We operate a vacation rental management firm and the % would be on RENTAL REVENUE, not taxes, cleaning fees, pet fees, etc.

Hi @Sam Liu it's fairly common to charge an additional monthly pet fee for MTRs to account for any additional wear and tear on furniture. 

Consider 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.
