20 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 two 20 DONNAY CLOSE sales from July 1996 and April 2007 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 1996 sale was for 95% above the HPI. So the extrapolation line tracks at 95% above the HPI over time, until the April 2007 sale, where it falls to 92% above the HPI. The line then continues to track at 92% above the HPI.

What might 20 DONNAY CLOSE be worth now?

This is based on house price inflation of 76.6%, between April 2007 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 76.6% inflationary increase is applied to the most recent sale price for 20 DONNAY CLOSE of £905,000 on 4th April 2007. For the value to have increased from £905,000 to £1,598,190 over the sixteen years and four months to December 2024, the following assumptions must hold true:

• The value of 20 DONNAY CLOSE has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The April 2007 sale price of £905,000 represented a fair market value for the property.
