1 SIERRA DRIVE 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 1 SIERRA DRIVE sales from July 2015 and August 2017 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 2015 sale was for 41% below the HPI. So the extrapolation line tracks at 41% below the HPI over time, until the August 2017 sale, where it falls to 44% below the HPI. The line then continues to track at 44% below the HPI.

What might 1 SIERRA DRIVE be worth now?

This is based on house price inflation of 13.6%, between August 2017 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 13.6% inflationary increase is applied to the most recent sale price for 1 SIERRA DRIVE of £420,000 on 4th August 2017. For the value to have increased from £420,000 to £477,013 over the eight years and six months to February 2025, the following assumptions must hold true:
