Credit scoring is one of the most misunderstood factors of mortgage banking. The algorithms that go into it are complex in nature and to make matters worse, there are actually 49 different FICO (short for Fair Isaac Corporation) modeling scores available. Fannie Mae & Freddie Mac only accept 8 of those scoring models, so many times when consumers are getting their scores online, they are getting a less conservative FICO score than the agencies will accept. In some cases, these models can be based on a completely different scoring system. Therefore, most times when your New Jersey Mortgage Lender runs a credit score, the scores will be lower than what consumers are pulling online for themselves.
