The below graph shows the average terraced house price in the West Northamptonshire local authority area over time, sourced from the HPI. The two 11 MORTIMER CLOSE sales from May 1995 and August 2009 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 1995 sale was for 64% above the HPI. So the extrapolation line tracks at 64% above the HPI over time, until the August 2009 sale, where it falls to 23% above the HPI. The line then continues to track at 23% above the HPI.

11 MORTIMER CLOSE might now be worth an estimated £288,267.
This is based on house price inflation of 96.1%, between August 2009 and May 2026, for terraced houses, in the West Northamptonshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
