Choosing a Lender/Mortgage Broker

[Account Closed]

I've gotten a few good faith estimates (one from a Mortgage Broker and one from my local Bank of America). The BofA rate was 6.25%, at a 30 year fixed for a loan of 200k (1.07 points). The Mortgage Broker rate was 6.75% at a 30 year fixed for 200k (1 point). Obviously, it looks like the BofA rate is better (my friend commented that he's surprised that the bank had a lower rate of the broker). Is there anything else I should be looking at in my good faith estimate or are these numbers the main numbers I should go on when choosing which lender to use? Also, I know I need to interview mortgage brokers, does the same apply to bank lenders/officers? Thanks for any advice!
