Refinishing this floor will remove quite a bit of the surface.

@John DeanJohn, I’ve used both Kilz original oil based (on any surfaces that are real bad/ deteriorating) and then their newer product that is water based called Restorer... most recently (April) I bought a place that had two beautiful dogs that literally never saw the outdoors and after stripping the carpet rolled Restorer on the entire subfloor before throwing down the usual LVP.

On the surface it seems straight forward, however, in my experience anything straightforward is almost always not straight forward. 

Proper water proofing is essential for installation in a wet area, all interior surfaces of the window are DensShielded and Hydrobanned prior to tile.

I toured it but found that it would almost need to be an actual rebuild since the foundation is cracked, the roof has a tree growing out of it, and just about every surface in between is painted or ruined by former tenants.

Even then it should be gravy.On income it doesn't look too bad on the surface.

This material is often actually 2x4 in dimension so when working on a rehab make sure to pay attention to how your surfaces finish out due to the difference in actual thickness and depth.

Lot size, well radii to your well and the neighbors, surface water, boundary lines. etc..

"Lower quality" I honestly would be investing, but I guess semi-gloss if you were really interesting in putting in the labor to wash the surfaces.
