August 2025 to August 2026.
The three-August record
Alpharetta's Zillow Home Value Index was $724,528 in August 2024, $718,009 in August 2025, and $716,629 in August 2026. The latest 12-month change was -0.2%, and the two-year change was -1.1%.
The August 2025-to-2026 movement is close to flat. That is a reason to examine the actual comparable set, not to declare every property unchanged.
What the model measures
Zillow describes ZHVI as a seasonally adjusted, smoothed estimate of the typical home value in the 35th to 65th percentile range. It is not a median closed sale price, appraisal, listing-price series, investment return, or property valuation.
This study analyzes three reported city month-end observations. It does not isolate a neighborhood, waterfront, Lake Lanier, luxury segment, property type, or seller concession.
The reported value is a citywide model rather than a transaction-level sale series. Its usefulness is in setting context and prompting a current review, not in replacing the evidence needed for a specific home.
The practical next question
For a purchase, compare the specific homes, terms, property form, maintenance obligations and current alternatives that meet the actual need. For a sale, use a dated, property-specific competitive review rather than applying a broad index change to a prior price.
Ashley Smith can use the city context as an opening briefing, then move to the documents and current evidence that support a specific decision.
The report's period and scope matter as much as its number. Alpharetta is used here as a broad public reporting area. A smaller area, a particular property form, and an individual home can follow a different path.
A dated city indicator has value when it improves the questions asked. It should never replace a current review of the particular home, its competition and the evidence supporting its use.

How we calculated it
Filter Zillow's all-homes, seasonally adjusted city ZHVI file to the exact Georgia city.
Use the three reported August month-end values.
Calculate percent change as (later minus earlier) divided by earlier, rounded to one decimal.
- 2025 to 2026 ZHVI change: (716628.5168465282 - 718008.613113351) / 718008.613113351 × 100 = -0.2%
- 2024 to 2026 ZHVI change: (716628.5168465282 - 724527.6958464514) / 724527.6958464514 × 100 = -1.1%
What this can and cannot tell us
- Broad city modeled-value context only. It does not establish a neighborhood, Lake Lanier, waterfront, luxury-segment, MLS, or property-specific result.

Questions behind the numbers
Is ZHVI Alpharetta's median sale price?
No. ZHVI is Zillow's modeled typical-value estimate, not a median closed sale price.
Can this value a specific home?
No. A property review needs current comparables, condition, location, documents and terms.
Does this measure Lake Lanier or luxury property?
No. It is broad city context and does not isolate waterfront, luxury or neighborhood segments.
