15 GRIMSDELLS LANE 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 two 15 GRIMSDELLS LANE sales from November 2022 and November 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 November 2022 sale was for 25% below the HPI. So the extrapolation line tracks at 25% below the HPI over time, until the November 2025 sale, where it rises to 70% above the HPI. The line then continues to track at 70% above the HPI.
