The sellers recently installed new forced air heat in all the units and the electrical service has been upgraded.

What kind of heating/cooling bills are you tenants looking at?

Age of roof, electrical, plumbing, heating, sewer?

It's a privilege one earns from hard work, tenacity and bit of luck.Simple choice: If you can't stand the heat, get out of the kitchen.P.S.

One of my concerns was the heating oil currently in the tank.

I.e- WSG (in coeur d alene), baseboard heat, Management fees.  

Owner pays water/trash/sewer & natural gas for water and heat.

James..Mechanicals, heating, cooling, septic or sewer, water source and piping, electrical and upgrades and roofing for a few.

Even making 5,000-7,000 on a low or no money down can take away some of the heat in a rental market.
