I work as a lead product manager at Lumen technologies. 

I haven’t used grip strip but have had bad times with other adhesive flooring products.

I've personally experienced how much of a difference doing property management well makes versus doing it poorly. 

How it was handled is messy, poor docs, potential fraud from owner forging end buyer signature without consent, no paydown financial logs(amortiz table) on the REC since there was no escrow company involved so the payments were going in direct to seller account who was not paying property taxes and the tenant is getting burned on this deal.(2)The contract almost non existent or sketchy at best.

Heard some concerning stories about turnkey providers providing very poor properties that are just "lipstick on a pig?"

I don't know about any movies....books are the best option IMO.Rich Dad, Poor DadHow To Invest in Real Estate (BiggerPockets bookstore)Read a book on flipping, a book on long-term rentals, a book on short-term rentals, and a book on multi-family. 

I doubt any replacement builder would commit to timeframes as there's a lot of variables and several unexpected product shortages.

I've been in investing for more than 20 years I'm also a broker so I've seen firsthand the problems that poorly educated / trained agents have on this profession.

I'm particular to that book as that was the very first REI book I read (minus Rich Dad Poor Dad) and it really opened my eyes up to what is possible.
