18 ALLERTON ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Sefton local authority area over time, sourced from the HPI. The three 18 ALLERTON ROAD sales between August 1996 and August 2007 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 2005 sale was for 94% above the HPI. So the extrapolation line tracks at 94% above the HPI over time, until the August 2007 sale, where it rises to 107% above the HPI. The line then continues to track at 107% above the HPI.

What might 18 ALLERTON ROAD be worth now?

This is based on house price inflation of 46.5%, between August 2007 and February 2025, for 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 46.5% inflationary increase is applied to the most recent sale price for 18 ALLERTON ROAD of £537,950 on 9th August 2007. For the value to have increased from £537,950 to £788,242 over the eighteen years and six months to February 2025, the following assumptions must hold true:
