5.Do you have any pets?

We have what I would consider a decent listing with 21 pictures, detailed information, and we allow pets. 

If you keep your grass mowed, wet spots under control, they need to deal with the pet.

Think of all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

No extra rent or pet deposit can be charged. 

The property she lives in herself is in complete disarray and quite literally falling down around her, she is also a hoarder with pets so the place is a disaster and needs to almost be rebuilt from scratch.

I could offer her to bring the other cat as well and then be able to charge a pet fee and a deposit? 

I know many charge a pet fee + pet rent, but often that does not always cover the damages that could be caused by an animal.

My question is, since service animals are not considered pets according to American Disability Act, do applicants have to provide some sort of written proof that these animals are legally considered service animals?
