Bubbles Bloom Anew in Desert as Buyers Wager on Las Vegas

A five-bedroom house in Las Vegas sold in mid-July for $499,000, double the price it went for three months ago. In Phoenix, a similar house sold this month for $600,000, gaining $273,000 since March.

Bubbles are inflating in Nevada and Arizona even as housing in the rest of the country recovers at a more sustainable pace. Gains in the two desert cities are the biggest since the height of the real estate boom, just before their plunge to the bottom of the national housing collapse. This year, Las Vegas and Phoenix have topped the nation in price increases, according to the S&P/Case-Shiller property-value index.
