Minneapolis does require you hire Minneapolis licensed contractors that are expensive and can add 100's to 1000's to each repair bill for things like electrical, plumbing, heating, AC, siding, and roofs. 

I don't see any:lawn care or snow removal (which may mean snow removal from the roof as well), Trash Pickup90% of the duplex type properties in Maine would have 1 heating system meaning landlord pays (can be substantial depending on the property), electric could be per occupant but checkI assume you would also pay water sewer --  maybe $60 per monthA building like this is Waterville is probably a old converted single family even if it is all redone I would reconsider your repair and capex estimates I don't know local Waterville but double check the property taxes

@Marc Biviano We installed a 13.1 KWP / 48 panel system last July.We had a negative balance due to Eversource throughout the summer, but with our baseboard electric heat, we've burned through that. 

Wasn't really sure which category to put this under, but I've had two pretty heated discussions with my father about entering into real estate holding.

Preference is to Silicon valley where i live, but considering over heated market here, think investing nearby may not be possible for my budget (about $450K)However there are few areas like Richmond, Stockton/Tracy in this price point, but not much upsides there.

My tenants heat went out last night.

This is a long term buy and hold for me and I just had central AC installed so was looking for something that held some type of insulation value but was also concerned about hurricane protection as I don't want to be running around to all of my properties in the future putting up plywood.I wont be paying for heat but the bottom line is these windows will have to be replaced sooner or later. 

i would think finding a mentor, slightly out of the area may be a good move, so that you actually don't compete with each other but can actively and whole-heatedly bounce ideas off each other as well.

Heated toilet seats with bidet.

Also kicking around putting electric heat in the upper unit to eliminate the need to back charge for gas.
