15 PORTSTONE CLOSE 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 two 15 PORTSTONE CLOSE sales from April 1999 and July 2009 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 April 1999 sale was for 36% above the HPI. So the extrapolation line tracks at 36% above the HPI over time, until the July 2009 sale, where it falls to 31% above the HPI. The line then continues to track at 31% above the HPI.

What might 15 PORTSTONE CLOSE be worth now?

The 91.9% inflationary increase is applied to the most recent sale price for 15 PORTSTONE CLOSE of £325,000 on 10th July 2009. For the value to have increased from £325,000 to £623,762 over the sixteen years and five months to February 2025, the following assumptions must hold true:
