My wife and I bought a house last April, and while we were going through the house buying process, I was curious about the role my credit score would play in getting the mortgage and how it would be affected once we got the mortgage.

Of course, I know you need a good credit score to be approved for a mortgage, especially in the current economic climate. But I didn’t know if getting a mortgage would have a major impact on my credit score. I was surprised to see that my credit score wasn’t affected very much at all.

How much does a mortgage affect your credit score?

I’ll show how my credit score was affected once I got the mortgage, and how it looks almost a year later. This is based on my personal experiences, and there are literally hundreds of factors which can go into your credit score, so your mileage may vary.

Before jumping in and showing the actual credit scores before and after our mortgage, I think it’s best to look at some of the factors which explain how it works and what changed in my credit profile. Let’s start by looking at the big picture, then work our way down.

Understanding your credit score

This graphic is from the MyFICO website, and it shows how the factors are weighted for your credit score. So the makeup of your credit score before you apply for your mortgage will help shape how your credit score looks after you get your mortgage.

How is Your Credit Score Determined

Tracking my credit score

There are several ways you can track your credit score. Before we got our mortgage I started using a credit monitoring service out of curiosity – mostly I wanted to see how they work and what they track. I signed up and got a copy of my credit scores based on the three major credit bureaus (Equifax, Experian, and TransUnion).

Getting Your Real Credit Score

Many people say that you should get the FICO credit score directly from MyFICO. This seems to be the obvious option since FICO is the company that creates the scores.

However, you can get your score for less by going through FreeScore360. They offer you a seven day trial and then it is only $19.95 per month going forward, which includes all three of your credit score, credit monitoring, and $1 million of id theft insurance.

Credit Score Alternatives

For my purposes, a score based on the major credit bureaus was good enough as it was for personal reasons only, not for a specific loan.

If you are looking for an absolutely free credit score (free as in, no credit card required, no trial period, etc.), then check out:

These aren’t the FICO credit scores, but they are based on information from the major credit bureaus and are accurate enough for personal use.


Just applying for a mortgage, or any other loan can affect your credit score

Applying for any line of credit, including a credit card, car loan, or mortgage can cause a drop in your credit score. The change in your score depends on many factors, including the type of credit you apply for and how many lines of credit you apply for in a time period.

A typical hard credit pull can lower your score by 2-5 points, which usually isn’t enough to make a major change in your credit score.

How a mortgage changed my credit score

The following credit scores are mine from various times last year. You can see how applying and being approved for a mortgage changed my credit score. The January credit scores were taken at the request of our landlord to prove we were creditworthy (we had a short term lease before buying a home).

The April credit scores were taken when we applied for the mortgage, but before the mortgage closed (we closed about 2 weeks later). There were no other credit applications or credit pulls during that time.

The December credit scores reflect our credit score after our mortgage had been active for 8 months, and after I had opened a new line of credit (a credit card with a $25,000 limit <<— no, I didn’t ask for that much, they just gave it to me. I would have been happy with a $5,000 limit!).

Jan 17, 2011 (before applying for a mortgage):

  • Equifax – 803
  • Experian – 801
  • TransUnion – 798

Apr 1, 2011 (immediately after a mortgage approval, but before closing):

  • Equifax – 792
  • Experian – 777
  • TransUnion – 795

Dec 28, 2011 (8 months after mortgage became active):

  • Equifax – 811
  • Experian – 796
  • TransUnion – 788

Checking Mortgage Rates

If you are in the market for a new mortgage, these are some of the best lenders available.

Takeaways from applying for a mortgage

Multiple credit applications may or may not hurt your credit score. It’s always a good idea to shop around for mortgage rates when you are buying a house, and the credit bureaus realize that people are going to shop around.

So multiple mortgage inquiries in a 45-60 period may only count as one credit inquiry, and shouldn’t affect your credit score too much. But you might see a larger drop in your credit score if you are also applying for credit cards or car loans at the same time. It’s best to secure your mortgage before opening other lines of credit.

Multiple lines of credit in a short time frame may not hurt you. While you should always secure your mortgage before applying for new credit cards, car loans, or other loans, opening a credit card after your open a mortgage might not hurt you.

In fact, the credit simulator at Credit Karma showed that opening a credit card with a $10,000 line of credit would actually improve my credit score, even though it would decrease my average age of credit and increase my credit limit. This seems to have been the case, as I opened a credit card in early December in my credit score has improved.

Your credit score might go down at first but should rise after awhile. Getting a mortgage will most likely cause your credit score to drop – but that should be a temporary event as long as you make your mortgage and other loan payments on time.

Your score should rise after you make payments on your mortgage for a few months. In some cases, your credit score may end up higher than before you got your mortgage. Again, it all depends on the specific factors affecting your credit score.

You might expect to see something like this:

  • Expect your credit score to drop a few points when you apply for your mortgage
  • Expect your credit score to drop a little more when your mortgage is approved
  • Your credit score will stabilize
  • Then your credit score should begin improving, provided you make all loan payments on time (all loan payments including your non-mortgage debt).

Your results may vary. As I mentioned earlier in this article, your results will depend on many factors, such as your credit history, payment history, the total number of lines of credit, the average age of credit, and other factors.

  3. Monica says

    We just purchased a house but still haven’t closed, waiting on the underwriter. My question is our credit scores were high before we got our loan, now we are about 3 weeks from closing and our scores have dropped drastically, would this cause our house not to close even thou we got approved and signed the contract

    • Ben says

      Monica – yes that could effect the final approval of the loan and you should definitely start that conversation with your lending agent as soon as possible. What happened that your credit “dropped drastically?”

      The way it works is the lender pulls your credit for pre-approval, this is good for 90 days and the loan offer is based on that, but your credit will be pulled just prior to closing as well to ensure you still qualify for the loan. Until you have your mortgage and close you don’t have a mortgage and general best practice is to treat your credit score as carefully as possible during this time.
