15 KNOTTOCKS DRIVE 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 15 KNOTTOCKS DRIVE sales between November 1996 and February 2017 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 2011 sale was for 39% above the HPI. So the extrapolation line tracks at 39% above the HPI over time, until the February 2017 sale, where it rises to 99% above the HPI. The line then continues to track at 99% above the HPI.

What might 15 KNOTTOCKS DRIVE be worth now?

15 KNOTTOCKS DRIVE might now be worth an estimated £1,685,172.

This is based on house price inflation of 16.2%, between February 2017 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 16.2% inflationary increase is applied to the most recent sale price for 15 KNOTTOCKS DRIVE of £1,450,000 on 2nd February 2017. For the value to have increased from £1,450,000 to £1,685,172 over the eight years to February 2025, the following assumptions must hold true:

• The February 2017 sale price of £1,450,000 represented a fair market value for the property.
