Cathy, Some leases call for compensation to the leasing agent at the
renewal of an existing lease. More Common in Commercial and "High End"
Condo lease agreements. Your current lease will have the terms of renewal
and who is responsible for any commissions involved.
As "new " fee outside of your lease agreement this would be unusual. Contact the
Manager for an explaination . I f it can't be shown how this applies to you
