Getting Pre-Approved For Mortgage Loans

[Timothy Stieffel]

Hello BiggerPockets Community!

I am about to start the process of shopping for conventional loan rates and getting pre-approved, but am concerned if I shop too much within a short time period it will adversely affect my credit score.

Does every loan inquiry during the shopping process negatively affect your credit or is there a "grace" period after the first inquiry? If there is a "grace" period, does anyone know how long it lasts or does it vary? 

I'm sure this is one of those basic/beginner type questions, but I figured the experts at BiggerPockets would be able to provide some good insight on this issue. Also, this will be my first real estate investment, and I am just wanting to ensure I am considering all factors going forward. Any input would be very much appreciated!

Tim.
