Should he have to pay money back?

We were told at the begining of a loan process that we were approved for a loan with 6.9% fixed for 30yrs. He came we signed preliminary paper work, they even changed our mortgage holders with our insurance company, gave them a loan number and everything. We paid his apprasier 350.00 to do the apprasial. Well 2 days before closing the terms changed. Now the loan does not help us at all. Actually hurts. Does he have to reimburse us our money for the apprasial?
