According to the trend map (left) provided by the county’s Department of Finance, the area hit hardest by the assessment rise was the southwestern-most part of the county, from Columbia Pike to the border with Alexandria (area 10).
The average assessment for this area rose 11 percent, from $362,527 to $402,404. Homes in this area were the least valuable on average in the county last year and, despite the $40,000 jump, are the least valuable this year. If the tax rate remains at around one dollar per $100 of assessed value, the owners of houses in this area will pay about $400 more on average this year than last year.
