The below graph shows the average detached house price in the Dartford local authority area over time, sourced from the HPI. The two 1 PORTMAN CLOSE sales from July 1998 and April 2018 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 1998 sale was for 26% below the HPI. So the extrapolation line tracks at 26% below the HPI over time, until the April 2018 sale, where it rises to 3% above the HPI. The line then continues to track at 3% above the HPI.
1 PORTMAN CLOSE might now be worth an estimated £736,190.
This is based on house price inflation of 17.8%, between April 2018 and December 2024, for detached houses, in the Dartford local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 17.8% inflationary increase is applied to the most recent sale price for 1 PORTMAN CLOSE of £625,000 on 23rd April 2018. For the value to have increased from £625,000 to £736,190 over the five years and four months to December 2024, the following assumptions must hold true:
