New wholesaler - need proof of funds

[Dale Manning]

Thank you in advance for your time! I am looking at getting into wholesaling and using on market leads to start out with. I know I will need a proof of funds letter for this; my question to the community is what is the best way to go about getting this? I would be seeking 100% transactional funding and no guarantee that I will need it (other details of the deal will determine an assignment vs double close) but I know I need that POF and frankly don't have the cash in the bank. Is there a tactic that works best? Will hard money lenders just print off 5-10 proof of funds in a day for you if you need it?

If anyone has a solid suggestion for a way to get the POF in Florida I would be happy to take it!
