Houses that old often still have duct runs sized for an old coal or oil furnace and 60- or 100-amp electrical panels. Both can add cost when new equipment goes in. Owners live in 35.9% of occupied homes, roughly 12,000 households. The median home value is $122,500, and median household income is $47,102.
