If the math works out correctly as mentioned by Kleebo151 that he saved $108,000 over the life of the loan, that is a large chunk of money that the rest of the people that do business with that lender have to make up.
He got a 5% discount in the rate (from 5.94 to 5.625%)
Sorry, but this does not raise my eyebrows. I was able to bargain that much with my home mortgage.
