Asking prices up in 86 of 100 largest markets

Asking prices of homes listed for sale on real estate portal Trulia.com in January were up from a year ago in 86 of the 100 largest U.S. metros, according to a monthly report released today.

The report, which covers roughly 4.5 million for-sale and for-rent properties listed on Trulia through Jan. 31, showed asking prices up 5.9 percent from a year ago, and growing by a seasonally adjusted 0.9 percent from December to January -- the biggest month-over-month gain since March 2012.

In some markets, the strong growth in asking prices doesn't necessarily indicate that worries are over, said Jed  Kolko, Trulia's chief economist.

"In  many local markets today, dramatic price gains can mask serious red   flags," Kolko said in a blog post. "Strong job growth, low vacancy  rate,  and low foreclosure inventory -- not huge price gains -- are  signs of a  healthy housing market."

Trulia identified San Francisco, San Jose, Seattle, Denver and Salt Lake city as "booming" markets with strong fundamentals.

"Rebounding" markets  like Phoenix (where asking prices were up 24.8 percent from a year ago), Las Vegas (up 16.8 percent), Riverside-San Bernardino (up 14 percent) and Detroit (up 14.2 percent) remain vulnerable to factors like slow job growth, high vacancies, or future foreclosures, the report said.

January marked the first time since last spring that asking rents posted a smaller year-over-year increase (4.1 percent) than asking price. The report noted that construction of new multi-unit rental properties has helped grow rental inventories in some markets.

"Rent gains are slowing down because of more supply, not less demand," Kolko said.
