@David Benton  our market in PDX were listing basically are money in the bank.. commission have dropped.. rare is a full 6% on almost any home.and in Charelston I am at 4.5 to 5% all the homes I am building here sell prior to completion and it has not been an issue.. no doubt some grumbling because of old standards of pay. 

I have a pretty sensitive nose, so for me this is the process to eliminate just about any smoke odor:1.

After de-catting and de-dogging several units from the odor, fleas, hair and damage caused from urine, feces, scratching, digging.

Before replacing it I had it cleaned professionally but odor remained.  

I’m already paying $60.00 per door and grumbling about that.

I honestly don't think you'll get a contractor, painter to GUARANTEE they can get rid of cat pee odor, if the apartment has been abused for that length of time.

Laminate was wet underneath in about a 2 foot area around that sides of the opening and when he pulled up a couple of pieces of the laminate there was a strong urine odor. 

I have a condo unit in Southern California that I recently rented out; however-- on the first day the tenant moved in, they notified me that they smelled a strong cigarette odor in the hallways, and it really bothered them.

Usually the fines are for "Noxious Odors in common areas" or for excessive noise.  

The biggest issue they had was the spouse grumbling about the living conditions in each of the new houses.
