Plumbing, GFCI outlets, tile backsplash, etc.? 

It's not going to be a problem, ever.The only thing to be careful about when you find random PEX fixes in an older houses, usually in an exposed basement, is the chance that someone grounded power outlets to copper or steel water supply lines up on another floor in some random remodel way back when and these outlets lost all  grounding when the PEX went in.

If you need assistance with purchasing homes in Kentucky once you have everything sorted out, let me know.

I'll also start putting up ceiling fans and light fixtures, as well and replacing switches, outlets, and covers.We will hopefully have this one finished in about a month.

Or sell and cash out?

@Jim Windgassen  Everything about making accommodations for a level two charger you state before "existing 240 V outlets" I would strike.

The framing is most likely rough cut so the drywall will need to be floated, when the walls come down you need to upgrade the electrical since I can also bet the electrical is not properly insulated, you need GFCI by sink, you have to have an arc fault breaker on the bathroom outlets and switches and those need to be on their own breaker by code. 

This would only apply to landlords who own more than 50 units, which accounts for roughly half of all rental properties, according to the news outlet.

For example 7 years ago in my town of Flower Mound similar to Frisco but without highways & major employers a house could be had for $150k not new but older & needing some updates.

@Brian GarlingtonHey Brian I have been looking at Holton-Wise you tube videos and I really like the numbers they put out.
