18 THORPE AVENUE 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 two 18 THORPE AVENUE sales from July 1995 and July 2017 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 July 1995 sale was for 11% below the HPI. So the extrapolation line tracks at 11% below the HPI over time, until the July 2017 sale, where it falls to 22% below the HPI. The line then continues to track at 22% below the HPI.

What might 18 THORPE AVENUE be worth now?

This is based on house price inflation of 20.1%, between July 2017 and December 2024, 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 20.1% inflationary increase is applied to the most recent sale price for 18 THORPE AVENUE of £437,000 on 3rd July 2017. For the value to have increased from £437,000 to £524,956 over the six years and seven months to December 2024, the following assumptions must hold true:
