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.
