------------| | 760+ | 6.34% | $2,183 | $435,800 | | 740-759 | 6.50% | $2,212 | $446,320 | | 700-739 | 6.60% | $2,241 | $456,760 | | 680-699 | 6.875% | $2,302 | $478,720 | | 660-679 | 7.125% | $2,364 | $500,040 | | 640-659 | 7.50% | $2,447 | $530,920 | | 620-639 | 7.875% | $2,533 | $562,880 |

Look at the difference between 760 and 640:

• Rate difference: 1.16%
• Monthly difference: $264/month
• Lifetime difference: $95,120 in extra interest

This is why I tell clients: if your score is 720, spend 2 months getting it to 740. You'll save $3,600/year.

Broker's Tip: Lenders use your middle score from all three bureaus. If your scores are 720 (Experian), 695 (TransUnion), and 710 (Equifax), they use 710. If two scores are the same, they use that score.

What Credit Score Do You Actually Have?

Most people don't know their real FICO score. Here's how to find it:

Free Ways to Check

1. AnnualCreditReport.com (official government site)

• Free credit report from each bureau once per year
• Shows your credit history but NOT your score
• Still worth checking for errors

2. Your Credit Card Company

• Most major issuers (Chase, Amex, Discover, Capital One) offer free FICO scores in their app
• This is your real FICO score (usually FICO 8)
• Updates monthly

3. Credit Karma

• Free, updates weekly
• Shows VantageScore (not FICO)
• VantageScore is usually 10-30 points different from FICO
• Good for tracking trends, not exact score

4. MyFICO.com

• $20-$40 for a one-time pull of all three bureaus
• This is the exact score lenders use (FICO 2, 4, 5 for mortgages)
• Worth it before applying for a refinance

Broker's Tip: Don't rely on Credit Karma's score when deciding whether to apply. It's often 20 points higher than your mortgage FICO score. Use your credit card's FICO score or pay for a MyFICO report.

What Lenders Actually Use

Mortgage lenders pull FICO scores from all three credit bureaus:

• Experian: FICO 2
• TransUnion: FICO 4
• Equifax: FICO 5

These are older FICO models. Your auto loan FICO or credit card FICO might be different.

They take the middle score. If your three scores are 680, 695, and 710, they use 695.

What Affects Your Credit Score (and How to Fix It)

Your FICO score is based on five factors:

1. Payment History (35% of Your Score)

What it is: Have you paid your bills on time?

Impact: One 30-day late payment can drop your score 60-100 points.

How to improve it:

• Set up autopay on all credit cards and loans
• If you missed a payment recently, call the creditor and ask them to remove it (sometimes they will if it's your first miss)
• Negative marks fade over time (7 years for most, 10 years for bankruptcy)

Broker's Tip: If you have a recent late payment, write a letter of explanation for your lender. Sometimes underwriters will overlook a single 30-day late if you have a valid reason (medical emergency, job loss, etc.).

2. Credit Utilization (30% of Your Score)

What it is: How much of your available credit are you using?

Formula: Total balances ÷ Total credit limits

Ideal utilization: Under 30% (under 10% is even better)

Example:

• Credit card 1: $2,000 balance / $10,000 limit
• Credit card 2: $500 balance / $5,000 limit
• Total: $2,500 / $15,000 = 16.7% utilization ✅ Good

If you're at 50%+ utilization, your score is getting hammered.

How to improve it fast:

• Pay down balances below 30% of each card's limit
• Ask for credit limit increases (this lowers utilization instantly without paying anything off)
• Pay off cards mid-cycle so the low balance reports to the bureaus

Broker's Tip: This is the fastest way to boost your score. Pay down $5,000 in credit card debt and your score can jump 40-60 points in 30 days.

3. Length of Credit History (15% of Your Score)

What it is: How long you've had credit accounts open

Impact: Longer history = better score

Average account age matters. If you have:

• Card 1: 15 years old
• Card 2: 8 years old
• Card 3: 2 years old

Your average age is 8.3 years.

How to improve it:

• Keep old credit cards open even if you don't use them
• Don't close your oldest accounts
• Become an authorized user on someone else's old account (their history adds to yours)

What NOT to do: Close old credit cards before refinancing. It tanks your average account age.

4. Credit Mix (10% of Your Score)

What it is: Do you have a variety of credit types (credit cards, car loans, mortgage, student loans)?

Impact: Having both revolving credit (credit cards) and installment loans (auto, mortgage) is better than only having one type.

How to improve it: Don't stress this. It's only 10%. Don't take out a car loan just to improve your credit mix.

5. New Credit / Hard Inquiries (10% of Your Score)

What it is: How many new accounts have you opened? How many hard credit pulls have you had?

Impact: Opening 3 new credit cards in a month tanks your score. A single hard inquiry drops it 5-10 points.

Mortgage shopping exception: Multiple mortgage inquiries within a 45-day window count as a single inquiry. Shop as many lenders as you want in that timeframe.

How to improve it:

• Stop applying for new credit 3-6 months before refinancing
• Don't open store credit cards
• Don't finance a car right before refinancing

Quick Wins: Boost Your Credit Score in 30-90 Days

If your score is 660 and you need 680, here's the playbook:

Week 1: Pull Your Credit Reports and Dispute Errors

Get your reports: AnnualCreditReport.com

Look for:

• Accounts that aren't yours
• Late payments you didn't actually make
• Incorrect balances
• Accounts marked "open" that you closed

Dispute errors: File disputes online with each bureau. They have 30 days to investigate.

