They did have a dog that he mentioned yesterday because the kids wanted a dog (violation of original contract, didn't pay pet fee).  

They include leases, pet addendums, check in/out forms, etc.

Pets, too many occupants, not enough income, bad credit, picky criteria, too many things, etc. all come into play. 

House is in Florida.The 4 person applicant also has pets.

Maybe allow small dogs with pet deposits.

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.

Maybe people want years for the kids or pets, maybe they want their own laundry or garage, Or maybe SFR is just harder to compare. 

Does anyone have any experience allowing tenants to have snakes or geckos as pets? 

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 recently had tenants move out and discovered evidence that they hid a pet in violation of the no pet policy.
