4 MOUNTFIELD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Tonbridge and Malling local authority area over time, sourced from the HPI. The four 4 MOUNTFIELD sales between December 2013 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 November 2018 sale was for 2% above the HPI. So the extrapolation line tracks at 2% above the HPI over time, until the February 2025 sale, where it falls to 8% below the HPI. The line then continues to track at 8% below the HPI.

What might 4 MOUNTFIELD be worth now?

This is based on house price deflation of 3.3%, between February 2025 and June 2025, for detached houses, in the Tonbridge and Malling local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 3.3% deflationary decrease is applied to the most recent sale price for 4 MOUNTFIELD of £650,000 on 5th February 2025. For the value to have decreased from £650,000 to £628,332 over the eight months to June 2025, the following assumptions must hold true:

• The value of 4 MOUNTFIELD has moved in line with the HPI for detached houses in the Tonbridge and Malling local authority area.
• The February 2025 sale price of £650,000 represented a fair market value for the property.
• The size, condition, and specification of 4 MOUNTFIELD has not materially changed since February 2025.
