33 BLACKDOWN 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 three 33 BLACKDOWN sales between November 1996 and August 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 July 2007 sale was for 5% below the HPI. So the extrapolation line tracks at 5% below the HPI over time, until the August 2025 sale, where it rises to 30% above the HPI. The line then continues to track at 30% above the HPI.

What might 33 BLACKDOWN be worth now?

33 BLACKDOWN might now be worth an estimated £418,917.

This is based on house price deflation of 0.3%, between August 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 0.3% deflationary decrease is applied to the most recent sale price for 33 BLACKDOWN of £420,000 on 1st August 2025. For the value to have decreased from £420,000 to £418,917 over the one year and four months to April 2026, the following assumptions must hold true:

• The value of 33 BLACKDOWN has moved in line with the HPI for semi-detached houses in the Milton Keynes local authority area.
• The August 2025 sale price of £420,000 represented a fair market value for the property.
