Existing Home Sales fell 3.7% last month, lower than expectations by 210,000 transactions.  The inventory of available homes for sale dropped 6.4% last month and is at the lowest levels in history–in history.  The short supply of homes for sale continues to drive prices up: the median home price of $228,400 is an increase of 7.7% from this time last year.  Another measure of the historical price of homes, the FHFA (the parent entity of Fannie & Freddie) Home Price Index, shows a 5.7% increase from a year ago.
