12 CASTLEROCK DRIVE Price Paid vs. HPI Average

The below graph shows the average detached house price in the North Northamptonshire local authority area over time, sourced from the HPI. The two 12 CASTLEROCK DRIVE sales from October 2017 and November 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 October 2017 sale was for 15% below the HPI. So the extrapolation line tracks at 15% below the HPI over time, until the November 2019 sale, where it falls to 17% below the HPI. The line then continues to track at 17% below the HPI.

What might 12 CASTLEROCK DRIVE be worth now?

This is based on house price inflation of 24.4%, between November 2019 and December 2024, for detached houses, in the North Northamptonshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 24.4% inflationary increase is applied to the most recent sale price for 12 CASTLEROCK DRIVE of £273,000 on 22nd November 2019. For the value to have increased from £273,000 to £339,624 over the four years and eleven months to December 2024, the following assumptions must hold true:
