Regular maintenance options for 80-unit

[Dave Rav]

Hey group!  Wanted to ask about ideas for keeping up with regular maintenance on an 80-unit apartment building in SC.  We are currently vetting the property for purchase.  Accurately capturing the maintenance expense is of importance.

Property is actually comprised of 3 buildings next to each other (centrally located).  Age is 1970, but about 35% of the units have been renovated within last 2 years.  This includes new HVAC, some plumbing, kitchen upgrades, and cosmetics.  I do not believe any roofs have been replaced.  

Primary questions are:  Employ a small team of gen maintenance handymen?  Employ a maintenance sup and hire a few part-time folks to assist?  Other ideas?  Any feedback is greatly appreciated.

Thanks!
