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 20 KEMPTON GARDENS sales between October 2000 and April 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 August 2002 sale was for 14% above the HPI. So the extrapolation line tracks at 14% above the HPI over time, until the April 2006 sale, where it falls to 8% above the HPI. The line then continues to track at 8% above the HPI.

20 KEMPTON GARDENS might now be worth an estimated £359,095.
This is based on house price inflation of 113.7%, between April 2006 and July 2025, 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 113.7% inflationary increase is applied to the most recent sale price for 20 KEMPTON GARDENS of £168,000 on 28th April 2006. For the value to have increased from £168,000 to £359,095 over the eighteen years and nine months to July 2025, the following assumptions must hold true:
