ROWARDEN 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 five ROWARDEN sales between April 2007 and February 2025 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 February 2018 sale was for 39% below the HPI. So the extrapolation line tracks at 39% below the HPI over time, until the February 2025 sale, where it rises to 15% below the HPI. The line then continues to track at 15% below the HPI.

What might ROWARDEN be worth now?

ROWARDEN might now be worth an estimated £713,117.

This is based on house price deflation of 0.3%, between February 2025 and March 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 0.3% deflationary decrease is applied to the most recent sale price for ROWARDEN of £715,000 on 1st February 2025. For the value to have decreased from £715,000 to £713,117 over the eleven months to March 2025, the following assumptions must hold true:

• The value of ROWARDEN has moved in line with the HPI for detached houses in the Buckinghamshire local authority area.
• The February 2025 sale price of £715,000 represented a fair market value for the property.
• The size, condition, and specification of ROWARDEN has not materially changed since February 2025.
