I'm just curious what various lenders would be looking for in compensation and structure of this deal:Purchase Price: $25,000Rehab/Holding/selling costs: $30,000ARV/Sale Price:  $85,00090 days for purchase/rehab/sale**My questions below are coming from the scope of my view that a HML being a formal institution/group with a bunch of standard terms, processes, etc... and a Private Lender being someone with money, willing to loan it short term, without all kind of formalities(if that makes any sense)So in a HML world, 65% of ARV would be right at $55,000... does anyone does this deal without requiring rehabber to have skin in the game? 

as your primary you should be able to get an O/O HELOC my guess on the move out question would be dont ask dont tell, so residential HELOC's tend to be 10 year term, so I would maybe get the HELOC from a bank you dont do investing related banking with maybe an out of area bank or bigger institution. and set up a P.O. box or a different address to get correspondence from them (totally reasonable in a multifamily) this way when you move that doesnt change, so no red flag for them to call it due.
