Proof of Funds for first wholesale deal

[Donovan George]

Hi all! We are working our first wholesale deal. We are stuck on the step of having a POF letter ready before making offers. I have read of besttransactionfunding.com to get a free POF but that makes me a little weary as we do not actually have the funds to purchase the house if we should not be able to find a buyer. I have also read of some using their end buyer's POF but we don't have one close enough yet to do so. Any advice would be appreciated. Thank you!
