48 PENN ROAD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Buckinghamshire local authority area over time, sourced from the HPI. The three 48 PENN ROAD sales between July 1999 and December 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 April 2017 sale was for 213% above the HPI. So the extrapolation line tracks at 213% above the HPI over time, until the December 2025 sale, where it rises to 246% above the HPI. The line then continues to track at 246% above the HPI.

What might 48 PENN ROAD be worth now?
