1 DRAGONTAIL 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 two 1 DRAGONTAIL sales from June 2013 and September 2024 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 June 2013 sale was for 93% above the HPI. So the extrapolation line tracks at 93% above the HPI over time, until the September 2024 sale, where it falls to 82% above the HPI. The line then continues to track at 82% above the HPI.

What might 1 DRAGONTAIL be worth now?

1 DRAGONTAIL might now be worth an estimated £842,221.

This is based on house price deflation of 0.9%, between September 2024 and June 2025, 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 0.9% deflationary decrease is applied to the most recent sale price for 1 DRAGONTAIL of £850,000 on 27th September 2024. For the value to have decreased from £850,000 to £842,221 over the one year and three months to June 2025, the following assumptions must hold true:

• The value of 1 DRAGONTAIL has moved in line with the HPI for semi-detached houses in the Buckinghamshire local authority area.
• The September 2024 sale price of £850,000 represented a fair market value for the property.
• The size, condition, and specification of 1 DRAGONTAIL has not materially changed since September 2024.
