3 COMMONSIDE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Buckinghamshire local authority area over time, sourced from the HPI. The four 3 COMMONSIDE sales between May 2003 and March 2026 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 2015 sale was for 18% above the HPI. So the extrapolation line tracks at 18% above the HPI over time, until the March 2026 sale, where it rises to 28% above the HPI. The line then continues to track at 28% above the HPI.

What might 3 COMMONSIDE be worth now?

3 COMMONSIDE might now be worth an estimated £602,146.

This is based on house price inflation of 0.4%, between March 2026 and April 2026, for semi-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 0.4% inflationary increase is applied to the most recent sale price for 3 COMMONSIDE of £600,000 on 6th March 2026. For the value to have increased from £600,000 to £602,146 over the eleven months to April 2026, the following assumptions must hold true:

• The value of 3 COMMONSIDE has moved in line with the HPI for semi-detached houses in the Buckinghamshire local authority area.
• The March 2026 sale price of £600,000 represented a fair market value for the property.
• The size, condition, and specification of 3 COMMONSIDE has not materially changed since March 2026.
