Do you know where your neighborhood stands?
Check The Charlotte Observer's comparison of recent home sale prices in 2006 and 2007 to tax values with an interactive map here.
The map above shows Merry Oaks. Red dots indicate home sales that were more than 50% higher than existing property tax values. Orange dots indicate sales that were 30% to 50% higher. Green dots indicate sales 10% to 30% higher.
