You can also compete on other things like included lawn care, pets allowed, stuff that tenants care about but also benefits you by allowing a better price.

She does not have approval for any pets, paid no pet deposit and certainly we could not approve a pit bull.    

I think its essential to protect the property especially if you dont allow pets.
