What the numbers mean in Knollwood CDP

Housing cost measured against local earnings.

A household earning the Knollwood CDP median would spend about 15.6% of gross income on the median rent. The 30% mark is the federal threshold for cost burden, so anything above it signals a stretched rental market. The median home costs 2.8× the median household income; nationally that ratio sits near 4.5×. Poverty affects 8.8% of residents and 76.8% of households own their home.
