The economy continues to expand, in spite of hurricanes, high energy costs, and Fed Funds rate increases.  The weeks’s crowded raft of economic reports was kicked off by housing.  The reports were mixed, but generally point to a slight cooling.  The National Association of Realtors reported Monday that sales of existing homes fell 2.7% in October to a seasonally adjusted annual rate of 7.09 million.  Houses stay on the market longer as the inventory of homes on the market rose to a 4.9 months' supply in October, from September's 4.6 months' supply.  Meanwhile, housing affordability dropped as the median sales price rose 16.6% on an annual basis to $218,000.  That was the biggest jump in 26 years.
