In some places you are permitted to install GFCI outlets to provide a work around for not pulling grounded wiring to all receptacles (consult an electrician in the area to see if this is permitted).   

In fact, he's an electrician by trade, and works as one.

Had the electrician come out multiple times and he had told her that she was the problem and not the house (Which she didn’t like), and many others from “health code violations for one of the two bathrooms having to get the plumbing redone and it was an inconvenience to her”.

I personally dont like it when service people - especially electricians - charge "per-point" or per job.

One outlet that does not not work, hot water tank needs electrician to do final wiring.

If a project needs permits, it also needs licensed plumbers and electricians.

Lender's liability is much greater, an electrician or even a lawn care company has greater exposure than landlording a single family dwelling.

If you hear electrical sparks in a receptacle or light switch, let us know and shut the breaker for that room until we can get an electrician out to the property.If You're Locked Out:If you’re locked out, do not force the door or break a window and make it look like a break in so you don’t have to pay for it.

Also, where I'm at there are certain neighborhoods where tradespeople like plumbers and electricians won't go for service calls.If you have a local Real Estate Investing Club get involved and ask questions.

Same with the HVAC and electricians.
