CASTLE HOUSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The three CASTLE HOUSE sales between December 1998 and August 2019 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 April 2002 sale was for 83% above the HPI. So the extrapolation line tracks at 83% above the HPI over time, until the August 2019 sale, where it falls to 50% above the HPI. The line then continues to track at 50% above the HPI.

What might CASTLE HOUSE be worth now?

CASTLE HOUSE might now be worth an estimated £712,164.

This is based on house price inflation of 21.7%, between August 2019 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 21.7% inflationary increase is applied to the most recent sale price for CASTLE HOUSE of £585,000 on 23rd August 2019. For the value to have increased from £585,000 to £712,164 over the six years and six months to February 2025, the following assumptions must hold true:

  • The value of CASTLE HOUSE has moved in line with the HPI for detached houses in the West Northamptonshire local authority area.
  • The August 2019 sale price of £585,000 represented a fair market value for the property.
  • The size, condition, and specification of CASTLE HOUSE has not materially changed since August 2019.
