13 THE MOUNT Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Milton Keynes local authority area over time, sourced from the HPI. The four 13 THE MOUNT sales between May 1999 and September 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 September 2020 sale was for 26% below the HPI. So the extrapolation line tracks at 26% below the HPI over time, until the September 2025 sale, where it rises to 23% below the HPI. The line then continues to track at 23% below the HPI.

What might 13 THE MOUNT be worth now?

13 THE MOUNT might now be worth an estimated £246,043.

This is based on house price inflation of 0.4%, between September 2025 and April 2026, for semi-detached houses, in the Milton Keynes local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 0.4% inflationary increase is applied to the most recent sale price for 13 THE MOUNT of £245,000 on 23rd September 2025. For the value to have increased from £245,000 to £246,043 over the one year and five months to April 2026, the following assumptions must hold true:

• The value of 13 THE MOUNT has moved in line with the HPI for semi-detached houses in the Milton Keynes local authority area.
• The September 2025 sale price of £245,000 represented a fair market value for the property.
• The size, condition, and specification of 13 THE MOUNT has not materially changed since September 2025.
