You're considering refinancing your mortgage to lock in a lower rate. Smart move — except you've heard refinancing can tank your credit score.
So what's the truth?
Refinancing *will* temporarily lower your credit score, but we're usually talking 5-10 points, not 50. The hit is brief. The savings from a lower interest rate? Those last for years.
Here's exactly what happens to your credit when you refinance, why the temporary dip happens, and how to minimize the damage.
## Why Refinancing Affects Your Credit Score
Refinancing is essentially taking out a new loan to replace your old one. Anytime you apply for new credit, three things happen that impact your score:
### 1. Hard Inquiries Hit Your Report
When you shop for refinancing, every lender that pulls your credit report creates a hard inquiry. Each hard inquiry can drop your score by 2-5 points.
The good news: the credit scoring models treat multiple mortgage inquiries within a 14-45 day window as a single inquiry. Shop around within that window and you'll only get dinged once.
### 2. Your Average Account Age Drops
Your credit score factors in the average age of all your accounts. When you refinance, your old mortgage gets marked as "closed" and a new mortgage account opens with a brand new open date.
If your original mortgage was 10 years old and you refinance, you just lost a mature account and added a brand new one. This lowers your average account age, which can drop your score by a few points.
### 3. Your Credit Mix Changes Temporarily
Credit scoring models like to see a healthy mix of credit types — revolving credit (credit cards) and installment loans (mortgages, car loans). When you close one mortgage and open another, your credit mix temporarily shifts.
This factor is relatively minor — it only accounts for about 10% of your FICO score — but it contributes to the overall dip.
## How Much Does Refinancing Actually Lower Your Score?
Most people see a drop of **5-10 points** after refinancing. Some people see no drop at all. A few see 15-20 points if their credit profile is thin.
Here's what determines how much your score drops:
- **How many lenders you shop with** — one inquiry vs. ten makes a difference (though remember, multiple mortgage inquiries in a short window count as one)
- **How old your original mortgage was** — closing a 15-year-old mortgage hurts more than closing a 2-year-old one
- **How many other accounts you have** — if you only have three credit accounts total, losing one mature mortgage hits harder
- **Your current score** — people with scores above 760 tend to see smaller drops because they have strong credit profiles overall
## How Long Does the Credit Score Drop Last?
The drop is temporary. Most people recover within 3-6 months if they continue making on-time payments on the new mortgage.
Hard inquiries stay on your report for two years but only impact your score for the first 12 months. After a year, they stop affecting your score entirely.
Your new mortgage will age over time, which gradually improves your average account age. Within 6-12 months, your score typically bounces back to where it was — and sometimes higher if the refinance lowered your debt-to-income ratio.
## When Refinancing Can Actually *Help* Your Credit
Believe it or not, refinancing can sometimes improve your credit score in the long run. Here's how:
### Lower Monthly Payments = Better Payment History
If refinancing lowers your monthly payment, you're less likely to miss payments. Payment history is the single biggest factor in your credit score (35% of your FICO score), so consistent on-time payments after refinancing will boost your score over time.
### Cash-Out Refinancing to Pay Off High-Interest Debt
If you do a cash-out refinance and use the proceeds to pay off credit card balances, you'll dramatically lower your credit utilization ratio. Utilization accounts for 30% of your FICO score, so this can actually *increase* your score even though you just added a hard inquiry.
Example: You owe $15,000 across three credit cards with a combined limit of $20,000. That's 75% utilization — terrible for your score. You do a cash-out refi, pay off the cards, and now your utilization is 0%. Your score could jump 30-50 points within a few months, even after the 5-10 point dip from the refinance itself.
### Consolidating Debt Improves Your Debt-to-Income Ratio
Lenders look at your debt-to-income ratio (DTI) when evaluating you for future credit. If refinancing lowers your monthly debt payments, your DTI improves, making it easier to qualify for other loans down the road — even if your credit score temporarily dips.
## How to Minimize the Credit Score Hit When Refinancing
You can't avoid the credit impact entirely, but you can minimize it:
### Shop for Rates Within a 14-45 Day Window
Credit scoring models recognize that mortgage shoppers need to compare offers. As long as you submit all your applications within a short period (FICO uses a 45-day window, VantageScore uses 14 days), multiple hard inquiries will count as just one.
Don't drag out your rate shopping over three months. Compress it into two weeks.
### Don't Open New Credit Accounts Right Before Refinancing
If you're planning to refinance in the next 6 months, avoid opening new credit cards or taking out new loans. Every new account lowers your average account age, and lenders scrutinize your recent credit activity when approving a refinance.
