The Real Estate Market is cyclical.  However that is no guarantee that one particular month is going to be better that another.  Often the contrarian approach works best.  The chart below shows volume over the typical calendar year and average sale price in that same year.

This chart illustrates average price paid drifts upward from January to May, takes a summer vacation and hits a plateau for the balance of the year.  Contrarians find that they actually benefit from an aggressive pricing strategy in what are seen as slower months due to lack of product for buyers during that slower time.  Multiple offers resulting in greater than fair market value prices are seen in January.
