Why the Tax Line on a SouthPark Listing Is Already Out of Date

In August, WSOC reported on a SouthPark luxury home that sold for close to $10 million after a 2024 listing. Through the county's 2019 and 2023 revaluations, its assessed value stayed around $5 million, and because Mecklenburg County lowered its tax rate over that decade, its annual tax bill actually went down.

That is an extreme case. The pattern behind it is common in SouthPark, though, and it affects anyone comparing homes here this fall. The annual tax figure on a listing reflects the value the county set as of January 1, 2023. Mecklenburg's next revaluation takes effect January 1, 2027, and early results show the largest increases in the price range where much of SouthPark sits.

The Number on the Listing Was Set on January 1, 2023

Mecklenburg County's goal is to assess every property at 100% of market value. It doesn't appraise each house one by one. As WSOC described it, the county splits Mecklenburg into more than 3,000 neighborhoods, studies sales in each one over a set period, and applies a resulting price per square foot to comparable homes.

Mass appraisal works best where homes are alike and sell often. It works least well at the top of the market, where homes are fewer and more varied. A Channel 9 analysis cited by WSOC found that in 2023, the most expensive 10% of homes in Mecklenburg County were assessed at about 71% of market value. The least expensive 10% were assessed at about 92%. Data from a University of Chicago project showed the same pattern, with the most undervalued homes for tax purposes concentrated in higher-value areas, including parts of South Charlotte.

So the tax line on a SouthPark listing combines two things. One is a value measured almost four years ago. The other is a valuation method that has tended to land below market at higher price points. The county assessor, Ken Joyner, explained the result to WSOC: "If your high-end areas are valued at a different level than your low-end, you're going to have those discrepancies."

This Revaluation Is Moving Fastest at SouthPark Price Points

On September 1, 2026, the county's Office of Tax Administration gave commissioners an early look at the 2027 revaluation. After an initial review of 428,506 residential and commercial parcels, the median residential increase was about 15%. The median commercial increase was about 30%. Staff are doing more reviews through the end of 2026, so these figures are preliminary.

On its own, 15% sounds mild. In 2023 the median residential increase was 60%, and the county now revalues every four years partly to avoid swings that large. The more important detail is in The Charlotte Ledger's report on the briefing. Unlike 2023, the bigger increases this time are at the upper end of the market, especially homes priced at $2 million or more. The Ledger's explanation is that most sales since 2023 have been luxury homes, because higher mortgage rates on top of pandemic-era price gains have kept many lower-priced buyers out of the market.

That connects back to the 2023 snapshot. Mass appraisal relies on recent sales. Since the last revaluation, those sales have been concentrated at the high end, which is the same tier the 2023 numbers undervalued the most. Of every price range in the county, the upper tier has the most new evidence for the county to work from.

Why a Revaluation Percentage Is Not a Tax Bill Percentage

Your tax bill is your assessed value times the rate, and the rate is not fixed. Under North Carolina law, a county or city that has just completed a reappraisal must include a revenue-neutral rate in its budget for comparison. That is the rate that would bring in the same revenue as before the revaluation, adjusted for normal growth. G.S. 159-11(e) sets the requirement, and the county's revaluation page says rates are adjusted to keep the process revenue-neutral unless elected officials choose otherwise.

Here is how the 2023 revaluation played out:

All rates are per $100 of assessed value. County commissioners set the FY2024 rate 1.60 cents above revenue-neutral. Charlotte adopted exactly the neutral rate. Both rates have gone up since. Charlotte's FY2027 budget, which took effect July 1, 2026, included a 1.89-cent increase for public safety, and the county kept its rate at 49.27 cents. Inside city limits, including SouthPark, the combined county and city rate is now 78.57 cents per $100.

A revenue-neutral rate is calculated from the whole tax base, so it doesn't hold every individual bill flat. Charlotte's FY2024 budget put the break-even point at 33.7%. A home whose value grew by exactly that much in the 2023 revaluation saw no change in its city property tax. The median Charlotte home grew 63.3%, from $214,100 to $349,700, and its city tax bill rose 22.2%, from $745.28 to $910.62, even though the city adopted the revenue-neutral rate. A home that grew more than the break-even point paid more. A home that grew less paid less.

What the Relative Math Means at the Top of the Market

WSOC's examples from 2023 show how this works. A home on Queens Road went from $1.6 million to $2.8 million in assessed value, and its tax bill rose about $800. A home in west Charlotte went from $69,000 to $237,000, more than triple, and its bill rose about $1,000. The size of each increase depended on how each home's value moved relative to everything else in the base.

The 2027 numbers line up differently. Early results put the residential median at 15% and the commercial median at 30%, so commercial property is moving faster than homes overall. Within residential, though, the county says the top tier is moving the most. For a SouthPark buyer, that means the relevant comparison is how a home's new value moves against the countywide base. A 15% median says little about any one house, and homes over $2 million are where the gap between the old snapshot and the new value looks widest.

Two things are still unknown. Final values won't be out until early 2027, and rates won't be set until spring. The Ledger's reminder applies here: a higher assessed value doesn't automatically mean a higher tax bill. The opposite holds too. A home that already pays a low effective rate on a 2023 value may not keep that rate.

For scale, current published rates applied to a $2 million assessed value inside Charlotte come to about $15,714 a year in county and city property tax. If a listing's 2023 assessment sits well below what the home sells for now, the tax line is showing what the current owner pays on an older value. Next year's figure is still undetermined.

The Calendar Between Now and the First New Bill

1. January 5, 2027. This is the deadline to pay current-year real estate taxes without interest, which starts January 6. That bill uses existing values and FY2027 rates.
2. Early 2027. The county mails new value notices and posts values online. According to the county's revaluation FAQ, owners can request an informal review within 30 days of the date on the notice, or file a formal appeal with the Board of Equalization and Review. The county's appeals page says revaluation appeals can't be filed until notices are mailed.
3. Spring 2027. County, city and town officials set tax rates, and those rates apply to the new assessed values. Each budget must show the revenue-neutral rate for comparison.

In the meantime, the county encourages owners to check their property record card for errors in recorded details. Its example is a wrong bathroom count, which could affect value. Buyers can look up any address on the county's public property portal, which shows values, building details, land use and sales history. Comparing the 2023 assessed value with a home's asking price shows how much that home's value has moved since the last snapshot.

Two Questions Specific to SouthPark

Does the SouthPark district tax apply to a single-family house? No. Charlotte's Municipal Service District 6 for SouthPark carries a rate of 3.81 cents per $100 in FY2027. It applies to commercial and multifamily properties, not single-family homes, according to the Greater Charlotte Apartment Association's summary from when City Council approved the district.

Are there preliminary figures for SouthPark specifically? The county has released only countywide medians so far. Individual values arrive with the notices in early 2027. Through November, county staff are briefing town councils and Charlotte leaders at public meetings, according to WFAE.
