99 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 99 BLACKFEN ROAD sales between February 2000 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 December 2014 sale was for 5% below the HPI. So the extrapolation line tracks at 5% below the HPI over time, until the June 2021 sale, where it rises to 2% above the HPI. The line then continues to track at 2% above the HPI.

What might 99 BLACKFEN ROAD be worth now?

99 BLACKFEN ROAD might now be worth an estimated £527,550.

This is based on house price inflation of 13.5%, between June 2021 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 13.5% inflationary increase is applied to the most recent sale price for 99 BLACKFEN ROAD of £465,000 on 25th June 2021. For the value to have increased from £465,000 to £527,550 over the four years and four months to February 2025, the following assumptions must hold true:
