Keep in mind, I also allow small pets, cats and dogs.

I read online that in some states if one charges a pet fee that doing so restricts what the security deposit can be used to address if there are damages beyond the amount of the pet fee. 

Don't forget to also search for "addendum" for those 'other' areas of special concern:  appliances, animals (pets), smoking, utilities, etc. 

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.

Hey @Drew Zoller,I had a similar situation with pet urine in my current live-in flip. 

Also decide on a pet / smoking / guest policy.

This can include your income requirements, minimum credit score for an approval, pets/no pets, etc.

You can also offer to add dishwasher, or even fenced in backyard (or portion of the backyard) if the tenant has a dog (and you allow pets).  

Pet urine?

The HOA states that only one pet is allowed per unit.
