They will offer you a better rate than anyone else, charge you a $500 non refundable fee, then ignore your emails for weeks. Once rate goes up, they will tell you that you need to pay them $10,000 for them to honor the rate they initially offered. None of their initial disclosures are binding so they can do this scam in total impunity. I hope my loss is your gain, and that you will select a real mortgage company for your refinance needs.
