You can also use it for taking up the cement backer board, if that's what you have.

The owners put 3 inches of cement into the basement and put two systems in.  

I also think that the cement around the pool needs to be replaced. 

If it is a concrete slab your are working with, then self leveling cement will do the trick.

Not that you want to intrude on tenants but any smart/competent (from my perspective) PM would love face-to-face visits from owners to build rapport, cement relationships, etc. so that they can keep the business.

Yes, do it now because doing it later will coat your nice clean bedroom with wet cement dust.

However he said lumber, cement, sheetrock and most building materials fly off the shelves at amazing speed and it average out to 8+ minutes, and their goal is to reduce that number even more, and usually by phasing out stuff that sits and stocking more stuff that sells and if that's true eventually there would be zero variety.

Everything was fine for over three months until last Saturday when they fell off the wagon, started drinking again but instead of staying at home they decided to take a ride in their pickup truck.The result was damages to another tenant's car and two cement block walls having over 20ft damages each.

You can choose a regular cement based grout which is about $14 for a 25lb bag from the big box store and that will cover your two bathrooms, its certainly the least expensive option. 

In fact, there was a dirt/weed area in their yard that they wanted covered with cement to put a glass table and chairs.
