There is no typical "Mortgage Broker Fee", they vary from whatever the loan officer wants to carge you . Usually nowadays up to 5% maximum. I was a former broker and know this for a fact. It holds nothing on your location in the US. I work at a bank that lends in all 50 states and would be more than happy to get you a good faith estimate. I can almost garuntee my fees will be much lower. Call me if you want an estimate.
