Sometimes, the city nails us for lead testing in ceramic tile walls, floors and bathtubs. 

Ceramic tile is also good though the grout is a weak spot for odors/accidents.2.

After my first tenant turnover I added ceramic tile in the living room and hallway, painted the whole house, and replaced all of the windows in the house.

So far, all I have put in my fix & flips has been ceramic flooring.

Get a 4 mm thick click lock vinyl wood look with no less than a 12 mil wear layer and make sure it has either an aluminum oxide or ceramic bead finish for scratch resistance.

BTW, IMHO, replacing vinyl sheet floor covering with ceramic is an upgrade; replacing a rotted bathroom floor, or painting when it's needed are NOT upgrades--they are basic maintenance issues.Good luck with the cat lady.

I have a little dream that includes retirement in a place where the mountains meet the sea, a lot of writing, some educational charity, a nice shop out back with good tools in it for me and a nice adjacent ceramics studio for my wife.

Looks high end and costs less then ceramic and hardwood and is more durable then laminate.Item pictured is a floating floor application that locks together, requires no underlayment and goes over floors that are fairly uneven. 

She liked to be on her barefeet in the meantime, ceramic/porcelain seems not pleasant (rugs on ceramic might slip?).
