TWEEDSMUIR 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 TWEEDSMUIR sales between May 1999 and May 2006 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 June 1999 sale was for 19% above the HPI. So the extrapolation line tracks at 19% above the HPI over time, until the May 2006 sale, where it rises to 40% above the HPI. The line then continues to track at 40% above the HPI.

What might TWEEDSMUIR be worth now?

TWEEDSMUIR might now be worth an estimated £1,162,060.

This is based on house price inflation of 92.9%, between May 2006 and December 2024, 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 92.9% inflationary increase is applied to the most recent sale price for TWEEDSMUIR of £602,500 on 11th May 2006. For the value to have increased from £602,500 to £1,162,060 over the seventeen years and five months to December 2024, the following assumptions must hold true:

• The value of TWEEDSMUIR has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The May 2006 sale price of £602,500 represented a fair market value for the property.
• The size, condition, and specification of TWEEDSMUIR has not materially changed since May 2006.
