Property revaluation letters have gone out to single-family homeowners in Mecklenburg County this month.
The deadline for the first step in an appeals process is 30 days from the date of the notice.
Mecklenburg County isn't the only one conducting property revaluations around Lake Norman.
Residents of Lincoln and Iredell counties are getting their notification of new appraisals as well, and Catawba County residents received notifications in November 2010.
The results of any appeals from the Catawba notifications are scheduled to be mailed this month.
