Hi and thanks for using justAnswer.com.
Electric resistance heating is the most inefficient, and therefore most expensive, way to heat anything. Currently there is a Fed rebate of $1500 for energy saving improvements. Any system you install will pay for itself compared to electric. And keep in mind Obama is hell bent on large price increases on energy to pay for his carbon tax. This will shorten the return on investment time. I would offer a price for the property as if it had no heating system at all.
