17 UPPER TAIL Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Three Rivers local authority area over time, sourced from the HPI. The two 17 UPPER TAIL sales from August 2014 and February 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 August 2014 sale was for 19% above the HPI. So the extrapolation line tracks at 19% above the HPI over time, until the February 2025 sale, where it rises to 40% above the HPI. The line then continues to track at 40% above the HPI.
