@Tim Hunte Renting my the room is technically illegal in Philadelphia but its just as illegal as doing rehabs without pulling permits.

They noted, while they can technically go to 75%, in recent deals, they are closer to 65% due to DSCR covenants.And maybe this is expected, but I would anticipate having a personal guarantee, fully-recourse loan for retail.

I have a background in lending, have been a Realtor for 25 years, understand creative financing really well...however in all of my asking about this I have not yet found anyone that has successfully closed a subto in a fully legit way.
