Phoenix region bargain hunters drove sales of existing single-family houses above year-ago levels for the seventh consecutive month in January. Foreclosure properties climbed to 66% of all resales, helping to push the median sale price down sharply to its lowest point since spring 2002, a real estate information service reported. A total of 5,423 new and resale homes closed escrow in the combined Maricopa-Pinal counties metropolitan area in January, down 19.8% from December but up 2.7% from a year ago according to MDA DataQuick. The San Diego-based firm tracks real estate trends nationally via public property records. Last month's nearly 52% annual increase in resales of single-family detached houses was just enough to offset year-over-year sales declines for resale condos and newly constructed homes, which posted decreases of 27% and 60%, respectively. New home sales in January 2009 were the lowest for any month in more than 11 years. The median price paid for all new and resale homes sold in the Phoenix area in January was $141,480 - the lowest since it was $141,430 in May 2002. Last month's median fell 8.1% from $154,000 in December and fell 37.1% from $225,000 a year earlier. January's median was 46.4% lower than the peak $264,100 median in June 2006. Another price gauge analysts watch has fallen more sharply: The median paid per square foot for resale houses fell to $72 in January, down 47.6% from a year ago and down 57.9% from a peak $171 in June 2006.
