The new tenant noticed it, and I explained there's no tracks on the floor, just some plastic clip guides.

I myself just finished a 200 unit complex on the west side where the soils had a Plasticity Index(PI) of 34.

There are some that use the equity in their property as their emergency fund, as they view the emergency fund to be used for major surgery, septic field failing, boiler fails, etc. 

You can see the gray plastic of the new drain above. 

Plastic or rubber runner, covering almost the whole step.

It arrived in a plastic bag with apologies from the USPS.

Then use chem sponges also referred to as dry cleaning sponges (Quick tip: You can tear them in the middle like opening a sandwich and get double the use out of them and get a pole that extends with one of those plastic adjustable mop head clamps) to wipe everything that's left.

I am planning on stripping out the cheap floors (made out of plastic material) to sand and polish out the wooden floors underneath.

Short answer = if your ROI is good and you don't need a $500K heart surgery, be happy.  :-)

Smaller deals give you an opportunity to be more plastic.
