21 CASTLE MOUNT Price Paid vs. HPI Average

The below graph shows the average detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The four 21 CASTLE MOUNT sales between April 1998 and November 2015 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 2007 sale was for 27% below the HPI. So the extrapolation line tracks at 27% below the HPI over time, until the November 2015 sale, where it rises to 25% below the HPI. The line then continues to track at 25% below the HPI.

What might 21 CASTLE MOUNT be worth now?

21 CASTLE MOUNT might now be worth an estimated £357,004.

This is based on house price inflation of 41.1%, between November 2015 and April 2026, for 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 41.1% inflationary increase is applied to the most recent sale price for 21 CASTLE MOUNT of £253,000 on 20th November 2015. For the value to have increased from £253,000 to £357,004 over the eleven years and seven months to April 2026, the following assumptions must hold true:

• The value of 21 CASTLE MOUNT has moved in line with the HPI for detached houses in the West Northamptonshire local authority area.
• The November 2015 sale price of £253,000 represented a fair market value for the property.
