And in New Hampshire where it gets very cold in winter usually the landlord pays for heat and we are responsible to make sure all tenants have heat at all times.

Heating/Cooling - having central air or mini split system versus nothing/window units and electric baseboards can definitely sway your price.

Inform the tenant of your reasons and by at least starting the process, it puts the heat on her to officially move out. 

Currently heating and hot water cost to owner is $20K +.

A couple of other items like the cracked walkway & non operating heat may give you problems at inspection. 

Floor, ceiling heating, hvac? 

Best case scenario, everything is split out (ex. water, electricity, heating and etc.)

I don't foresee any big bubble but there are some indications that the heated pace of appreciation in some markets is starting to cool. 

Where I have rentals they will condemn a property for not having heat, water, electric.
