Here are 5 charts showing the history of the most important aspects of single family home sales in Austin through March'08: number of sales each month, average prices each month, average number of days to sell homes, number of listings and price range vs. estimated number of days to sell homes (just for March'08). As you look at the 4 historical charts, note the seasonality of numbers of sales (twice as many homes sell in the summer as in January), slightly higher prices in summer, less time to sell in the summer, more listings in summer. Note also the seasonal patterns are holding so far in 2008.
