A hot water heater one year, a HVAC unit one year, repainting parking lot one year, that sort of thing. 

Costs to clean and repaint, etc., in-between guests?

Lets see if the checks keep coming but in the meantime this is found money and he has paid just under a third of the bill for completely repainting the unit.

Maybe a different color in the bathroom if you will use a higher gloss paint.You want to minimize how much paint you have around, make it easy to repaint as needed, and spend less time switching colors.  

I prefer flat because it's easier to apply. 99 times out of 100 you're going to have/want to repaint a unit when someone moves out anyways.

Some landlords will bulk at replacing a window pane just because of a tiny crack in the corner or repainting a peeling window sill.  

The entire place had to be re-painted, and I had to wash every wall and ceiling to even get the paint to stick.That being said, I am a smoker, I haven't smoked indoors in 10 years.

I cleaned the mold off the walls with bleach water, repainted the lower portion of the wall and asked them to keep the furniture away from the wall.

I can't really see the condition of the floors or walls because she had them repainted and plastered with decals and posters.

German roaches were even crawling out of the fridge door seals, and had developed language skills they were that advanced.In my wife's defense, she had her crew in, cleared, cleaned and repainted the place before I managed to get back into town. to this day I haven't seen the photos.
