They said they scrubbed it away with a bleach solution and haven't seen a reoccurrence but wanted me to know about it.  

This won't ever change no matter what, so the solution for the landlord is a very good lease and as high a security deposit as you can get.As a new landlord you will go through the typical cycle: You will start with certain expectations that you believe your tenants will adhere to, those expectations will slowly over the years be eroded through repeated disappointments and lots of head shaking where you just can't believe the things you will experience, eventually you'll get to the point where the disappointments will end because you will have eliminated all sense of having any expectations, nothing will surprise you anymore so there will be no stress, the most absurd crazy stuff you will just take in stride with a simple mantra you will repeat as a landlord "They are tenants, there is a reason they are renters..."

So the solution is easy right?  

What was your solution?

Clayton Building Solutions.

As of right now they still want to make the drive, I was just trying to bring a easier solution. 

She might have a less expensive solution for you then calling a securities attorney for a deal this small. 

It's not a matter of claiming back tax, but a matter of having eyes-wide open when you set-up your ownership structure.Again, what works for us and what works for you, may not be the best solution for the OP.

I don't have a solution to that. 

I ended up calling Royal Legal Solutions (podcast guest #109 on asset protection).
