7 WEST 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 7 WEST STREET sales from October 2007 and August 2018 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 2007 sale was for 56% above the HPI. So the extrapolation line tracks at 56% above the HPI over time, until the August 2018 sale, where it falls to 22% above the HPI. The line then continues to track at 22% above the HPI.

What might 7 WEST STREET be worth now?

7 WEST STREET might now be worth an estimated £348,939.

This is based on house price inflation of 23.7%, between August 2018 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 23.7% inflationary increase is applied to the most recent sale price for 7 WEST STREET of £282,000 on 31st August 2018. For the value to have increased from £282,000 to £348,939 over the eight years and four months to April 2026, the following assumptions must hold true:

• The value of 7 WEST STREET has moved in line with the HPI for semi-detached houses in the West Northamptonshire local authority area.
• The August 2018 sale price of £282,000 represented a fair market value for the property.
