Housing prices? Yes, we’re still thinking about them. Thanks to a new dataset, we are able to continue our project of building home sale pricing dashboards for the 11-county metro area.

The trend of rising housing costs, especially since the onset of the COVID-19 pandemic, has been well established. Prices for new and older homes alike have been steadily increasing in many parts of the country. Last summer, we embarked on a journey to build interactive web applications visualizing historic housing prices by county in the metro area. You can find the collection here:

• Forsyth County
• Fulton County
• Cobb County
• Henry County
• Rockdale County
• Douglas County
• Fayette County

This new dashboard for Gwinnett County leverages a statewide dataset from ATTOM Data Solutions. This rich dataset contains record-level home sales which we have aggregated to the Census tract level.

The dashboard (built for desktop, not mobile screens) can be accessed here, and we have included a screenshot of the dashboard below. It features an expandable left-hand side panel with a toggle for the dashboard variable: total sales, median price per square foot, and median overall price. Sidebar sliders allow filtering for transaction time frame, construction vintage of the home, and city/region toggle:

Findings

Here are a few pertinent findings highlighted by the dashboard:

• From 2020 to 2024:
  • 75,835 homes sold countywide;
  • the overall median sales price countywide during this time period was $343,700, while the median price per square foot was roughly $147.
  • the median sale price per square foot rose nearly 58%.
• The peak price per square foot occurred in August 2023, with a countywide median of $184.
  • The countywide median price per SF decreased drastically in Q4 2022 and to a lesser extent in Q4 of 2023.
  • The most recent countywide price per SF, $183, is nearly back to this peak price seen nearly a year ago.
• Since just 2022:
  • Nearly 32,000 homes have sold countywide;
  • the overall median sales price was $390,000;
  • the median sale price per square foot was roughly $175 and has risen by almost 6%
  • this change has been slightly more pronounced in older homes, as this class of housing stock has risen by roughly 8% over that same time period.
• Homes sold in just the Lilburn and Lawrenceville sub-geographies (SW and central Census tracts) from 2020 to 2024 featured a median construction vintage of 1985.
  • The median price in these sub-geographies has been $170 / SF with a median size of just over 1,900 square feet.
  • Contrast these numbers to the Buford / Sugar Hill sub-geography, where the median price from 2022 onward has been $189 / SF with a slightly smaller footprint (about 1,860 square feet).
  • Meanwhile, the NE Gwinnett sub-geography has seen newer, larger homes sold over the same timeframe, with a median price of $175 / SF and a median home footprint of 2,236 square feet.

Happy data exploring, and we hope you’ve enjoyed this series of local housing dashboards around metro Atlanta!
