14 MOUNTAIN ASH AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Southend-on-Sea local authority area over time, sourced from the HPI. The three 14 MOUNTAIN ASH AVENUE sales between October 2003 and January 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 February 2010 sale was for 26% below the HPI. So the extrapolation line tracks at 26% below the HPI over time, until the January 2025 sale, where it falls to 34% below the HPI. The line then continues to track at 34% below the HPI.

What might 14 MOUNTAIN ASH AVENUE be worth now?
