ALLYN HOUSE 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 two ALLYN HOUSE sales from September 1996 and April 2004 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 September 1996 sale was for 57% above the HPI. So the extrapolation line tracks at 57% above the HPI over time, until the April 2004 sale, where it falls to 49% above the HPI. The line then continues to track at 49% above the HPI.

What might ALLYN HOUSE be worth now?

ALLYN HOUSE might now be worth an estimated £1,259,997.

This is based on house price inflation of 111.8%, between April 2004 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 111.8% inflationary increase is applied to the most recent sale price for ALLYN HOUSE of £595,000 on 15th April 2004. For the value to have increased from £595,000 to £1,259,997 over the 21 years and two months to February 2025, the following assumptions must hold true:

• The value of ALLYN HOUSE has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The April 2004 sale price of £595,000 represented a fair market value for the property.
• The size, condition, and specification of ALLYN HOUSE has not materially changed since April 2004.
