Thanks Dmitriy I appreciate your insight and will definitely do my due diligence on whether i am dealing with the concern of an "active business" Thanks again 

Please understand too that we have no issue with a service dog or our tenants having one, we were just concerned that they would have every intention of training this dog, but then grow slack on its training and ending up with just a pet, and for free, no less, in our home and causing potential damage. 

Very dangerous. 

I don't know if I'm making sense, but should I be concerned that my realtor is getting sidetracked with outside, sweetheart deals that she's trying to sell to the out of towner...? 

The number 1 thing we should be concerned about is stability.

@Ashley Wolfe in my market I’m not concerned with bookings more than 8 weeks out.

Rent control is a dangerous trend these days, and my State is toying with this outdated idea as well.

Perhaps if it was called a "move in fee", or something along that line, it would be okay though.My concern would be there would be less motivation for the tenant to keep the place damage-free, or pay the last month's rent, because they'd know they weren't getting any money back anyway. 

I would be concerned if they are legit.

If there's a lot of lawsuits government regulators will be concerned.
