IE pet fees and deposits or non-refundable anything.  

Anyway, it is a pet peeve of mine.Oh and i lived 30 min from my properties and never had a hard time getting there.

My moat is lower rent (I know the new apartments can compete there but with building costs I cannot see how...oh, and other moat is tiny yard for pets.

Between the pet damage and the lost rent $1000/mo), I lost money (vs normal) even after getting her to forfeit her security deposit ($1300) and settle out of court in a 3 month payment plan for like $1200.Call them or meet with them and have a conversation about their strategy going forward to pay on time.

Which kinds of pets did they have? 

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.

I'm thinking:  recent law updates, handling specific tenant issues, when to raise the rent,  service/companion animals, vs pets;    Specific ideas would be best.   

I was thinking of accessing the "damage" when she leaves and withholding the $400 non-refundable pet deposit?

You can purchase state specific, lawyer drawn-up documents (lease, application, pet lease, etc) right from Bigger Pockets at: https://get.biggerpockets.com/forms/index/I checked and the do have Ohio forms.

With the exception of protected classes of people or specific laws targeting specific areas (pets, family size, etc), a landlord can charge different tenants different amounts for any reason.
