Does Shopping Around for a Mortgage Hurt Your Credit?

No, shopping around does not meaningfully hurt your credit if you do it in a short window. According to the Consumer Financial Protection Bureau (CFPB), as of October 2026, multiple credit checks from mortgage lenders within a 45-day window are recorded on your credit report as a single inquiry. So there is no reason to take the first offer out of fear of a credit penalty.

1. What a lender's credit check does

A credit check by a lender is reported to the credit reporting companies as an "inquiry." The CFPB says an inquiry typically has a small negative effect on your credit scores, and that other lenders can see it. An inquiry tells other lenders you may be taking on new debt.

Inquiries are a necessary part of applying for a mortgage, so you cannot avoid them altogether. The CFPB's general advice is to apply for credit only when you need it.

2. The 45-day window

The CFPB explains the reasoning: other lenders understand that you are going to buy only one home. Inside a 45-day window, multiple mortgage credit checks count as a single inquiry. The effect on your credit is the same no matter how many lenders you consult, as long as the last credit check falls within 45 days of the first one.

A practical way to use this:

1. Decide when you will start. Do not spread applications out over several months.
2. Request preapprovals and Loan Estimates from several lenders within one stretch of a few weeks.
3. Count 45 days from the first lender's credit check and keep every other check inside that window.

If a lender needs to check your credit after the window closes, the CFPB says shopping around is usually still worth it. The effect of one extra inquiry is small, while a better deal can save a lot of money over the life of the loan.

3. Avoid other credit applications

The 45-day rule applies to mortgage lenders. The CFPB warns that applying for a credit card, car loan, or another type of loan creates an additional inquiry that can lower your scores. It recommends avoiding those applications right before getting a mortgage or during the mortgage process.

4. Checking your own credit is free of penalty

The CFPB says checking your own credit does not affect your scores, whether you look at your report or your scores. If you have not yet checked your credit report for errors, it recommends doing so before you apply. You can get a free copy at annualcreditreport.com, and if you find errors, get them corrected as soon as possible.

5. How to compare lenders

The CFPB suggests starting with a broad internet search for mortgage rates in your area, then contacting banks, credit unions, and other lenders and brokers. It also suggests requesting Loan Estimates from at least three different lenders and comparing them. From each lender, ask for:

• A list of current interest rates for the loans they offer, and whether the quoted rates are the lowest for that day or week.
• The fees the lender normally charges for each loan product.
• The annual percentage rate (APR) of each loan. The APR reflects the yearly cost based on the interest rate plus points, broker fees, and certain other charges, including some closing costs.
• Whether each rate is fixed or adjustable, and what points or fees come with it.

On points, the CFPB cautions you to make sure you actually get a lower interest rate in exchange for the extra points you pay.

6. Questions that make offers comparable

The CFPB lists questions to ask about any loan offer:

• Is the rate fixed or adjustable?
• Do I need to pay points?
• What fees will I pay, and will I pay them myself or will the lender loan them to me?
• What is the term of the loan?
• How much will my payment be, and will it eventually pay off the principal?
• What other costs will be added to my monthly payment?
• Can I repay the loan early without penalty?
• Will payments change over the life of the loan, and how high can they go?
• For an adjustable-rate loan, are the rate and payment adjustments capped?
• How much will I need to put down?
• Does the written offer match what I was told?

The last question deserves attention. Compare the Loan Estimate to what the loan officer said on the phone before you commit.

7. Key takeaways

• Mortgage credit checks within 45 days count as one inquiry, per the CFPB.
• Cluster your applications in a short stretch and count from the first check.
• Do not apply for cards or car loans during the mortgage process.
• Checking your own credit report does not lower your scores.
• Ask at least three lenders for Loan Estimates and compare APR, fees, and points, not only the rate.
