When the renter moved out, I found that the carpets were ruined due to urine stains.

Not saying you cannot, just that there may be an additional hurtle vs a backyard adu.

You can also buy some predator urine spray online and spray that everywhere.Do some searches online for more ideas.Oh, and if you see the guy in the picture below, your screwed...Hope that helps.

I love the smell of pet urine when I buy.

Two months later PM installed a new fan. 5) PM: "The guest sent a letter and said the house smells like dog urine and they want a refund."

I would love to get rid of any pet urine quickly.

I am not saying you should or shouldn't; if you decide this is a hurtle you're willing to overcome, then I hope you slay it.

I spent $550 with Stanley Steamer to deep clean and deodorize the carpets and deep clean all of the tile surfaces (mostly the kitchen and back hall area that smelled horribly of dog urine). 

He did not leave a new address.The next morning I walked into a dirty house with urine stench.

I learned what an OZONE machine can do, that you can seal a floor to get rid of cat urine smell by simply painting it, and that IT's ALL WORTH IT!!!!
