18 WEST COMMON Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Buckinghamshire local authority area over time, sourced from the HPI. The three 18 WEST COMMON sales between November 1995 and May 2006 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 July 1997 sale was for 171% above the HPI. So the extrapolation line tracks at 171% above the HPI over time, until the May 2006 sale, where it falls to 108% above the HPI. The line then continues to track at 108% above the HPI.

What might 18 WEST COMMON be worth now?

18 WEST COMMON might now be worth an estimated £962,187.

This is based on house price inflation of 93.2%, between May 2006 and December 2024, for semi-detached houses, in the Buckinghamshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 93.2% inflationary increase is applied to the most recent sale price for 18 WEST COMMON of £498,000 on 23rd May 2006. For the value to have increased from £498,000 to £962,187 over the seventeen years and five months to December 2024, the following assumptions must hold true:

• The value of 18 WEST COMMON has moved in line with the HPI for semi-detached houses in the Buckinghamshire local authority area.
• The May 2006 sale price of £498,000 represented a fair market value for the property.
• The size, condition, and specification of 18 WEST COMMON has not materially changed since May 2006.
