The below graph shows the average terraced house price in the West Northamptonshire local authority area over time, sourced from the HPI. The five 11 CASTLE MOUNT sales between March 1998 and July 2016 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 June 2008 sale was for 19% above the HPI. So the extrapolation line tracks at 19% above the HPI over time, until the July 2016 sale, where it rises to 22% above the HPI. The line then continues to track at 22% above the HPI.

11 CASTLE MOUNT might now be worth an estimated £286,094.
This is based on house price inflation of 38.2%, between July 2016 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).
The 38.2% inflationary increase is applied to the most recent sale price for 11 CASTLE MOUNT of £207,000 on 29th July 2016. For the value to have increased from £207,000 to £286,094 over the ten years and two months to May 2026, the following assumptions must hold true:
