It sounds like your problem may be your credit score. I have never heard someone say you can not get a loan because of inquiries! Now granted too many inquiries on your credit profile will pull your credit down so dont let anyone else pull your credit for a while! As far as getting 15points, if you have more than one credit card, pay them down as much as possible and you will get your points. Do you know your credit score? If you scores are under 640, you may want to get a secured credit card for $500-$1000 and when it hits your credit report you will get about 25 points.. Good luck
