304 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 304 BLACKFEN ROAD sales between April 1998 and October 2016 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 2004 sale was for 7% above the HPI. So the extrapolation line tracks at 7% above the HPI over time, until the October 2016 sale, where it falls to 4% below the HPI. The line then continues to track at 4% below the HPI.

What might 304 BLACKFEN ROAD be worth now?

304 BLACKFEN ROAD might now be worth an estimated £507,865.

This is based on house price inflation of 28.6%, between October 2016 and May 2026, 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 28.6% inflationary increase is applied to the most recent sale price for 304 BLACKFEN ROAD of £395,000 on 21st October 2016. For the value to have increased from £395,000 to £507,865 over the ten years and five months to May 2026, the following assumptions must hold true:

• The value of 304 BLACKFEN ROAD has moved in line with the HPI for semi-detached houses in the Bexley local authority area.
• The October 2016 sale price of £395,000 represented a fair market value for the property.
