If the concrete floors are not perfect, you can always have your tile guy use a self leveling cement before you install the tile. 

Mine is a walk-up only and the laundry is down the stairs in a basement, and therefore there is no one to accommodate ADA style.

Thing is, it really doesn't offer the protection that people perceive...your LLC won't help you if you hit someone in a cross walk...or if your tenant falls down the stairs and you have enough equity to make an injury lawyer hungry...just do some more research.

A tri level to me is where you enter in the middle level, but there is a half stair going up to one level and a half stair going down to another level. 

But all the original cement walls & flooring were tight without any wicking so the source was in-house humidity.

Maybe removing the stairs would be too much, especially for a college rental.

Same with units on the backside of a building or have to go down stairs to get to.Pay attention to office for that areas saturation levels of inventory per sq ft for lease along with new builds slated and how much of that sq ft is being absorbed in the market (supply versus demand).

I would just sand and repaint the cabinets to a light gray if that is not your style then stair a mahogany color.

I have also put in brand new carpet on stairs and all of the upstairs.

The cement patio had separated from the same type of brick wall you have.
