The below graph shows the average detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The four THE GRAMMAR HOUSE sales between March 2002 and October 2022 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 2014 sale was for 378% above the HPI. So the extrapolation line tracks at 378% above the HPI over time, until the October 2022 sale, where it rises to 481% above the HPI. The line then continues to track at 481% above the HPI.
THE GRAMMAR HOUSE might now be worth an estimated £2,754,378.
This is based on house price inflation of 0.2%, between October 2022 and February 2025, for detached 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 0.2% inflationary increase is applied to the most recent sale price for THE GRAMMAR HOUSE of £2,750,000 on 17th October 2022. For the value to have increased from £2,750,000 to £2,754,378 over the three years and eight months to February 2025, the following assumptions must hold true:
