21 COTTON END 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 four 21 COTTON END sales between November 1996 and May 2010 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 December 2005 sale was for 34% above the HPI. So the extrapolation line tracks at 34% above the HPI over time, until the May 2010 sale, where it rises to 43% above the HPI. The line then continues to track at 43% above the HPI.

What might 21 COTTON END be worth now?

The 81.7% inflationary increase is applied to the most recent sale price for 21 COTTON END of £223,000 on 28th May 2010. For the value to have increased from £223,000 to £405,274 over the thirteen years and five months to December 2024, the following assumptions must hold true:
