Maintenance Calls - Memphis 22 Unit

[Silenceux Francois]

I recently purchased a 22 unit in Memphis and transaction from the original in month 3 due to high management fee and unconventional way of managing i.e not running background checks, not assessing late fees, and no proper bookkeeping process but the ground were well maintained and maintenance calls were low/cost. Since transitioning to this new management company they automated the process of collecting rent, streamlining the process of bookkeeping but the ground is poorly maintained and an uptick of maintenance calls. 

Looking for recommendations on ways I could reduce maintenance calls and pricing. Do I hire another company to complete my maintenance calls moving forward?