### Keep Your Old Credit Cards Open After Refinancing
If you used a cash-out refi to pay off credit card debt, don't close those cards. Closing them will lower your total available credit, which can spike your utilization ratio and hurt your score.
Keep the cards open, use them occasionally for small purchases, and pay them off in full every month.
### Make Sure Your Credit Report is Clean Before Applying
Before you start shopping for refinancing rates, pull your credit reports from all three bureaus (Equifax, Experian, TransUnion) and check for errors. Dispute any inaccuracies before applying.
A few points can make the difference between getting approved at a great rate or getting denied. If you find errors you can't remove on your own, professional credit repair services can help you dispute them strategically.
## What Credit Score Do You Need to Refinance?
Most conventional lenders want to see a credit score of at least 620 for a standard refinance. For the best rates, you'll want a score of 740 or higher.
FHA refinances (also called FHA Streamline Refinances) are more forgiving. You can qualify with a score as low as 580, sometimes even lower if you have a strong payment history on your current FHA loan.
VA refinances (for veterans and active military) also have flexible credit requirements, though most lenders still prefer scores above 620.
If your score is below 620 and you're struggling to qualify, improving your credit before refinancing can save you thousands in interest. Even a 20-point boost can drop your rate by 0.25%-0.5%.
## Should You Refinance If Your Credit Score is Already Low?
If your score is in the 500s or low 600s, refinancing might not be your best move right now — not because of the temporary credit hit, but because you probably won't qualify for a great rate.
Here's a better strategy:
1. **Focus on credit repair first.** Remove inaccurate negative items, pay down high-balance credit cards, and catch up on any late payments.
2. **Wait 6-12 months** while your score climbs.
3. **Then refinance** when you can qualify for a meaningfully better rate.
The difference between a 6.5% rate and a 5.5% rate on a $300,000 mortgage is about $180/month — $2,160/year. Waiting a few months to improve your score can literally save you thousands.
## What If You Already Refinanced and Your Score Dropped?
Don't panic. The drop is temporary.
Focus on these things over the next 6 months:
- **Make every payment on time** — set up autopay if you haven't already
- **Keep your credit card balances low** — ideally under 10% of your limits
- **Don't apply for new credit** — let your credit profile stabilize
- **Monitor your credit reports** — make sure the refinance is being reported correctly
If your old mortgage isn't showing as "paid in full" or if the new mortgage has errors, dispute them immediately. Reporting errors can drag your score down longer than necessary.
## When Refinancing is Worth the Temporary Credit Hit
Refinancing makes sense when the long-term savings outweigh the short-term credit dip. Here's when it's worth it:
- **You can lower your interest rate by at least 0.75%** — the savings will far exceed the temporary score drop
- **You're switching from an adjustable-rate mortgage (ARM) to a fixed-rate mortgage** — locking in predictable payments is worth a few points
- **You're shortening your loan term** (e.g., from a 30-year to a 15-year mortgage) — you'll pay off your home faster and save massive interest
- **You're doing a cash-out refi to consolidate high-interest debt** — paying off 20% APR credit cards with a 6% mortgage is a no-brainer
If you're refinancing just to shave 0.25% off your rate and you'll break even in 5 years, it might not be worth it — especially if you're planning to move soon.
## What If You Need to Buy a House Right After Refinancing?
If you're planning to buy a second home or investment property within the next 6 months, think twice before refinancing. The temporary credit drop could hurt your ability to qualify for the new mortgage.
Wait until after you close on the new property, then refinance if rates are still favorable.
If you absolutely need to refinance now and you're buying soon, talk to your lender. They can advise you on timing and whether the refinance will impact your second mortgage approval.
## The Bottom Line: Refinancing and Your Credit
Yes, refinancing will temporarily lower your credit score by 5-10 points on average. But the dip lasts only a few months, and the financial benefits — lower monthly payments, reduced interest, faster payoff — can last for decades.
If you're worried about your credit taking a hit, remember: a temporary 10-point drop is nothing compared to the thousands you'll save with a lower interest rate.
The key is timing. Shop for rates strategically, clean up your credit report before applying, and make sure the savings justify the short-term score dip.
If your credit score is already low and you're struggling to qualify for competitive refinancing rates, focus on credit repair first. Removing inaccurate negative items and improving your score by even 20-30 points can unlock significantly better rates — and save you far more than rushing into a refinance with subpar credit.
