Hard money to buy from wholesaler?

[Bill Goodland]

I've been browsing some house-hack and investment property listings between MLS and craigslist FSBO in Philadelphia. I have a fairly good understanding of the neighborhood and rental markets in philly but it seems like any deal worth having is a FSBO listing, most likely from a wholesaler wanting cash. My question is, is it possible to use hard money to pay "cash" for a deal, then refi out with a conventional mortgage at 75-80% LTV? I have heard about this being done as part of a BRRRR strategy when a rehab is included, but what about if a significant rehab is not needed and more of a lip-stick rehab while you live in it? Does it make a difference if it is owner occupied when thinking about a "seasoning period" with the bank?
