Here's the regional breakdown according to the press release:
Yearly growth for the broader national market expanded to 2.2% in July, 0.5 percentage points higher than June. Boosting growth at the national level, the West saw home prices roll up an impressive 6.2% over the previous year. The South and the Northeast also contributed to national price growth, with 1.8% and 1.6% yearly gains, respectively. While the Midwest has yet to post long term growth, the slight decline of 0.1% improved over last month’s yearly losses of 0.6%.
The report contained some interesting notes about the West region in particular which is the first region to see more broad-based increases in home prices beyond the lower-tier homes. That is, the West is the first region to begin to see increasing and broad demand for more expensive homes.
