18 DONNAY CLOSE 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 four 18 DONNAY CLOSE sales between November 1995 and November 2020 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 April 2006 sale was for 80% above the HPI. So the extrapolation line tracks at 80% above the HPI over time, until the November 2020 sale, where it falls to 77% above the HPI. The line then continues to track at 77% above the HPI.

What might 18 DONNAY CLOSE be worth now?

18 DONNAY CLOSE might now be worth an estimated £1,471,255.

This is based on house price inflation of 9%, between November 2020 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 9% inflationary increase is applied to the most recent sale price for 18 DONNAY CLOSE of £1,350,000 on 17th November 2020. For the value to have increased from £1,350,000 to £1,471,255 over the three years and eleven months to December 2024, the following assumptions must hold true:

• The value of 18 DONNAY CLOSE has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The November 2020 sale price of £1,350,000 represented a fair market value for the property.
