Thank you for sharing this, it's opening my eyes to required growth before landlording.RSO could be public urination and then getting lippy with a cop, or violent pedophile...though getting out of jail or worse prison...they aren't the best people to associate with...or to have in a unit.

Who or how am I going to pay for the damages when she moves out and the carpet, pad and floorboards need to be replaced because it is soaked with cat urine?

Everything else has to be refreshed : Floors (carpeted, heavily spoiled and cat urine odor) Ceilings dry-wallWalls dry-wallElectrical is out of date (knot and tube all over, electrical panel needs replacement) Risks: Sanitization (cat urine smell, potential for pest problems)Structural integrity not checked (unable to check in a timely fashion due to deadline)Evidence of water damage on main floor ceiling, extent of damages unknownNo smell of mold in basement but knowing the city history of flooding, this is uncertainPlumbing looks recent but it was hard to be absolutely sure of this assertionThe reason I decided against in the end : too many unknowns.

In Colorado you can become a registered sex offender for urinating in public.

I just talked to the tenants today, they reported:Homeless people urinating, defecating in publicAwful stench coming from the tents Sketchy/mentally ill people roaming aroundThis especially bad since this is a duplex, and both units are rented to large families with small children.

if the cat urinated around the vent, some of the urine may still be down inside the vents.

He had absolutely trashed the property, and it took quite some time to get the smell out from all the animal feces and urine. 

Tell him you'll talk to him after he urinates into a cup you bought at CVS.There are incentives for solar in places, a new roof....no, probably not.

I normally deal with this stuff myself (fox urine, patch hole, etc), but have no time right now.

The dog has urinated on the carpet which will require replacement (professional cleaning did not get the stain/odor out) and possible replacement of the subfloor as well.
