I was connected to Quicken Loans through Lending Tree (another big mistake). Quicken Loans only uses a portion of your credit, salary, and financial history information to base their loan information on. They denied me a loan and sent me a nice long letter so that now I have a loan denial in my history.in the letter, they even admitted that they only used a portion of my information to base their decision on. Fortunately, by the time I received their denial letter, I had was already pre-approved with a local mortgage loan company that found me a loan with days. They asked for more paperwork, but it was worth it. Quicken is a joke!
