Fair housing-  due your research on accepting service animals, even if you say no pets. 

Can I legally charge them pet rent?

There is a product called OdorXit AQM which I used successfully in a unit which was very badly assaulted with pet urine. 

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 even eliminated pet fees unless you have more than 2 (i usually turn more than 2 pets down anyway). 

That once you begin painting and working outside the pets will need to be contained in the house during the work.

This is my 4 rental putting into service, I have never considered pets before and that new carpet and paddling that was just installed looks and smells great right now. 

That they had to keep away from anything flammable, themselves, their kids and pets? 

No pets are permitted on the premise without prior written consent of the Landlord.

@Joe Splitrock My interest rates on the loans I would be paying off are 8%.While I know this is not what you meant about the tax write off, you have hit on a bit of a pet peeve of mine.
