21 BLENHEIM CLOSE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Blackburn with Darwen local authority area over time, sourced from the HPI. The three 21 BLENHEIM CLOSE sales between July 2000 and January 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 December 2009 sale was for 22% above the HPI. So the extrapolation line tracks at 22% above the HPI over time, until the January 2016 sale, where it falls to 21% above the HPI. The line then continues to track at 21% above the HPI.

What might 21 BLENHEIM CLOSE be worth now?

This is based on house price inflation of 60.7%, between January 2016 and December 2024, for semi-detached houses, in the Blackburn with Darwen local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 60.7% inflationary increase is applied to the most recent sale price for 21 BLENHEIM CLOSE of £131,000 on 29th January 2016. For the value to have increased from £131,000 to £210,545 over the seven years and one month to December 2024, the following assumptions must hold true:
