The below graph shows the average detached house price in the Milton Keynes local authority area over time, sourced from the HPI. The three 20 NAPIER STREET sales between May 1996 and September 2008 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 May 1999 sale was for 15% below the HPI. So the extrapolation line tracks at 15% below the HPI over time, until the September 2008 sale, where it falls to 23% below the HPI. The line then continues to track at 23% below the HPI.
20 NAPIER STREET might now be worth an estimated £432,618.
This is based on house price inflation of 96.6%, between September 2008 and February 2025, 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).
