When I get back home I will activate my signing service accounts both with NNA and snapdocs.com, I hope to cut my teeth on a few jobs that way.

As easy as this sounds, it's not simple and usually like pulling teeth.

1st of all I’m doing a cash out refi you are taking on 7% debt so any investment’s would need to get more than 7% a tough task for anyone, an especially tough if not impossible task for an older person who should take on much lower risk than a younger person. 2nd let your father enjoy his golden years with as little stress as possible, sell the house, buy something in cash wherever he moves, anything left goes in to t-bonds or AAA debt.

This is such a low payment that you could put the rest of that downpayment into US treasury bond and it will cover the PMI expense and more. 

Do I need to be bonded/insured if I require the contractors to be bonded/insured?

Everybody cuts their teeth that way around here.

i-bonds (a savings bond) get a lot of press when inflation is flying and are about the only tool that will approximate inflation (https://www.treasurydirect.gov...), but that's not guaranteed.

It was a little bachelor apartment in a 30 unit complex, according to the add it was currently rented and the tenant was willing to stay on and the ad proudly proclaimed: "Rental covers monthly bond!"
