prequal letter

[Chad V.]

Looking to wholesale REO properties while I wait for my rehabs to sell. I know there are websites out there that will issue prequal letters in a matter of minutes but what happens if I can't find an end buyer in my 45 days. Does my exit letter (unable to get financing) have to come from the same place or are there websites that will issue these also. I am lined up with a local investor friendly bank but I am trying to exercise other options as well. I am new to wholesaling and any advise would be greatly appreciated.

Thanks,
Chad
