Is Pre-Approval "standard"?

[Lakshay G.]

Hello Everyone,

I would like to get pre-approved for a loan so when I do have a good deal in front of me, my realtor would be ready to make an offer. My question here is Do I have to get a pre-approval from the lender from which I will eventually get/process the loan on the property? Or should I get it from one of banks (PNC/Suntrust Bank) and use that to show other lenders when needed? Does every lender/financial institution accept others' pre-approval?

Thank you in Advance. I am looking for pre-approval to invest in Baltimore County for Buy & Hold.
