25 INSTITUTE ROAD 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 three 25 INSTITUTE ROAD sales between May 2017 and June 2021 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 2019 sale was for 189% above the HPI. So the extrapolation line tracks at 189% above the HPI over time, until the June 2021 sale, where it rises to 313% above the HPI. The line then continues to track at 313% above the HPI.

What might 25 INSTITUTE ROAD be worth now?

25 INSTITUTE ROAD might now be worth an estimated £1,909,850.

This is based on house price inflation of 12%, between June 2021 and December 2024, 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 12% inflationary increase is applied to the most recent sale price for 25 INSTITUTE ROAD of £1,705,000 on 15th June 2021. For the value to have increased from £1,705,000 to £1,909,850 over the two years and six months to December 2024, the following assumptions must hold true:

• The value of 25 INSTITUTE ROAD has moved in line with the HPI for semi-detached houses in the Buckinghamshire local authority area.
• The June 2021 sale price of £1,705,000 represented a fair market value for the property.
• The size, condition, and specification of 25 INSTITUTE ROAD has not materially changed since June 2021.
