13 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 13 PORTMAN PARK sales from June 1999 and March 2007 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 June 1999 sale was for 2% above the HPI. So the extrapolation line tracks at 2% above the HPI over time, until the March 2007 sale, where it rises to 55% above the HPI. The line then continues to track at 55% above the HPI.

What might 13 PORTMAN PARK be worth now?

13 PORTMAN PARK might now be worth an estimated £1,068,879.

This is based on house price inflation of 90.9%, between March 2007 and February 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 90.9% inflationary increase is applied to the most recent sale price for 13 PORTMAN PARK of £560,000 on 1st March 2007. For the value to have increased from £560,000 to £1,068,879 over the eighteen years and one month to February 2025, the following assumptions must hold true:

• The value of 13 PORTMAN PARK has moved in line with the HPI for detached houses in the Tonbridge and Malling local authority area.
• The March 2007 sale price of £560,000 represented a fair market value for the property.
• The size, condition, and specification of 13 PORTMAN PARK has not materially changed since March 2007.
