18 MANDER CLOSE 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 five 18 MANDER CLOSE sales between June 2003 and March 2025 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 March 2016 sale was for 9% below the HPI. So the extrapolation line tracks at 9% below the HPI over time, until the March 2025 sale, where it falls to 11% below the HPI. The line then continues to track at 11% below the HPI.

What might 18 MANDER CLOSE be worth now?

This is based on house price inflation of 2.3%, between March 2025 and May 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 2.3% inflationary increase is applied to the most recent sale price for 18 MANDER CLOSE of £249,000 on 27th March 2025. For the value to have increased from £249,000 to £254,632 over the ten months to May 2026, the following assumptions must hold true:
