Phoenix Home Prices keep going down...FAST!

Phoenix is faring worse than most cities according to the Standard & Poor's 20 City Housing Index.

NEW YORK (AP) _ A closely watched index shows Valley home prices tumbling by the sharpest annual rate ever in July.

The newly released Standard & Poor's/Case-Shiller 20-city housing index showed a record drop of 16.3 percent in July from the year-ago period - the largest drop since its inception in 2000. The 10-city index plunged 17.5 percent, its biggest decline in its 21-year history.

Home values in all 20 cities fell year-over-year, with Phoenix faring worse than most cities. Prices Valleywide plummeted more than 29 percent in July from one year ago.

The only metro area doing worse than Phoenix is Las Vegas, where prices are plunging at nearly 30 percent.

However, the pace of declines has slowed over the last three months, but there is still no sign of a bottom, one of the index creators said.
