666 OBELISK RISE 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 666 OBELISK RISE sales from September 2001 and November 2005 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 September 2001 sale was for 3% below the HPI. So the extrapolation line tracks at 3% below the HPI over time, until the November 2005 sale, where it falls to 10% below the HPI. The line then continues to track at 10% below the HPI.

What might 666 OBELISK RISE be worth now?

666 OBELISK RISE might now be worth an estimated £256,841.

This is based on house price inflation of 83.5%, between November 2005 and February 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 83.5% inflationary increase is applied to the most recent sale price for 666 OBELISK RISE of £140,000 on 4th November 2005. For the value to have increased from £140,000 to £256,841 over the twenty years and nine months to February 2025, the following assumptions must hold true:

• The value of 666 OBELISK RISE has moved in line with the HPI for semi-detached houses in the West Northamptonshire local authority area.
• The November 2005 sale price of £140,000 represented a fair market value for the property.
