ROSE COTTAGE 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 ROSE COTTAGE sales from April 2006 and October 2024 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 April 2006 sale was for 31% below the HPI. So the extrapolation line tracks at 31% below the HPI over time, until the October 2024 sale, where it rises to 7% below the HPI. The line then continues to track at 7% below the HPI.

What might ROSE COTTAGE be worth now?

ROSE COTTAGE might now be worth an estimated £787,326.

This is based on house price deflation of 1.7%, between October 2024 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 1.7% deflationary decrease is applied to the most recent sale price for ROSE COTTAGE of £801,050 on 18th October 2024. For the value to have decreased from £801,050 to £787,326 over the one year and eight months to February 2025, the following assumptions must hold true:

• The value of ROSE COTTAGE has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The October 2024 sale price of £801,050 represented a fair market value for the property.
• The size, condition, and specification of ROSE COTTAGE has not materially changed since October 2024.
