12 OVERHILLS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Milton Keynes local authority area over time, sourced from the HPI. The two 12 OVERHILLS sales from August 1996 and April 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 August 1996 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the April 2026 sale, where it falls to 1% above the HPI. The line then continues to track at 1% above the HPI.
