The three-August record
Roswell's Zillow Home Value Index was $644,232 in August 2024, $645,038 in August 2025, and $653,146 in August 2026. The latest 12-month change was +1.3%, and the two-year change was +1.4%.
Roswell's latest August index is above its 2025 anchor. The model provides broad city context, not a neighborhood or closing-price result.
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. Roswell 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: (653146.0748233554 - 645037.6431174476) / 645037.6431174476 × 100 = 1.3%
- 2024 to 2026 ZHVI change: (653146.0748233554 - 644231.7502745864) / 644231.7502745864 × 100 = 1.4%
