This document summarizes the condo and townhouse market in Princeton, NJ in 2009. It provides data on inventory levels, absorption rates, average sale prices, and number of sales compared to previous years. The absorption rate, which is the number of months it would take to sell all current listings at the current sales rate, is a key indicator of market health. Absorption rates above 6 months indicate a slowing market with potential for price depreciation. Data on current absorption rates is given for both Princeton Borough and Township.
