I have checked our FICO scores...which will they go by credit score or fico score, or is it the same thing? Our FICOs are 708 and 720, maybe higher now because we have paid of a couple of things and also took care of some discrepencies on there. Isn't your preapproval only good for a certain amount of time? We aren't looking to actually purchase/close until October. We will fly out to VA in September to look at houses and put in an offer etc. and we don't want them to have to keep pulling our credit and lower it.
