Along with a kiddy-pool sized litterbox in one corner of a room, cat urine and feces in the OTHER corner of the room on the carpet (newly installed by the seller when I bought), and a smell that made my eyes water walking in the front door.The lease has a clause for Tenant-Caused Damages resulting from tenant negligence.

If you get cat urine in the house, it can cost you 10x the pet fee to mitigate the odor.

When you posted your review, we assessed the unit to see if there was evidence of mold, urine or any other health hazard.

They often also require appraisals and additional hurtles.

Show up its a disaster of the human condition (  disabled kids smell of urine etc) how am I going to evict them.

If you use a urinal at a Cleveland Cavaliers game go ahead and place a business card on top of the urinal.Wear a name tag everywhere you goGet a name tag that says Realtor with your name underneath it.

You may be able to bypass some of those hurtles based on your country of origin/where you have friends and family but in most cases investing in the U.S. will be way easier and will yield a better ROI. 

(I've heard stories of ceramic tile grout lines that were so soaked in urine that the smell wouldn't come out.)Although ceramic tile looks nice, vinyl should be your go-to in a rental bathroom.

Furthermore, after having a dog live in the house for 3 years there is almost certainly animal urine that has soaked through the carpet into the subfloor.

The rental had ratty furniture, a record player prominently featured in the marketing but it had no speakers, missing basics items in the kitchen, lots of drunks in the concrete hallways that reverberated right into the bedroom at 2am, a strong odor of urine outside, and more.We have super hosts in this forum that have hundreds of 5-star reviews and are masters of the craft, but I look at their rentals and see they don't have any artwork on the walls, decor is basic, they do nothing to make the guest feel welcome, etc.
