The below graph shows the average terraced house price in the Blackburn with Darwen local authority area over time, sourced from the HPI. The two 21 MOSS STREET sales from August 1997 and July 2008 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 August 1997 sale was for 59% above the HPI. So the extrapolation line tracks at 59% above the HPI over time, until the July 2008 sale, where it falls to 1% above the HPI. The line then continues to track at 1% above the HPI.

21 MOSS STREET might now be worth an estimated £132,461.
This is based on house price inflation of 39.4%, between July 2008 and August 2025, for terraced 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 39.4% inflationary increase is applied to the most recent sale price for 21 MOSS STREET of £95,000 on 11th July 2008. For the value to have increased from £95,000 to £132,461 over the sixteen years and eleven months to August 2025, the following assumptions must hold true:
