As of September 2026, the MLS records 6 closed sales in Castle Gate in Snellville, GA since 2024, the most recent in July 2026. Across Snellville as a whole, 434 homes closed in the last 12 months at a median of $355,000, 39 median days on market, with 101 homes for sale today. At that median and Gwinnett County's 2025 rate of 27.1 mills, annual property tax runs about $3,850.
Castle Gate sits inside Snellville, in Gwinnett County, and at the moment the current MLS snapshot does not surface a defined set of community amenities tied to the listings. That is not unusual for smaller or established subdivisions where amenities are not centrally recorded, but it does mean pricing here is being set almost entirely by the homes themselves rather than by a clubhouse, pool, or gate as a line-item feature.
For a buyer, that puts the weight of due diligence on the individual property: condition, lot, updates, and how a specific home compares to what else is active or has recently closed nearby. For a seller, it means the listing has to do the work of describing the home and its setting clearly, since there is no shorthand amenity package doing that job for you.

The 60-Second Overview
Castle Gate is a residential community in Snellville, Gwinnett County, where current MLS data does not identify a distinct amenity set for the neighborhood, putting the emphasis on individual home characteristics rather than shared community features.
Georgia MLS sales records identify 6 homes in Castle Gate that have changed hands since 2024, built between 1978 and 1986 (median 1984), with a median living area of about 1,424 sq ft and a typical 4-bedroom, 2-bath layout; 100% are single-family homes.

The Castle Gate buying strategy.
If we were buying in Castle Gate today, this is the order of operations we would run for our clients.
Underwrite the condition first. Price the roof, HVAC, and systems honestly before judging any list price; condition swings value here more than square footage alone.
Match the home to real comps. Recent sales of similar condition and lot, not the asking price, tell you what a home is worth.
Move deliberately, not desperately. Neither side has a decisive edge, so a well-prepared, fairly-priced offer wins without overpaying.
Line up financing and inspection early. A pre-approval and an inspection plan let you act fast and negotiate from evidence.
Keep an agent in your corner. The listing agent works for the seller; we represent you and prepare a hand-built valuation before any offer in Castle Gate.
What actually drives value in Castle Gate
Without a documented amenity package showing up in current listings, Castle Gate is best evaluated the way you would any Gwinnett County subdivision that competes on the fundamentals: home size, lot, condition, and proximity to the daily-use corridors around Snellville. Buyers should not assume a pool, clubhouse, or gated entry exists simply because of the name; verify any such feature directly rather than relying on branding.
That also means comparisons to other Snellville communities should be made property-by-property rather than amenity-to-amenity. A buyer weighing Castle Gate against a neighboring subdivision with a documented amenity set should factor that difference into value, and a seller here should lean on what the specific home offers since the community listing does not currently carry that marketing weight on its own.
The location and the amenities are priced into every listing in Castle Gate. The deal is won or lost on condition, the comps, and the renovation math.
