Hi Gavin, I think the question becomes how much time do you inevitably spend on maintenance and what part is it? Is it coordinating budget approvals with owners? Finding vendors? Is it the scheduling and follow up? There are so many pieces of the maintenance puzzle that can affect its efficiency.
If you're not opposed to outsourcing, companies like mine offer lower cost alternatives to hiring a full-time employee and allow the cost of managing the maintenance to scale equivalently to your growth. We help solve the issue of finding a contractor, and tracking a work order through completion but if your problems like outside that you may look to hire internally
If you're looking for someone in the office to handle maintenance 9-5 you better make sure there is a 9-5 amount of work or else they start becoming jack of all trade employees which you inevitably will need to hire another coordinator down the line because their responsibilities will become muddled into the rest of the work flow.
