However, these properties generally have a lot of land improvements that qualify as well as certain portions of electrical, mechanical and plumbing that can qualify.

I understand that a GC is suppose to have subs, but this was work I had contracted with HIM, it was not electrical or foundation work that needed to be subbed it was to him and I was under the impression he was the one working.

After catching the investing bug, I flipped my first property and turned it into a rental—which I am still renting today!

The need for building permits in the counties is limited to plumbing, HVAC, & electrical. 

It's not realistic in most cases because warehouses are built as that, which means they run much less electric and plumbing.

I like the 'method' where the tenant puts a check on the inside of the electrical panel.

I don’t worry about the electric because I use that for short term rentals.

A small bathroom can be gutted and drywalled new tile new electrical new shower everything in five days or 40 hours. with two guys. 

In the northeast having a second heat source in the rental saved  frozen pipes when the electric was out for days.

For example: Landlord will pay for electric, water and sewer charges up to $100 per month.
