You won't be able to use conventional financing and must use a non-recourse loan which typically require 40% down.

Yes you do have to pay PMI when you do this but once you hit 20% equity you can get it removed if you buy with a Conventional loan as opposed to an FHA loan.

Any lender, private or conventional, will have some hoops, maybe just not as many for private lenders...

Conventional How did you add value to the deal?

9) adding multiple ADUs or adding an ADU to a quad looses F/F conventional financing.

Quote from @Paola Astrid: Should I refi to dscr or conventional to remove pmi?

Account Closed said, income and assets are the only "hassle" with a conventional loan.

I'm feeling most drawn to a buy and hold rental investing strategy and like the idea of the BRRRR strategy in tandem with VA loans, basically refinancing VA loan backed mortgages to conventional loans once there is 20% equity in the home.

I’m a broker that has access to conventional, non-QM, and hard money loans.  

That is important when considering a conventional conforming loan.
