Multiple mortgage pre-approvals and effects on credit score
Johnny.  I recently bought my first home as well, and I have worked in the credit business (not mortgage), so I think I can answer some of your questions.  Disclaimer first that I'm in NY, and home buying does vary from state to state. In my experience, pre-qual is not too different from pre-approval.  Neither represents any real committment on the part of the bank (i.e. they can still deny approval at any point), and both are based on pulling your credit bureau and calculating ratios based on your stated (probably not documented) financial information.  It's theoretically possible that a seller would choose a pre-approved buyer over a pre-qualified buyer, all other things being equal, but all other things are seldom equal. Remember also that you don't need to ultimately get a mortgage from the same bank that you use for the pre-qual.  The pre-qual just shows that you are probably credit-worthy and serves to give you some credibility with sellers.  Once you have an accepted offer and need to find a real mortgage, you can shop around for the best rate and best loan structure.  Banks don't need to have pulled your credit to quote rates, but they will need to have a general idea of your FICO range.  Once you find the bank you like with the best rate and actually apply for the loan, they will pull a hard bureau, and if your scores are different from what you said before, the rate may change, but within the same range, you'll generally be ok.  Also, banks do not necessarily pull all 3 bureaus; they may only pull 1, as it costs them for each pull. 2 potential downsides to this approach: Also, make sure you have a mortgage/funding clause in your contract, as banks are unpredictable, and make sure you have a great real estate lawyer, not a legal "factory" - the extra few hundred $ are worth it. Don't overthink this credit stuff too much.  Find a good house for a good price, and get a no-nonsense mortgage that you fully understand - no exotic stuff.  Good luck!
