The consulting firm IHS Global Insight reported that the Fort Pierce-Port St. Lucie area is among the most underpriced markets in the nation, with values only two-thirds of what they should be. Though foreclosure rates are high and unemployment remains a serious issue, some realtors say this could be a valuation bottom. Vincent Laviano, president of the Realtor Association of Martin County and owner of Better Homes and Gardens Real Estate Laviano & Associates in Stuart, Palm City and Port St. Lucie, said prospective buyers may look back at this period as the window of opportunity and regret not taking advantage.
