40 LOCKGATE 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 two 40 LOCKGATE ROAD sales from July 2014 and June 2017 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 July 2014 sale was for 67% above the HPI. So the extrapolation line tracks at 67% above the HPI over time, until the June 2017 sale, where it falls to 31% above the HPI. The line then continues to track at 31% above the HPI.

What might 40 LOCKGATE ROAD be worth now?

40 LOCKGATE ROAD might now be worth an estimated £374,883.

This is based on house price inflation of 31.5%, between June 2017 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 31.5% inflationary increase is applied to the most recent sale price for 40 LOCKGATE ROAD of £285,000 on 22nd June 2017. For the value to have increased from £285,000 to £374,883 over the nine years and two months to April 2026, the following assumptions must hold true:

  • The value of 40 LOCKGATE ROAD has moved in line with the HPI for semi-detached houses in the West Northamptonshire local authority area.
  • The June 2017 sale price of £285,000 represented a fair market value for the property.
  • The size, condition, and specification of 40 LOCKGATE ROAD has not materially changed since June 2017.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
