It's great but I just have a few questions like if there was poop (human) in the toilets and they were smelling and if there was cat, rabbit, dog etc poop all over the house floors and objects; urine over everything, what would you use to sanitize it or to kill the smell and probably pathogens so that you can start cleaning? 

Animal urine soaked carpet in many rooms and mold in some areas of the lower levels.  

The extra income is nice but it never covers destroyed yard or replacing all the flooring that was damaged by pet urine.

I gave it a good spray with the hose to get all the dried carpet fuzz and old urine off and I think that it's just soaked into the wood now and maybe all I did was reliquify it.  

Dog urine can be cleaned up but cat urine will ruin a house.

Dog urine and feces and vomit are another issue (all dogs can/do have an occasional accident).  

You may want to consider testing the carpet for pet urine.

It was the strategy before and it's still the strategy, rent control only adds hurtles. 

Urine will get under LVP.

Turns out the cat urine had dripped down behind the baseboards.
