Proof of funds

[Tevin Swain]

Hello my name is Tevin , im a 22 year old college student in philadelphia.  I'm very interested in wholesaling HUDS and REOS and im very thankful to have found this site because im very excited about getting started. The one question i do have it about Transactional or Flash funding. do i actually need to have the actually liquid cash or capitol in my bank account to use these funds? and are these things the same as a proof of funds letter?

Thank you, for your time and i appreciate the feedback.
