Q&A: Finding your real credit score

Dear Liz: I’ve been thinking of buying a house, and I want to get a good deal on the mortgage. To do this, I’ve been working on getting my credit score high. I only have one credit card and have had it for less than two years. This credit card has gotten my FICO score to 788. I’ve never had a loan. Would you recommend getting a credit builder loan, to try to increase my score and get a better mortgage deal? Or is 788 good enough?

Answer: Mortgage lenders typically use older versions of the FICO scoring formula. The resulting scores can be quite different from the free scores you can find online, or even the FICO 8 or FICO 9 scores that your bank and credit card companies may show you.

You can get your mortgage credit scores, along with FICO scores used for auto lending and credit cards, for $19.95 per credit bureau at MyFico.com. (Be sure to click on the tab that says “one time reports,” because otherwise you’re signing up for a subscription service.) Be sure to get all three bureaus’ scores, because mortgage lenders use the middle of the three numbers to determine your interest rate. If your scores are 800, 740 and 720, for example, the lender would use 740 to determine your rate and terms.

If the middle of your three mortgage scores is 740 or higher, you should get a mortgage lender’s best deal. If it’s not, the MyFico.com report should give you some clues how to get it higher.
