12A MAPLE ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the St Albans local authority area over time, sourced from the HPI. The three 12A MAPLE ROAD sales between May 1995 and June 2026 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 2015 sale was for 187% above the HPI. So the extrapolation line tracks at 187% above the HPI over time, until the June 2026 sale, where it falls to roughly the same level as the HPI. The line then continues to track in line with the HPI.
