Standing dog urine will dissolve the glue and get into the underlayment.

The tenant had a dog and the dog must have had urinated in on every floors consistently.

We were happy with it but we noticed that the house was not clean - the blinds were dirty, the carpet was soiled and the house smelled like cat urine.

I have a situation/question I hope i can get some wisdom on to aid in somewhat of a hurtle in investing into longterm/larger deals... 

@Anje WalfoortI think the city fees are some of the biggest hurtles for developers.

Several months ago when my HVAC contractor showed up to take care of an issue at one of my rentals, he told me that the dog urine smell in the house was so strong he was afraid he might pass out.

Pet urine in a carpet will affect the pad and subfloor too, so that can become quite costly.

Smell of urine in a property usually equates to the smell of money.  

There is feces everywhere and urine to add the pleasant "new home" aroma.Anyone have experience getting SERIOUS PET SMELLS out of a house?

Go on the facts.White vinegar applied to animal urine, smoke etc will initially blow you away.
