3 BARN MEWS Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The two 3 BARN MEWS sales from February 1997 and March 2026 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 February 1997 sale was for 58% above the HPI. So the extrapolation line tracks at 58% above the HPI over time, until the March 2026 sale, where it falls to 7% above the HPI. The line then continues to track at 7% above the HPI.

What might 3 BARN MEWS be worth now?

This is based on house price deflation of 0.1%, between March 2026 and April 2026, for semi-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 0.1% deflationary decrease is applied to the most recent sale price for 3 BARN MEWS of £307,000 on 31st March 2026. For the value to have decreased from £307,000 to £306,680 over the eleven months to April 2026, the following assumptions must hold true:

• The March 2026 sale price of £307,000 represented a fair market value for the property.
