27 ABBEY AVENUE 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 27 ABBEY AVENUE sales between June 2000 and July 2019 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 June 2005 sale was for 1% below the HPI. So the extrapolation line tracks at 1% below the HPI over time, until the July 2019 sale, where it rises to 3% above the HPI. The line then continues to track at 3% above the HPI.
