Existing home sales were down in September and mortgage rates are rising. Data hints that the housing recovery is slowing or could be ending. The next S&P/Case-Shiller Home Price report due Tuesday October 29th should tell the story. After solid year-over-year gains of 12% or more in prices with home prices rising in all 20 cities, we could see far smaller price gains and even a decline in some cities. The report will be posted here and on www.spdji.com on Tuesday morning.
