19 TRINITY AVENUE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Buckinghamshire local authority area over time, sourced from the HPI. The four 19 TRINITY AVENUE sales between October 1998 and May 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 45% above the HPI. So the extrapolation line tracks at 45% above the HPI over time, until the May 2026 sale, where it rises to 119% above the HPI. The line then continues to track at 119% above the HPI.
