Usually, our leases are for 12 months and run Summer to Summer when vacancy times are the shortest, this also allows us to capture the highest rental rates which are in the summer. If we are attempting to lease a property in the off-season (winter for example), then we may create a 6 or 18-month lease which creates a summer lease expiration. Some Tenants have been “grandfathered in” with their old lease from another management company/Owner. New leases are written for up to 12 months.
