30 GRASMERE AVENUE 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 four 30 GRASMERE AVENUE sales between November 1996 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 July 2016 sale was for 21% above the HPI. So the extrapolation line tracks at 21% above the HPI over time, until the November 2019 sale, where it rises to 42% above the HPI. The line then continues to track at 42% above the HPI.

What might 30 GRASMERE AVENUE be worth now?

30 GRASMERE AVENUE might now be worth an estimated £247,224.

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 30 GRASMERE AVENUE of £179,000 on 6th November 2019. For the value to have increased from £179,000 to £247,224 over the four years and eleven months to December 2024, the following assumptions must hold true:

• The value of 30 GRASMERE AVENUE has moved in line with the HPI for semi-detached houses in the Blackburn with Darwen local authority area.
• The November 2019 sale price of £179,000 represented a fair market value for the property.
