23A SUNNYBANK 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 23A SUNNYBANK sales from August 2020 and May 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 August 2020 sale was for 118% above the HPI. So the extrapolation line tracks at 118% above the HPI over time, until the May 2022 sale, where it rises to 122% above the HPI. The line then continues to track at 122% above the HPI.

What might 23A SUNNYBANK be worth now?

23A SUNNYBANK might now be worth an estimated £1,040,294.

This is based on house price inflation of 6.7%, between May 2022 and February 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 6.7% inflationary increase is applied to the most recent sale price for 23A SUNNYBANK of £975,000 on 6th May 2022. For the value to have increased from £975,000 to £1,040,294 over the three years and three months to February 2025, the following assumptions must hold true:

  • The value of 23A SUNNYBANK has moved in line with the HPI for semi-detached houses in the Buckinghamshire local authority area.
  • The May 2022 sale price of £975,000 represented a fair market value for the property.
  • The size, condition, and specification of 23A SUNNYBANK has not materially changed since May 2022.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
