Broward County's wealthiest residents have benefited considerably from the state's popular but controversial Save Our Homes law that caps property values used to set local tax bills.A South Florida Sun-Sentinel analysis of property records shows owners of palatial estates and waterfront mansions pay taxes on less than half of their home value. However, the owners of the most modest homes and condos are taxed on two-thirds of their home value.Former football star Dan Marino, auto dealer Rick Case and JM Family Enterprises founder Jim Moran are among the biggest beneficiaries. Others include Swap Shop owner Preston Henn, local real estate investor M. Austin Forman and former Philadelphia 76ers basketball team owner Harold Katz.
