Sales fell by almost 15% from November 2012, with Long Island, N.Y., one of the areas hardest hit by Hurricane Sandy at the start of the month, declining by 26%.
Still, Redfin noted each of the 19 markets it tracks had a year-over-year in home price, with Phoenix leading the way at 34%.
The percentage of listings selling within 14 days of their debut was 28.2%. California is the hot state, with six markets there leading the pace: San Jose, 59%; San Francisco, 49.5%; Ventura, 47.6%; Los Angeles, 43.1%; San Diego, 40; and the Inland Empire, 37.3%.
At the other end of the spectrum, only 4.1% of homes in Boston sold within two weeks of listing.
Previously, Seattle-based Redfin predicted the 2013 home buying season should start in early January as strong consumer demand, paired with low inventory, will keep prices rising in the spring.
