It's a gas heater and currently, gas is pretty economical. If you'd like to take a look at this, send me your contact info at Sharon.Sapp@Century21.com and I'd be glad to set up an appointment. It's a large home (3620 sq feet) and it's in good enough shape to accept FHA financing. The roof was installed in 2009, it comes with 4 window air conditioners, the heating system is only 2 years old and even has a radon remediation system. I see no red flags and if is the type of home you like, you should definitely make an appointment to see it.
