The credit scores on many of the consumer based credit sites are not the same as used by lenders. I have seen fellow mortgage professionals refer to them at FAKE, as opposed to FICO, scores. The only way to know if your scores are the same, or even close, is to meet with a mortgage professional. I would not provide a preapproval for a consumer based upon the credit scores from a site such as you have referenced....some mortgage consultants might; however, I have seen substantial variance in score values and would not consider misleading either consumer or real estate professionals. Best to you!
