3 GRINDON 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 3 GRINDON sales from August 2023 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 August 2023 sale was for 14% below the HPI. So the extrapolation line tracks at 14% below the HPI over time, until the November 2025 sale, where it falls to 18% below the HPI. The line then continues to track at 18% below the HPI.

What might 3 GRINDON be worth now?

3 GRINDON might now be worth an estimated £459,921.

This is based on house price inflation of 1.6%, between November 2025 and July 2026, for 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 1.6% inflationary increase is applied to the most recent sale price for 3 GRINDON of £452,500 on 7th November 2025. For the value to have increased from £452,500 to £459,921 over the one year and four months to July 2026, the following assumptions must hold true:

• The value of 3 GRINDON has moved in line with the HPI for detached houses in the Milton Keynes local authority area.
