Lots of good paying jobs that are insulated from economic and market fluctuations. 

Another route to insulate yourself would be purchasing the note with a payment due upon you successfully foreclosing.

For instance you could hire a carpenter that can get your cabinets, roughy framing and drywall done but they have to hire out insulators and painters while typically adding 10% on top of their price. 

It was a grind to get there and will be a grind to get to where I want to be (which is transitioning to being a broker at CB and owning a couple of rentals to remain insulated from the inconsistent paychecks when being a broker) but when surrounding yourself with the right people has made those goals more within reach.

Then they will inspect framing, insulation/Vapor barrier , amp final inspection.

Removing all interior plasterboard, ceiling, insulation and kitchen/bath fixtures. 

Insulation.

Do you have any insulation in the attic because I am sure that is now growing mold and needs to be replaced.

Hey gang'Got a comment and opinion on PEXIve been a licensed plumber with a Calif CSLB license for 30 yearsHeres the skinny on PEXIts plastic [duh] hence your tenant can drill a hole in it when putting Grandmas picture up in the hallway,,,,Rats can hear water running in it and the can smell,,,hence,,they eat it,,,It doesnt lend itself to insulation,,,,,It cannot be used as and electrical groundA proper copper repipe will last for generationsI wouldnt put PEX in my mother in laws house,,,,,,JMHODave DoyleLos Angeles

For cold zones behind walls and not proper insulated you can use a thermal image reader.For leaks you use a moisture meter.Active leaks will register above the required safe threshold.As you get closer to the leak the moisture reading will be higher.How do you know the GC did everything above board??
