In other words, don't worry about if it's too late to acquire 1000 units and go buy a yacht with the residual income.

I would also want to be VERY certain there wasn't any white, powdery, residue on a stack of cash, and that the bills are real!

It's all about the residuals that suck the franchisee dry.

I use mastic (tile adhesive) to float tile grout lines or unevenness and just use the peel-and-stick over top of that once it's flat, dry, and clean.

Two or more layers of shingles are not ideal, even if they use more nails than they should, lacking of adhesion to plain wood or the film layer before the shingles (water shield or decking protection felt) is gone.  

IF the turnkey provider also has a PM company, then the residual income in management fees is one revenue source.One thing I have found from some turnkey providers (I don't say all because I haven't talked to all obviously) is that they buy properties for what could be pennies on the dollar, pour money into rehabbing, and then sell at a premium...so they're fix-and-flippers.

(I can't really spend a lot of time/energy fixing up a place, and can't afford to buy locally - but I need to start generating some residual income and soon.

Turnkey rental is more passive then rehabbing and flipping, residual is more accurate. 

The tile was more expensive than I usually use it was $8/sq Total $232, Muscle bound adhesive 2 rolls (Lowes 26/roll) Grout with sealer (Lowes ) $35.

We flew over in 2016 (my first time coming to the US) and Started all over from scratch in 2016 with $70,000 in his bank account only (residual settlement left from court proceeds).
