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).

You do what you can to LIMIT your exposure to that risk, via identifying and controlling those risks, but there will ALWAYS be some residual risk that you're taking on - with ANY investment. 

.$4100 for  rent and chaild care on tax home of  alittle of  6K  doesnt  provide much residual income per month ...if you make it work - great and  good luck

Furthermore, the goal is for those 20 doors to produce an additional $30K+ in residual income for me. 

I was looking to buy a couple multi families and have a residual rent be income to me whilst living free.
