Gwinnett County’s $457,000 median listing price hides a large amount of variation between the local markets inside the county.
Realtor.com’s historical data through July 2026 shows a wide spread in median asking prices across the city markets it tracks. Among markets with at least 100 homes listed in the same table, Norcross was at $352,450 while Suwanee was at $671,750 — a difference of more than $319,000.
Other July medians included Snellville at $408,116, Lawrenceville at $417,225, Lilburn at $446,675, Duluth at $471,000, Grayson at $477,350, Sugar Hill at $521,875, Dacula at $542,500, Peachtree Corners at $549,800 and Buford at $564,750.
Those numbers are asking-price medians, not closed-sale prices and not estimates of what every home in each place is worth. The distinction matters because the mix of homes listed in a given month can shift the median, especially in smaller markets.
Realtor.com also lists Berkeley Lake at a much higher $944,500 median, but only 16 homes were shown for sale in the same table. That small count is a good example of why a single median should be interpreted carefully rather than treated as a precise measure of an entire city.
The city labels also come from Realtor.com’s market dataset. They are useful for comparing the markets the site tracks, but they should not be assumed to match municipal boundaries parcel for parcel.
Why it matters
For prospective residents, a countywide median is only a starting point. The asking-price environment can look very different depending on which part of Gwinnett a buyer is considering. For homeowners and real-estate professionals, city-level medians can help show where the active listing mix is concentrated at higher or lower price points without claiming that one market is automatically “better” than another.
What happens next
The next monthly update will show whether these gaps persist or narrow as the mix of homes for sale changes.
