20 HAREFIELD 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 20 HAREFIELD sales between March 2004 and August 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 April 2008 sale was for 12% below the HPI. So the extrapolation line tracks at 12% below the HPI over time, until the August 2016 sale, where it rises to 2% below the HPI. The line then continues to track at 2% below the HPI.

What might 20 HAREFIELD be worth now?

This is based on house price inflation of 32.3%, between August 2016 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 32.3% inflationary increase is applied to the most recent sale price for 20 HAREFIELD of £350,000 on 19th August 2016. For the value to have increased from £350,000 to £463,001 over the nine years and six months to February 2025, the following assumptions must hold true:
