Rapidly Rising Home Prices In The West: Another Housing Bubble On Tap?

Home prices continued rising in the West, with Las Vegas leading the pack with a 29.10 percent gain year-over-year although average home price in Las Vegas, Nevada remains 46 percent than its peak in February of 2006.

California also showed double-digit year-over-year growth for home prices with San Francisco at 25.70 percent, Los Angeles at 21.80 percent and San Diego posting 20.90 percent growth in home prices year-over-year.

Rapidly increasing home prices in the West are largely due to demand exceeding supply, but buyers may be sitting on the sidelines due to concerns over another housing bubble in the making.

Buyers in this scenario are aware of increasing home prices, but aren’t buying now to avoid higher prices later. Instead they are waiting to see what happens with current home prices and housing market conditions in the longer term.

Chicago, Illinois posted its highest year-over-year growth rate since 2005 while Cleveland, Ohio posted a growth rate of 5.00 percent for September as compared to a month-to-month growth rate of 3.70 percent.

This was the second lowest month-to-month growth rate for home prices, with New York City posting a month-to-month home price growth rate of 4.00 percent from August to September.

FHFA Reports Slight Gain In Home Prices

The Federal Housing Finance Agency reported stronger gains in home prices for properties financed with mortgages owned or guaranteed by Fannie Mae or Freddie Mac. In September, home prices reported by FHFA rose by 0.30 percent as compared to August’s growth rate of 0.40 percent. 

On a year-over-year basis, FHFA reported a gain of 8.40 percent between the third quarter of 2012 and the third quarter of 2013. Adjusted for inflation, home prices as reported by FHFA have risen approximately 7.20 percent. FHFA noted that home prices are growing at a rate far above the rate of 1.20 percent reported for other “goods and services.”

Lower numbers of foreclosed homes are seen as a boost for home prices in general; as mortgage lenders tend to offer foreclosed homes for sale at low prices in order to reduce inventories of real estate owned.
