Homes in Bethlehem
Half the homes in Bethlehem were built before 1956 (Census ACS median), so the typical house is about 70 years old. 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 50.7% of occupied homes, roughly 16,000 households. The median home value is $236,500, and median household income is $66,443. We use both figures to adjust labor and pricing for this page.
