| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|

The below graph shows the average semi-detached house price in the Milton Keynes local authority area over time, sourced from the HPI. The two 121 WALTON END sales from July 1996 and March 2006 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 1996 sale was for 125% above the HPI. So the extrapolation line tracks at 125% above the HPI over time, until the March 2006 sale, where it falls to 115% above the HPI. The line then continues to track at 115% above the HPI.

121 WALTON END might now be worth an estimated £708,254.
This is based on house price inflation of 111.4%, between March 2006 and May 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 111.4% inflationary increase is applied to the most recent sale price for 121 WALTON END of £335,000 on 31st March 2006. For the value to have increased from £335,000 to £708,254 over the nineteen years and ten months to May 2026, the following assumptions must hold true:
