The FHFA – the federal regulator for Fannie Mae & Freddie Mac -- set out new guidelines for interest rates and one part of the change has certain consumers with lower credit scores qualifying for lower interest rates than other consumers with higher credit scores. Someone with a 640 credit score in essence will qualify for about ¼% lower in interest rate on a 30 year mortgage than someone with a 740 credit score. This is flat-out wrong! How does this happen?
