9 TRINITY ROAD 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 three 9 TRINITY ROAD sales between December 2015 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 October 2020 sale was for 16% above the HPI. So the extrapolation line tracks at 16% above the HPI over time, until the March 2025 sale, where it falls to 15% above the HPI. The line then continues to track at 15% above the HPI.

What might 9 TRINITY ROAD be worth now?

This is based on house price inflation of 0.6%, between March 2025 and June 2025, 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 0.6% inflationary increase is applied to the most recent sale price for 9 TRINITY ROAD of £325,000 on 14th March 2025. For the value to have increased from £325,000 to £327,003 over the nine months to June 2025, the following assumptions must hold true:
