17 TOWNSIDE 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 five 17 TOWNSIDE sales between August 2000 and November 2022 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 2020 sale was for 42% below the HPI. So the extrapolation line tracks at 42% below the HPI over time, until the November 2022 sale, where it falls to 45% below the HPI. The line then continues to track at 45% below the HPI.

What might 17 TOWNSIDE be worth now?

This is based on house price deflation of 3.7%, between November 2022 and December 2024, 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 3.7% deflationary decrease is applied to the most recent sale price for 17 TOWNSIDE of £477,700 on 25th November 2022. For the value to have decreased from £477,700 to £459,896 over the one year and eleven months to December 2024, the following assumptions must hold true:
