MILL BARN 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 MILL BARN sales from March 1997 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 March 1997 sale was for 86% above the HPI. So the extrapolation line tracks at 86% above the HPI over time, until the September 2020 sale, where it rises to 392% above the HPI. The line then continues to track at 392% above the HPI.

What might MILL BARN be worth now?

MILL BARN might now be worth an estimated £1,394,312.

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 MILL BARN of £1,150,000 on 4th September 2020. For the value to have increased from £1,150,000 to £1,394,312 over the three years and nine months to December 2024, the following assumptions must hold true:

  • The value of MILL BARN has moved in line with the HPI for semi-detached houses in the West Northamptonshire local authority area.
  • The September 2020 sale price of £1,150,000 represented a fair market value for the property.
  • The size, condition, and specification of MILL BARN has not materially changed since September 2020.
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.
