SONNENEGG 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 SONNENEGG sales from December 2001 and July 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 December 2001 sale was for 46% above the HPI. So the extrapolation line tracks at 46% above the HPI over time, until the July 2017 sale, where it falls to 29% above the HPI. The line then continues to track at 29% above the HPI.

What might SONNENEGG be worth now?

SONNENEGG might now be worth an estimated £1,092,221.

This is based on house price inflation of 14.7%, between July 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 14.7% inflationary increase is applied to the most recent sale price for SONNENEGG of £952,500 on 5th July 2017. For the value to have increased from £952,500 to £1,092,221 over the eight years and five months to February 2025, the following assumptions must hold true:

• The value of SONNENEGG has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The July 2017 sale price of £952,500 represented a fair market value for the property.
• The size, condition, and specification of SONNENEGG has not materially changed since July 2017.
