PPI’s monthly look at home values in 16 potential 2012 battleground states–our Battleground Home Values Index, May ’12– confirms values have bottomed, and are now showing price appreciation in the states that will decide the winner of the 2012 Presidential elections. This is welcome news for not only homeowners in battleground states, but for homeowners nationwide. With a clear bottom in values established, the “Big 3” of the housing crisis, Nevada, Arizona and Florida, have all seen prices move to the upside since the end of 2011, with Arizona experiencing a strong 4% move up.
