I inherited the land and home so I have little cost basis.I have an offer from the state to buy the land for conservation purposes for $220k, but I'd have to demolish/remove the house and 3 large garages, several small sheds in disrepair, remove septic system, well, foundation of house etc.

Hood systems/fire suppression also very costly.You mentioned long term tenants for all units, but what are current and historic sales for commercial spaces?  

HVAC systems don't last more than about 10 years in salt air.

@Sheldon Peart  landlords will tell you the system is stacked in favour of the tenant. 

.- Using MassSave, upgrading the HVAC system to combi-boiler for main unit and mini-splits for rental unit.

This asset is located proximate to a major hospital system as well as a large university.

You must either spend capital for your marketing budget and have systems in place to take the calls or you have to invest a lot of time into chasing down leads (like driving for $).In my mind, and in this competitive sellers market we find ourselves, it seems much easier and less expensive to get your RE license and market for sellers leads to get legal commissions.

I'll definitely archive all of the great information.

So far this year, it's covered:Porter services for bulky trash removal for the 108 units.Paying off the loan that was used to replace all the vinyl siding with LP Smartside on all the units and paint them.Maintenance and repairs on all the external fire alarm system stuff.Regular landscaping.Tree removal after the big freeze.Regular powerwashing.Weekly litter pick up services.Pool services.And that's what I can think of off the top of my head. 

If there is potential damage to the electrical system, there is reason to shut off the power if it is not already off.
