Northampton's pricing is being set by a small, fast-moving pool. With a median of $858,500 and only 11 median days on market, the six closings behind this snapshot suggest homes here are not sitting long enough to build up the kind of price softening you'd see in a slower pocket of Cobb County. That pace is the headline, more than any single amenity or feature.
The price-per-square-foot median of $222.34 is a useful check against list price when a home's condition or floor plan differs from the last sale. In a market moving this quickly, buyers who wait on a full comp set risk losing the property, while sellers who price against stale data risk leaving days on market they don't need to give up.

🟡 Balanced market. 2.0 months of supply and 0% of the inventory already under contract put buyers and sellers on roughly even footing.Why it matters: months of supply is how long today's inventory would last at today's sales pace; under-contract share is the portion of homes for sale that already have a buyer.Momentum Research analysis of Georgia MLS records, as of September 20, 2026. Confidence: Medium (1 active and pending listings, 6 closed sales in 12 months).
🔴 Off the recent peak. The trailing-12-month median ($858K) is down 12.4% from the prior 12 months ($980K). With about 4 sales a year, a single closing can swing this number, so read the level and the decade, not one year's move.Momentum Research, record-level Georgia MLS closed sales, 12-month windows ending September 20.

The Northampton buying strategy.
If we were buying in Northampton 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 Northampton.
What the numbers are telling us
A median of 11 days on market, drawn from the most recent six closings, is a short window by most standards — it means well-prepared offers are getting accepted quickly and there is little room for a slow-walked decision. Buyers should expect to move on a showing schedule that matches the market's pace, not their own.
No community amenities are identified in current MLS listings for Northampton, so anything beyond the home itself — pools, clubhouses, trails — should be verified directly rather than assumed from the community name or general area reputation. The value proposition here reads as being about the home and its location within Marietta, not a packaged amenity set.
The location and the amenities are priced into every listing in Northampton. The deal is won or lost on condition, the comps, and the renovation math.

They are a framework for comparing communities, not a guarantee of future value and not advice on a specific home; unlike an automated value estimate they do not price your home, they grade the community on evidence you can inspect. Composite is the plain average of the 3 factors (7.0). Basis: Recent Direction -12.4% year-over-year; Liquidity & Demand 2.0 months of supply; Pricing Power 100.6% sale-to-list. Refreshed with each data update.
