170 BLACKFEN ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Bexley local authority area over time, sourced from the HPI. The two 170 BLACKFEN ROAD sales from November 2007 and May 2022 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 November 2007 sale was for 9% above the HPI. So the extrapolation line tracks at 9% above the HPI over time, until the May 2022 sale, where it falls to 11% below the HPI. The line then continues to track at 11% below the HPI.

What might 170 BLACKFEN ROAD be worth now?

This is based on house price inflation of 2.7%, between May 2022 and February 2025, for 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 2.7% inflationary increase is applied to the most recent sale price for 170 BLACKFEN ROAD of £620,000 on 31st May 2022. For the value to have increased from £620,000 to £636,799 over the three years and three months to February 2025, the following assumptions must hold true:
