LAS VEGAS - MARCH 21: Prospective buyers look at a bank-owned house during a RE/MAX Central bus tour of foreclosed homes March 21, 2009 in Las Vegas, Nevada. RE/MAX Central of Las Vegas co-owner Ruth Ahlbrand said the Las Vegas area has been one of the top three worst foreclosure markets and one of the top three worst markets for slumping home prices in the United States since late 2007. Ahlbrand said the real estate group began giving tours for prospective buyers three times a week in February 2008, in an effort to clear inventory of foreclosed properties.
