The pandemic has impacted the finances of many Americans — some good, some bad.

Focusing on the positive here, national mortgage refinance rates have dropped to near-record lows. Since March 2020, the Federal Reserve has cut interest rates twice to help the economy. The result is that mortgage rates have dropped to the lowest seen since the 1970s.

If you're looking to save a lot of money over the term of your loan, you may want to refinance your mortgage. Credible can help you compare mortgage rates and lenders for free.

If you're considering a refinance option, research the impact it could have on your personal finances (specifically, if refinancing hurts your credit score). Here's what you need to know.

How does a refinance affect your credit score?

A mortgage refinance can potentially affect your credit score. When you compare rates with lenders, they’ll likely check your credit score to provide you with the most accurate offer. If you obtain multiple rates, you could have your credit checked multiple times. You’ll want to find out if the lender performs a hard or a soft inquiry.

A soft inquiry won’t impact your credit score. It is only visible to you on your credit report. In fact, creditors are pulling soft inquiries on you often when they send credit card or loan offers to you in the mail. A soft inquiry also happens when you check your own credit score or if a potential employer does a background check on you.

If you’re simply checking rates during your consideration process, be sure to choose lenders that offer soft inquiries, as not all banks and credit unions do. It’s important to visit a site like Credible where you can get prequalified for mortgage rates without impacting your credit score.


A hard inquiry, however, will affect your credit score. It is visible to creditors and stays on your report for two years. Hard inquiries are reported to the three major credit-reporting agencies: Equifax, Experian and TransUnion. This type of inquiry indicates the number of new credit applications you’ve completed. They lower your credit score and only account for around 10% of your number. If you have too many hard inquiries, you may look like someone who is applying for several loans, and a lender could consider you a high-risk borrower.

The 45-day rule

While you want to limit the number of hard inquiries on your credit report to protect your score, under the latest FICO scoring model, it’s good to know that multiple credit checks from mortgage lenders within a 45-day period are recorded as a single inquiry.

The best way to start your mortgage refinancing process is to avoid accepting the first offer you get. Visit a site like Credible where you can shop around and compare mortgage rates from multiple lenders and not impact your credit score. While a hard inquiry may save you money over the term of the loan, it’s best to choose the options to protect your credit score, as well.


According to the Consumer Finance Protection Bureau, lenders understand that you’re only going to obtain one mortgage or mortgage refinance, and you likely want to shop around for the best rate. The impact on your credit will be the same no matter how many lenders you check. However, it’s also important to know that the 45-day rule only applies to credit checks from mortgage lenders, and not to other forms of credit, such as credit cards.

If a credit check could move your credit score in to a new range — such as poor, fair, good, and excellent — you might want to pull your credit history before starting the application process. Or ask to be prequalified by a lender. Prequalification involves a soft inquiry and provides you with an idea of what kind of rate you can get. However, being prequalified doesn’t guarantee you’ll get a loan or a specific rate. Instead, it simply provides a guideline for those who want to start their search.

Today's mortgage rates

As of October 8, 2020, Freddie Mac lists the average rates for a 30- and 15-year fixed-rate mortgage as:

30 year – 2.87%

15 year – 2.37%

Depending on when you purchased your house, it may be time to consider refinancing your loan. Your first step should be to visit a site like Credible where you can shop around and explore your mortgage refinance options by comparing rates and lenders. But it’s also smart to understand what can happen to your credit score when you start the refinancing process.
