//ascending
homes.sort(function(a,b) { return parseFloat(a.price) - parseFloat(b.price) } );

//swap a.price and b.price to sort descending:
//homes.sort(function(a,b) { return parseFloat(b.price) - parseFloat(a.price) } );

//apparently this can be used for strings
//   if ( a.region < b.region )
//        return -1;
//   if ( a.region > b.region )
//      return 1;
//   return 0;
