5 ASHWELLS 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 5 ASHWELLS sales between December 1997 and July 2010 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 2000 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the July 2010 sale, where it falls to 14% below the HPI. The line then continues to track at 14% below the HPI.

What might 5 ASHWELLS be worth now?

5 ASHWELLS might now be worth an estimated £731,042.

This is based on house price inflation of 70%, between July 2010 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 70% inflationary increase is applied to the most recent sale price for 5 ASHWELLS of £430,000 on 29th July 2010. For the value to have increased from £430,000 to £731,042 over the fifteen years and five months to February 2025, the following assumptions must hold true:

• The value of 5 ASHWELLS has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The July 2010 sale price of £430,000 represented a fair market value for the property.
• The size, condition, and specification of 5 ASHWELLS has not materially changed since July 2010.
