Ask how old the roof is, when the HVAC systems were replaced, and whether there have been plumbing, electrical, or water issues.

Finished rehabbing one of my rentals and needed electrical work done so I had an outlet placed in a location with a wall mount TV in mind.

Hi, I'm looking at a property that is technically a manufactured home built in 1963, but has been completely remodeled with updated electrical, plumbing, and a entire stick-built house built on to the original single-wide, which basically only retains the original walls.

Yes, I'd highly recommend Woith Civil Engineering if you're doing any ground up development in Montana.

How old is the water heater, AC system, and electrical panel? 

Should the electric service panel be replaced?

I already have 50 auto pay bills that I'm gonna have to call each stupid company and swap over to the new bank acct; or spend 10 minutes trying to figure out the passwords b/c we all know with the electric company, if you don't have a two-factor authentication, you run the risk of someone else paying your light bill right?

A few things I'd look at.... 1) Wiring, electrical panel.

An engineered cost segregation study doesn’t require REP status to be valid, it simply accelerates depreciation but whether you can use the losses immediately depends on how your activity is classified.

Electrical is of course useful in working hands-on with real estate.
