The below graph shows the average semi-detached house price in the Sefton local authority area over time, sourced from the HPI. The two 9 MARDALE CLOSE sales from November 1996 and June 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 November 1996 sale was for 5% above the HPI. So the extrapolation line tracks at 5% above the HPI over time, until the June 2025 sale, which was also at 5% above the HPI.

9 MARDALE CLOSE might now be worth an estimated £254,823.
This is based on house price inflation of 1.9%, between June 2025 and August 2025, for semi-detached houses, in the Sefton local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 1.9% inflationary increase is applied to the most recent sale price for 9 MARDALE CLOSE of £250,000 on 16th June 2025. For the value to have increased from £250,000 to £254,823 over the ten months to August 2025, the following assumptions must hold true:
