6 TREETOPS 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 6 TREETOPS CLOSE sales between March 2019 and July 2025 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 2022 sale was for 31% above the HPI. So the extrapolation line tracks at 31% above the HPI over time, until the July 2025 sale, where it falls to 26% above the HPI. The line then continues to track at 26% above the HPI.

What might 6 TREETOPS CLOSE be worth now?

6 TREETOPS CLOSE might now be worth an estimated £231,640.

This is based on house price inflation of 5.3%, between July 2025 and April 2026, 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 5.3% inflationary increase is applied to the most recent sale price for 6 TREETOPS CLOSE of £220,000 on 21st July 2025. For the value to have increased from £220,000 to £231,640 over the one year and three months to April 2026, the following assumptions must hold true:
