Dates are this site's observation dates. “New” means first seen, while a removed listing does not necessarily indicate a completed transaction and may include withdrawals. Listing duration is an estimate based on the information date, update date, and first observation date, and may differ from the actual listing start date. Days with unconfirmed collection or unit aggregation are treated as missing and are not connected by lines.

How to Read the Figures, Calculation Method, and Sources
- Indicative nearby land value
- Prices for the listed points are weighted by the inverse of each point's stored distance from the building. For points with verified coordinates, map and list distances are straight-line measurements from the building's current coordinates. If those coordinates were updated, they may differ from the distances used in the calculation. This is not a site valuation adjusted for land use or road conditions.
- Change from previous year
- Year-on-year changes at the same locations are weighted by distance. “—” means no comparable value is available.
- 5-year annual average (CAGR)
- This converts the change since five years ago into an annual rate, assuming the same rate each year. It is not the total five-year increase. Only comparable points are weighted by distance.
