Would like to fine some single family house to rent.

If they are still working and have enough lead time (3 months given the current situation), it should be fine.

The couple you mention sounds like they could be just fine.

Some turn out fine..........others not so much.

Leverage is fine for some, but I want to stay in this thing for a long time and want to be sure my strategy works in the good times and in bad.

You are paying a finders fee basically.This is fine. 

For your "average" residential home, doing it under your own name (not even really a sole proprietorship) is fine with insurance and an umbrella policy. 

They're just not going to come to South Lake anymore - hell, they've already been clobbered with $1,000 fines for unloading luggage in the wrong place, or being in the hot tub at 10:01 PM. 

If I wanted a full appraisal I could've got it, but paid the extra $400 or so.Helocs have more fine print than a regular mortgage. 

For example, I have clients that won't take below a 12% ROI with a light rehab while I also have clients that won't do value-add so they are fine with a 8% cash on cash return.
