21A SOUTH PARK 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 three 21A SOUTH PARK sales between June 1999 and November 2016 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 January 2005 sale was for 131% above the HPI. So the extrapolation line tracks at 131% above the HPI over time, until the November 2016 sale, where it falls to 127% above the HPI. The line then continues to track at 127% above the HPI.

What might 21A SOUTH PARK be worth now?

21A SOUTH PARK might now be worth an estimated £1,921,009.

This is based on house price inflation of 17.5%, between November 2016 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 17.5% inflationary increase is applied to the most recent sale price for 21A SOUTH PARK of £1,635,000 on 15th November 2016. For the value to have increased from £1,635,000 to £1,921,009 over the nine years and nine months to February 2025, the following assumptions must hold true:

• The value of 21A SOUTH PARK has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The November 2016 sale price of £1,635,000 represented a fair market value for the property.
• The size, condition, and specification of 21A SOUTH PARK has not materially changed since November 2016.
