Help clarifying something please..

[Michael Fitzpatrick]

Ok, probably stupid but simple question here....I've seen on the forums and have talked to some title companies about double closings and assignments etc etc......

When doing a wholesale double closing....I can use C's(all cash end buyer's) funds to fund my(B) initial transaction with the private seller(A). Does it just depend on the title company/attorney that I would use for closing on how the process would go?
I have been told by one company that I would need to bring my own funds to closing and I couldnt use the end buyer's funds....is that in an instance of a short sale in which I would need that? Please help, im trying to educate myself and I guess you would say "work backwards" so I can be able to have everything set up properly.
