You got past the first big hurtle in real estate investment, signing up and reaching out in BiggerPockets.

In San Francisco, an individual who is caught urinating on the street by the Police can be arrested and will have to register as a sex offender.

My wife is hell-bent on tile, but that is more costly and I'm concerned about maintenance and safety (especially in the bathrooms and kitchen...urine stained grout and cracked tiles where tenants drop their cast iron pan on the floor...eeek + slippery when wet!).

Getting into 6-7 loans in your first year is like blood-doping for months and hiding a rubber bladder of dog urine under a merkin for the drug test at the end of the stage.

@Scott Trench as far as those cats, hopefully you are inspecting to make sure they are not urinating in the property.

When he flushes the toilet, often his toilet is overflowing and urine and feces liquid is coming through the ceiling through the bathroom fan and dripping all over the toilet and the floor.This has happened and been documented 4 times, that I'm aware of as certainly it happens when i don't happen to be here. 

There is pet urine and feces throughout our home to the extent that we are going to need to replace multiple baseboards and some sheetrock and all the carpet in our home.The garage door has been backed into and knocked off its track and broken.The landscaping in the yard is completely dead, driplines and sprinklers have been chewed off by animals, I have liens on my home from unpaid utilities, and Mario didn’t even know that his sub-tenant moved out of my home.

The cat urine probably soaked into the concrete.

My first thought is that the house needs to be gutted and rebuilt because that's the only way to get rid of the pervasive aroma of cat urine and ammonia.

Pet urine will seep thru the cracks in the flooring, and saturate the under layment.Ceramic tile, the grout gets soaked the urine seeps thru and saturates the under layment.Concrete the urine saturates into the cement and it's terrible.You will never win and damages may not appear for a period of time.
