@Lou Lee,Remove the carpet, and put wood looking ceramic tile down.   

They are travertine look ceramic tiles..

@Derek Daun,We only do ceramic tile in rentals.   

If you still have any knob-and-tube wiring, it needs to go away.This is where they didn't use cables containing several wires each, but individual wires, and strung each wire around the house on ceramic insulators - kind of like a power line you see on poles alongside a road, but inside the house. 

If you are worried about this the only thing to do that is low cost is ceramic tile. 

Somewhat similar of a job, demo of a few walls on first floor, re finishing the hardwoods, updating kitchen (ceramic tile flooring and cabinets)and bath(Vinyl flooring), little bit of work on front siding, finishing a basement, dry wall anywhere it's needed included, and removing a back enclosure. 

Turns out she didn't like them either and preferred a ceramic tile shower stall.

I usually put ceramic tile in my rental bathrooms for appearance and long term durability. 

Then several years later as the city was upgrading the sewer pipes on the street the contractors heavy equipment literally crushed our old ceramic sewer lines & the basement became a septic tank.

I normally anticipate spending around $5,000 for a new kitchen (new cabinets, counter top, ceramic tile floor, new appliances).
