Absolutely do not rent!
I vacated and received no monies from my deposit - rather a billing charging me for re-carpeting due to urine stains. I had no pets and assuredly had/have control over my bodily fluids.
I was advised a collection agency will ensue.
I see another tenant recently posted a similar situation so apparently my case isn't an isolated occurrence and quite likely a means for this business to generate income beyond rent.
Are you sure you want to live here? If so, you had better hope the prior tenant(s) didn't have pets.
