<prompt> Human: Whats the best way to shop around? What should I consider? I know next to nothing about this so any advice would be very helpful. Thank you very much for your help, I truly appreciate it.  <response>: Youll want to compare the interest rate as well as the mortgage origination fees, since those can vary by bank. If you have already been pre-approved for a mortgage, and you know your credit score, you should be able to shop for a mortgage by asking various banks to quote you an interest rate and estimate of mortgage origination fees based on your credit score. You wont need them to run your credit until you have decided on a bank and are ready to close on a house.
