No longer approved for mortgage loan because of sudden drop in credit score!?I was approved over a month ago for an FHA mortgage with a middle score of 628. We found a house, made an offer, and it was accepted, so we got all the paperwork going and everything was looking great. Until the bank just suddenly stopped communicating with me, and seemed to be taking FOREVER with their "paperwork". After a couple weeks, I called to ask what the heck was going on, and was informed that my credit was repulled because the bank made an error on my birthdate, and my scores had "plummeted". My score went all the way down to 593. I had no idea how, but my LO told me it was because of my handy dandy carecredit card I had opened up about a month prior. The card had a $1,000 limit and I opened it to pay for wisdom tooth removal. I have been making the minimum payments on it, and hadn't missed a payment, but my LO advised me to go home and try to get it down to 50%. So, I ran home and made a $500 payment on it. (The current balance is now like $430, and I will have no interest as long as I get that paid off by March of next year.) My LO felt very confident that making that payment would improve my credit score, and get me back on track to getting my house, so she did a "rapid rescore" and expedited proof of my payment to the bureau. Well, I finally heard back from her yesterday and my rescore is only 604! What gives!!!? That card is the only change I've made to my credit, and opening it lowered my score by like 35 points, but making such a huge payment only raised it like 10??? I don't get it. I am very stressed and confused, and losing hope. I am going to the bank to meet with the LO Monday to find out what the heck is going on. Does anyone have some insight or advice? I am lost.Thanks.-EDecember 01 2012 - US00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
