Heating - oil, gas or electric?

worcester is neighborhood by neighborhood and street by street, i have clients who paid $370k for a 3 decker and get $4300 /mo in rent with lots of choices and others who paid $250k and have $3050 a month all section 8 and may need to upgrade heating systems. 

Keeping the heating and cooling bills low is a win-win.

You will also increase your electrical bill for the pump (around $50 a month) and water bill for refill during summer.If you have a heating system, the cost will also be higher.You will need a self closing gate to access the pool and/or the unit next to the pool will need alarms on the doors/windows that can access the pool directly.

Other than the obvious, heat and air, plumbing, electrical, roof , etc and the rental history. 

Problem with this property is the Landlord pays all the utilities (heat, hot water, electric). 

Its not uncommon to provide heat and request for the tenant to provide cooling, but your home may sit on the market.

Heat breaks-- you're paying.   

I do not know much about the efficiency of these two different types of heating.

My upstairs unit heat is working great, except in one room (middle bedroom).No heat was coming out of it when I got the property, but my heating guy flushed the system, bled the radiators, replaced the water tank for the furnace, and all was well.
