He urinated on himself the floor and his room was filthy.

After done renovations / repairs / maintenance on many many properties, I kind of know the price range of each job like painting, flooring, drywall, plumbing, electrical, AC, pest control, remove odor from old pet urine, mold remediation, cabinets, countertop, backsplash, appliances etc etc in my mind.

(Some neighboring landlord or guy that owns land a few miles away)... then, he can really go "urinate up a rope".

First time my place was trashed by some festival goers (puke and urin on beds, beer everywhere) and my maid cleaned up and disposed of the trash before airbnb told me I needed to take photos. 

It is almost as sexy as cat urine but still pretty sexy. 

@Joel Florek the living people are the ones you need to be concerned about infecting you; no special cleanup is necessary, there may be a small amount of discharge (urine/feces) after someone passes.

If you've got enough damage to bring the price down that low, then it is a major job, and the permitting/paperwork/inspections needed to get it back up and running could be the biggest hurtle. 

I had my handyman put a quote together to replace the existing carpet due to the cat urine and it came out to $1900 for him to do it.  

The tenant agreed to leave the day for the court date, remove his belonging and give me the keys if I didn't go to court and get a judgement.I cleaned the place out, have spent 3 solid days getting the dog urine smell out of 2 rooms. 

Probably the biggest concern for me is chewing or significant urine damage requiring changing out the entire carpet.
