Insurance and maintenance will be high as it's commercial (extra maintenance, lighting, heat in the common areas that can't be charged back to individual tenants). 

Interior gutted down to studs, removed walls for open floor plan, replaced 90% of homes original plumbing and electric, added central air and heat, removed old oil burning system.

@Andrew MichaudDefinitely check the expenses as heat and electric look low for maine - especially if it’s off of oil which also your price may have doubled in past year.

A lot of the bones, boilers, water heats, plumbing, electrical was already in good condition so that was a huge plus!

The heat was very high recently and the air conditioner above unit had some issue and the water dipped from the pipe of that unit and damaged my unit.So I requested clarification to my property management company how they provided a quote without identifying the root cause, but haven't got any response yet.

We replaced a toilet and have repaired/replaced components of both heating units.

Can you make all electric with mini-splits or other individual heating systems?

Severely Under performing duplex for sale with all owner paid heat / single boiler.

This is the simplest method, but it also means your tenants are more likely to abuse the utilities by leaving windows open with the heat or A/C running, leaving lights on, ignoring the toilet that constantly flushes on its own, etc.3.

The house is newly renovated with central air and heat, all new appliances, and granite countertops.
