The below graph shows the average detached house price in the South Gloucestershire local authority area over time, sourced from the HPI. The two 40 BOUNDARY ROAD sales from November 1997 and October 1999 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the November 1997 sale was for 4% below the HPI. So the extrapolation line tracks at 4% below the HPI over time, until the October 1999 sale, where it falls to 12% below the HPI. The line then continues to track at 12% below the HPI.
40 BOUNDARY ROAD might now be worth an estimated £493,061.
This is based on house price inflation of 332.5%, between October 1999 and February 2025, for detached houses, in the South Gloucestershire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 332.5% inflationary increase is applied to the most recent sale price for 40 BOUNDARY ROAD of £114,000 on 1st October 1999. For the value to have increased from £114,000 to £493,061 over the 26 years and eight months to February 2025, the following assumptions must hold true:
