The below graph shows the average terraced house price in the Cheshire West and Chester local authority area over time, sourced from the HPI. The four 20 BLACKTHORNE AVENUE sales between November 1997 and March 2021 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 April 2014 sale was for 6% above the HPI. So the extrapolation line tracks at 6% above the HPI over time, until the March 2021 sale, where it falls to 11% below the HPI. The line then continues to track at 11% below the HPI.

20 BLACKTHORNE AVENUE might now be worth an estimated £179,565.
This is based on house price inflation of 20.5%, between March 2021 and July 2025, for terraced houses, in the Cheshire West and Chester local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 20.5% inflationary increase is applied to the most recent sale price for 20 BLACKTHORNE AVENUE of £149,000 on 29th March 2021. For the value to have increased from £149,000 to £179,565 over the three years and eight months to July 2025, the following assumptions must hold true:
