Your score will certainly be impacted at first. But it isn’t something you should worry about at all. Firstly, you’ve achieved the largest thing that you can ever achieve with a excellent credit-score…a loan on a home. Second, you’re score may drop 30-40 points at first but after a year of on time payments it’ll jump dramatically. Thirdly, there is nothing that will require a credit score that high, (except perhaps another mortgage) and if there is something else you’re trying to get you can now use your home as collateral (seeing as you have 20% equity.)
