When interest rates started to drop in the spring of 2020, my husband and I took notice. We watched as the rates on both fixed-rate and adjustable-rate mortgages continued to slide to historic lows. As more friends gushed about how much they’d lowered their rates and monthly payments, we decided to look into refinancing.

A mortgage refinance is when you take out a new loan to replace your existing loan. The most common reason to do this — especially now with rock-bottom rates — is to lower your monthly payment.

Locking in a lower interest rate by refinancing can save some serious cash in your monthly budget. And those savings add up to a substantial sum over time. According to Freddie Mac, /zigman2/quotes/202741363/delayed FMCC +3.18% borrowers who refinanced to lower their rate or extend the term of their loan saved an average of nearly $2,300 in annual interest during the first quarter of 2020.

But there could be an unintended downside to refinancing your mortgage: Your credit score might take a hit. The good news, though, is that the dip is temporary and your score should bounce back. Here’s what I noticed when I  refinanced my mortgage .

When we started shopping around for rates on a new mortgage — it’s best to get a few quotes so you know your options — we knew that the creditors would check our credit reports. We knew that this would show up as a “hard inquiry” on our reports, which would likely ding our credit scores by a few points.

We learned that even if a few different creditors pull your reports while you’re interest rate shopping,  multiple inquiries while rate shopping  over a short time frame will usually be lumped together into just one inquiry. That way, the effects on your score are minimized.

After locking in a low rate and signing a fat stack of papers, we were the proud owners of a brand-new mortgage. We traded our 30-year mortgage for a 15-year loan at a much lower interest rate, and successfully slashed the number of years we’ll be making payments. I was ecstatic about the money we’d save. But I wasn’t quite as excited about what happened to my credit score.

About a month after closing, I noticed that my FICO /zigman2/quotes/200175312/composite FICO +1.79% score dropped more than 30 points. My VantageScore fell 13 points. These two main credit scoring models consider most of the same factors when calculating your credit score but weigh them a bit differently. The  things that affect your scores  are:

I had a good history of on-time payments, an acceptable mix of credit and the recent inquiries on my report were minimal. Once the new loan showed up on my credit report, the biggest drag on my score was that the new loan’s balance was, of course, 100% of its origination amount.

Unfortunately, when you refinance, the information about how much of your previous loan you had paid off doesn’t carry over. You also likely will lower your overall age of accounts by replacing an older account with a brand-new one.

You can take steps to protect your credit during the refinance process:

For me, and for many people, refinancing to a lower interest rate mortgage is the right move. The money saved over time by reducing the monthly payment or slashing the length of the loan will far outweigh any credit score damage. The credit score dip is temporary, and the numbers should continue to bounce back the more the new loan is paid down.

Stacie Charles has refinanced her Texas home more than once in the 12 years she’s lived in it and experienced a dip in her credit score each time, by as much as 40 points: “My scores dropped as soon as the new mortgage showed up on my credit report.” But she saw her credit scores creep back up several months after the refinances, and they were fully restored after four to six months.

Before refinancing, do the math to make sure it makes sense for you. But don’t let the fear of a temporarily decreased credit score stop you from locking in lower interest rates. Minimize the negative effects as best you can, and know that as long as you continue to manage your credit wisely, your scores will recover.
