171 HIGH STREET 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 171 HIGH STREET sales from May 2014 and September 2020 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 May 2014 sale was for 16% above the HPI. So the extrapolation line tracks at 16% above the HPI over time, until the September 2020 sale, where it falls to 6% above the HPI. The line then continues to track at 6% above the HPI.

What might 171 HIGH STREET be worth now?

This is based on house price inflation of 21.2%, between September 2020 and December 2024, 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 21.2% inflationary increase is applied to the most recent sale price for 171 HIGH STREET of £248,000 on 1st September 2020. For the value to have increased from £248,000 to £300,686 over the three years and nine months to December 2024, the following assumptions must hold true:
