South Florida Loan Pre-Approval Letter

[Veronica Barragan]

Hello! I'm a newbie investor, and this is my first post! I live in DC but I want to start investing in South Florida because my dad is a GC here and is going to do my rehab. I'm looking to either BRRRR or flip a couple homes until I have the cash for a BRRRR.

I understand that it is beneficial to have a loan pre approval letter before starting this process and making offers. I was wondering if anyone had any good tips for getting a pre-approval letters in south florida? 

thanks!
