POF Letters, HELP !!!!!!!

[Ashley Swift]

WHERE can I get a proof of funds letter without using my credit. I am attempting to put my first wholesale deal under contract but am having a hard time finding a proof of funds letter to get through the first step of the REO property. I keep seeing the word "blanket" but am not sure if that is what I should be looking for. Also Is there a way to use my end cash buyers funds as the POF because I am planning on closing via land trust? I thought the whole point of "wholesaling" was to flip the property without using your own funds? I found an amazing wholesale reo deal and would really like to find a way to wholesale it. (HELP!!!!)
