The below graph shows the average semi-detached house price in the Tonbridge and Malling local authority area over time, sourced from the HPI. The two 18 PORTER AVENUE sales from February 2014 and June 2021 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 2014 sale was for 77% above the HPI. So the extrapolation line tracks at 77% above the HPI over time, until the June 2021 sale, where it rises to 87% above the HPI. The line then continues to track at 87% above the HPI.
18 PORTER AVENUE might now be worth an estimated £789,643.
This is based on house price inflation of 12.8%, between June 2021 and February 2025, for semi-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 12.8% inflationary increase is applied to the most recent sale price for 18 PORTER AVENUE of £700,000 on 25th June 2021. For the value to have increased from £700,000 to £789,643 over the four years and four months to February 2025, the following assumptions must hold true:
