Where Atlanta Suburb Home Prices Are Rising Fastest (2026)

Milton's 30004 ZIP code has posted the steepest home-price gain among metro Atlanta's top suburbs since early 2023, with its median sale price climbing 24.3% to $845,000, according to property records tracked in NeighborScore's database. Alpharetta's 30009 ZIP follows closely at 20.5% growth, while Roswell, Peachtree City, and Marietta round out a group of six suburb ZIP codes where price appreciation has consistently outpaced days-on-market changes. None of these price gains are reflected in a ZIP's NeighborScore composite index, which scores safety and schools only — affordability is tracked separately as context.

Which Atlanta Suburb ZIP Codes Have Gained the Most Since 2023?

Comparing median home prices from the earliest available month in NeighborScore's property data (early 2023) to the most recent month on record (spring 2026) shows a clear order of appreciation across six well-known Atlanta-metro suburb ZIPs. Every ZIP below carries a NeighborScore composite index above 70, meaning each is already rated Good or better on safety and schools before affordability is even considered.

1. Milton 30004 — median price up 24.3% ($679,570 to $845,000); scores 88/100 overall (crime 95, schools 81).
2. Alpharetta 30009 — median price up 20.5% ($680,440 to $820,000); scores 80/100 overall (crime 80, schools 79).
3. Roswell 30075 — median price up 14.9% ($633,324 to $727,500); scores 87/100 overall (crime 95, schools 78).
4. Alpharetta 30005 — median price up 13.0% ($694,662 to $785,000); scores 83/100 overall (crime 80, schools 87).
5. Peachtree City 30269 — median price up 11.6% ($527,614 to $588,950); scores 89/100 overall (crime 95, schools 83).
6. Marietta 30068 — median price up 11.2% ($631,049 to $701,500); scores 71/100 overall (crime 65, schools 78).

The pattern is not random. The three fastest-rising ZIPs — Milton, Alpharetta 30009, and Roswell — sit in Fulton County's northern suburbs, an area that has absorbed a wave of corporate relocations and tech-sector job growth over the past several years. Marietta's 30068, in Cobb County, still gained over 11% but started from a lower crime score, illustrating that price appreciation and NeighborScore's safety-and-schools rating do not always move in lockstep.

How Is the NeighborScore Composite Calculated for These ZIPs?

NeighborScore's composite index blends only two components: overall_score = crime_score x 0.53 + school_score x 0.47. Safety and school quality are the entire score; a separate affordability metric, value_score, is tracked and displayed but carries zero weight in the composite. That distinction matters in this suburb set, because the ZIPs with the fastest price growth are not the cheapest ones — they are the ones where crime scores already sit at or near 95 out of 100, the ceiling of NeighborScore's crime tier for this metro. Milton, Roswell, and Peachtree City all post a 95 crime score, while Marietta's 30068 trails at 65, reflecting a higher relative crime rate versus its county baseline.

School scores separate the group further. Alpharetta's 30005 posts the highest school score in this set at 87, edging out Peachtree City's 83 and Milton's 81. Buyers chasing both price appreciation and top-tier schools have historically gravitated toward exactly these ZIPs, which helps explain why demand — and price growth — has concentrated there rather than spreading evenly across the metro.

Where Do Homes Sell Fastest, and How Affordable Are They?

Days on market tells a related but separate story from price growth. Roswell's 30075 and Alpharetta's 30005 both move fastest, with homes averaging 25 days on market, while Peachtree City's 30269 takes the longest at 50 days despite being the highest-scoring ZIP overall. That gap is a reminder that a strong NeighborScore composite does not guarantee a fast sale — market depth, inventory, and price point all factor into how quickly a listing clears.

Affordability, tracked separately as value_score, runs in the opposite direction of price growth across this group. Milton's 30004 — the fastest riser — carries the lowest value_score of the six at 23, meaning it is the least affordable relative to Georgia's statewide median home value. Peachtree City's 30269, by contrast, holds the highest value_score at 29, consistent with its lower absolute price point even after an 11.6% gain. None of this affordability context changes a ZIP's overall_score; it is presented on NeighborScore profile pages purely as a companion metric, not a grade. Statewide price data from the US Census Bureau shows Georgia's median home value has climbed steadily over the same period, a backdrop against which these six suburb ZIPs are outperforming.

The broader trend lines up with national tracking from Zillow Research, which has documented Atlanta's outer suburbs and exurbs closing the price gap with the metro core faster than in most other major US markets. For buyers comparing options, that means a suburb ZIP's price trajectory is now as important a data point as its current price, and NeighborScore's profile pages for each of these ZIPs break down that trajectory alongside crime, school, and affordability data.

Bottom Line

Milton's 30004 and Alpharetta's 30009 have appreciated fastest among metro Atlanta's top-scoring suburb ZIPs since early 2023, both gaining more than 20% in median price while holding strong NeighborScore composites in the 80s. Roswell, Alpharetta's 30005, Peachtree City, and Marietta's 30068 all posted solid double-digit gains as well, but the fastest-rising ZIPs are also the least affordable by value_score, confirming that in this market, price growth and affordability are moving in opposite directions.
