20 BUTTON END Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the South Cambridgeshire local authority area over time, sourced from the HPI. The four 20 BUTTON END sales between October 1999 and August 2022 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 August 2017 sale was for 19% above the HPI. So the extrapolation line tracks at 19% above the HPI over time, until the August 2022 sale, where it falls to 12% above the HPI. The line then continues to track at 12% above the HPI.

What might 20 BUTTON END be worth now?

20 BUTTON END might now be worth an estimated £465,815.

This is based on house price inflation of 7.1%, between August 2022 and December 2024, for semi-detached houses, in the South Cambridgeshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 7.1% inflationary increase is applied to the most recent sale price for 20 BUTTON END of £435,000 on 11th August 2022. For the value to have increased from £435,000 to £465,815 over the one year and eight months to December 2024, the following assumptions must hold true:

• The value of 20 BUTTON END has moved in line with the HPI for semi-detached houses in the South Cambridgeshire local authority area.
• The August 2022 sale price of £435,000 represented a fair market value for the property.
• The size, condition, and specification of 20 BUTTON END has not materially changed since August 2022.
