9 TROY STREET 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 two 9 TROY STREET sales from February 2010 and November 2019 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 February 2010 sale was for 5% below the HPI. So the extrapolation line tracks at 5% below the HPI over time, until the November 2019 sale, where it falls to 21% below the HPI. The line then continues to track at 21% below the HPI.

What might 9 TROY STREET be worth now?

This is based on house price inflation of 38.1%, between November 2019 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 38.1% inflationary increase is applied to the most recent sale price for 9 TROY STREET of £100,000 on 18th November 2019. For the value to have increased from £100,000 to £138,114 over the four years and eleven months to December 2024, the following assumptions must hold true:
