Shopping for mortgage is okay?

[Andrew Wong]

So I've been shopping around for a mortgage. I just want to make sure that I'm going about it correctly?

I'm currently in contract with someone to purchase a place, and so have been asking around for loan estimates and preapprovals. I don't really remember how it happened, but one of the loaners somehow found out I was talking to another loaner. Felt a little uncomfortable that it happened.

Another thing is that several loaners have said "You have 24 hours to sign this form!" 

My question: I'm doing the sane thing right? Is everyone out to get more of my money?
