131 BLACKFEN ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Bexley local authority area over time, sourced from the HPI. The four 131 BLACKFEN ROAD sales between January 1997 and March 2023 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 2019 sale was for 15% below the HPI. So the extrapolation line tracks at 15% below the HPI over time, until the March 2023 sale, where it rises to 9% below the HPI. The line then continues to track at 9% below the HPI.

What might 131 BLACKFEN ROAD be worth now?

This is based on house price inflation of 0.1%, between March 2023 and February 2025, for semi-detached houses, in the Bexley local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 0.1% inflationary increase is applied to the most recent sale price for 131 BLACKFEN ROAD of £470,000 on 30th March 2023. For the value to have increased from £470,000 to £470,284 over the two years and one month to February 2025, the following assumptions must hold true:
