So, I'm just removing the fixtures, closing up the holes and repainting, and carpet/tiles.

It looks like you have a nicely tiled surround, and guests will want to see that it’s been modernized. 

I will do a significant part of the renovations myself with previous skills developed (framing walls, running wires and finished electrical, laying the vinyl myself | drywall, texture, two exterior window installations, sawing out the tile for the wall, and hanging one door will be done by someone else).

We targeted C class properties that needed some work to get started.  3-4 years ago (when we were buying heavily) this took on average about $30,000 to close on a deal, and then we would spend maybe $5,000 polishing up the place (new carpet or tile), and maybe some new paint.Today it’s probably tougher to find that deal.  

The LVP is more of an insulator than tile.

Inside I have done painting and new flooring, bathroom tile cleaning and grout as needed etc.

The main difference is the internal parts that are more often brass or ceramic valves that are meant to run for thousands of cycles and have warranty to replace any faulty cartridge parts. 

We are looking for local suppliers for flooring, tile (floor & backsplash), light and faucet fixtures, etc. for an upcoming rehab and would love your tips.  

Last year saw a new hardwood / tile floor in the living room, a remade master bedroom and a brand new hot tub. 

Using a 5 gallon paint bucket and sponge mop with Tsp and a rinse bucket with a big tile sponge to rinse, you should be able to hire unskilled labor to clean.
