With the annual release of SalesTraq’s 2017 Las Vegas Price Appreciation map, every zip code within the urban Las Vegas valley posted positive price appreciation from the prior year.

In addition to a tight supply of resale homes on the market, the performance of the real estate market was boosted by an increase in population and employment.

Different portions of the valley experience varying degrees of supply and demand. Consistent with recent years, zip codes with overall lower housing values have tended to report the higher rates of appreciation in percentage terms.

Additionally, higher-end communities have tended to post lower rates of appreciation, but they remain closer to prior peak values experienced before the last economic downturn.

The zip codes with the highest home value include 89138, 89135, 89052, 89044, 89012, 89085, 89131, 89144, 89134 and 89141. These zip codes include areas in Summerlin and Henderson.
