1A PORTMAN PARK 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 1A PORTMAN PARK sales from December 2005 and March 2012 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 December 2005 sale was for 26% below the HPI. So the extrapolation line tracks at 26% below the HPI over time, until the March 2012 sale, where it rises to 22% below the HPI. The line then continues to track at 22% below the HPI.

What might 1A PORTMAN PARK be worth now?

1A PORTMAN PARK might now be worth an estimated £527,843.

This is based on house price inflation of 74.5%, between March 2012 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 74.5% inflationary increase is applied to the most recent sale price for 1A PORTMAN PARK of £302,500 on 26th March 2012. For the value to have increased from £302,500 to £527,843 over the eleven years and three months to December 2024, the following assumptions must hold true:

• The value of 1A PORTMAN PARK has moved in line with the HPI for detached houses in the Tonbridge and Malling local authority area.
• The March 2012 sale price of £302,500 represented a fair market value for the property.
