15A ALLONBY WAY Price Paid vs. HPI Average

The below graph shows the average detached house price in the Buckinghamshire local authority area over time, sourced from the HPI. The two 15A ALLONBY WAY sales from November 2003 and December 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 November 2003 sale was for 9% below the HPI. So the extrapolation line tracks at 9% below the HPI over time, until the December 2006 sale, where it falls to 12% below the HPI. The line then continues to track at 12% below the HPI.

What might 15A ALLONBY WAY be worth now?

This is based on house price inflation of 81.9%, between December 2006 and February 2025, for 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 81.9% inflationary increase is applied to the most recent sale price for 15A ALLONBY WAY of £410,000 on 6th December 2006. For the value to have increased from £410,000 to £745,775 over the nineteen years and ten months to February 2025, the following assumptions must hold true:
