``A second wave of falling home prices is battering some cities that had escaped the worst of the housing market bust. Prices in Seattle, Charlotte, N.C., and Portland, Ore., have hit their lowest points since peaking in 2006 and 2007. Denver and Minneapolis are nearing new lows. High unemployment and rising foreclosures are taking a toll even on markets that never overheated during the boom years.''
