The wood actually looked like it had an oil stain.

@Bob Mazza, I agree with much of what others already posted here - oil stains on the carpet and globs of grease caking walls, stove, floors, etc. is NOT NORMAL WEAR AND TEAR.

I suggested a MIXTURE of vinegar and water to clean,  when she complained that it has " mold" looking stain in the shower head.

That's the only thing I'm dead set on with the plumbing and marble budget.I would do ceramic tile all over and seal every year or so, or stained/sealed concrete if you can.I also use 20" ceramic tile for my counter tops with a painted/stained wood bullnose.  

I think for the carpet she has a legitimate reason to take your 1400 though over 5 years you might argue it should be replaced regardless of whether there are pet stains due to ordinary wear and tear.  

However, they left countless holes in the walls; stained carpet which had to be replaced ... and here's the kicker--- they used Liquid Nails to glue every single window shut in this 2 BR apartment! 

They don't stain, never need to be sealed, don't chip/crack as easily as granite, and if you pick them well no one can tell the difference from real stone.

Sad.I would suggest texting him/her your intentions for record and finding out the laws in your state and if you have the time and stubborn personality like I do, fight it.      

that garage is an eye sore. need to tone that down. do this:add shutters to the front window, match that color with the garage and front door paint. it needs one mature plant, ideally, something with color (blue evergreen garden variety (dwarf size). nice buy. ideally, garage door could be made to look like a wood stain, and shutters match.

Any time their is any sort of stain or smell, I always run the expense BIN Shellac primer ....