Common errors:

• Collections that were paid but still showing as unpaid
• Duplicate accounts
• Late payments from 7+ years ago that should have fallen off

Potential score boost: 10-40 points

Week 2-3: Pay Down Credit Card Balances

Goal: Get under 30% utilization on each card (under 10% is ideal)

Strategy:

• Focus on cards with high utilization first
• If you have $5,000 to pay off, spread it across all cards proportionally to get each under 30%

Potential score boost: 40-80 points (this is the biggest lever)

Week 3-4: Ask for Credit Limit Increases

How: Call or log into each credit card account and request a limit increase.

Why it works: Increases your total available credit → lowers utilization → boosts score

Example:

• Before: $5,000 balance / $10,000 limit = 50% utilization
• After limit increase: $5,000 balance / $15,000 limit = 33% utilization

Potential score boost: 10-30 points

Warning: Some issuers do a hard pull for limit increases (which temporarily dings your score). Ask first: "Will this be a hard or soft inquiry?"

Month 2: Pay Bills on Time, Don't Open New Accounts

Do:

• Set up autopay on everything
• Keep balances low
• Wait patiently

Don't:

• Open new credit cards
• Finance a car
• Apply for personal loans
• Make any big financial moves

Score improvement timeline: Most changes show up on your credit report within 30 days (next billing cycle).

Month 3: Become an Authorized User (If Needed)

How it works: Ask a family member with excellent credit and a long credit history to add you as an authorized user on their oldest credit card.

Their account (and its perfect payment history) will show up on your credit report. Instant boost.

Potential score boost: 20-50 points

Warning: If they miss a payment or max out the card, it hurts your score too. Only do this with someone financially responsible.

Special Situations

You Have a Recent Bankruptcy

Chapter 7: You can refinance 4 years after discharge (2 years with FHA/VA and extenuating circumstances)

Chapter 13: You can refinance 2 years after discharge with on-time payments (1 year with FHA/VA and extenuating circumstances)

What to do: Focus on rebuilding credit during the waiting period. Get a secured credit card, pay everything on time, keep balances low.

You Have a Recent Foreclosure

Conventional: 7 years waiting period

FHA/VA: 3 years with extenuating circumstances

What to do: Similar to bankruptcy—rebuild credit, document any extenuating circumstances (job loss, medical emergency, divorce).

You Have Collections or Charge-Offs

Under $2,000 total: Most lenders ignore them

Over $2,000: You might need to pay them off or set up a payment plan before closing

Medical collections under $500: Ignored by most lenders

Broker's Tip: Don't pay off old collections right before applying. It can actually lower your score temporarily (the account gets updated as "recently active"). Pay them during the loan process if the lender requires it.

You're Self-Employed

Credit score requirements are the same, but lenders scrutinize your income more heavily.

You'll need:

• 2 years of tax returns
• Profit & loss statement
• Strong credit score (680+) to offset income volatility

Common Credit Mistakes That Tank Your Refinance

Mistake #1: Opening a new credit card during the refinance process. Even if you're approved, the lender re-pulls your credit right before closing. New credit = denied at the last minute.

Mistake #2: Paying off all your credit cards and closing them. Closing accounts lowers your available credit → raises utilization → drops score. Pay them down, keep them open.

Mistake #3: Ignoring small errors on your credit report. A single incorrect late payment can cost you 0.25%-0.50% on your rate. That's $50-$100/month.

Mistake #4: Assuming Credit Karma is accurate. It's often 20-30 points higher than your mortgage FICO. Use your credit card's FICO score or buy a MyFICO report.

Mistake #5: Co-signing a loan for a family member right before refinancing. Co-signed debt counts against your DTI. If it pushes you over 50% DTI, you're denied.

What to Do If Your Score Is Too Low

Option 1: Wait and improve it. If you're at 610 and need 620, spend 60-90 days paying down debt and disputing errors.

Option 2: Add a co-borrower. If your spouse or partner has better credit, add them to the application. Lenders use the lowest middle score of all borrowers, but a second income can offset a lower score.

Option 3: Try FHA. FHA allows scores as low as 580. You'll pay mortgage insurance, but you can refinance later to conventional once your score improves.

Option 4: Use a non-QM lender. These are portfolio lenders that don't follow Fannie/Freddie rules. They'll approve scores as low as 500-550, but you'll pay 8%-10% interest. Only use this as a last resort.

Broker's Tip: I've never recommended Option 4 to a client. The rates are predatory. It's better to spend 6 months fixing your credit and getting a conventional loan at 6.5%.

Ready to Refinance?

If your credit score is 620+, you're good to go. If it's 680+, you'll get competitive rates. If it's 740+, you'll get the absolute best rates available.

Step 1: Check your credit score using your credit card's app or MyFICO.com.

Step 2: If your score is under 680, spend 30-60 days paying down credit cards and disputing errors.

Step 3: Shop at least 3 lenders to compare rates based on your actual credit score.

Step 4: Lock your rate and proceed with the refinance.
