Property Manager Extending Lease Month to Month without my permission

[Johnny Drago]

I had a property manager extend a lease on a unit M-to-M after the lease expired May 31. Unit became available middle of August after they moved out but wasn't ready to be rented out until the end of August. Now it's the first week of September and unit is sitting vacant. My question is wouldn't it have been more prudent to decline the M-to-M option and end the lease so that the property could be marketed during a prime rental month like June? I'm pretty annoyed by it and am venting.
