The below graph shows the average detached house price in the Milton Keynes local authority area over time, sourced from the HPI. The three 11 WINDSOR CASTLE STREET sales between March 2020 and August 2025 have been plotted on the graph.

For example, the March 2024 sale was for 8% below the HPI. So the extrapolation line tracks at 8% below the HPI over time, until the August 2025 sale, where it falls to 11% below the HPI.
