11 SHELLEY STREET 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 11 SHELLEY STREET sales between September 1995 and May 2024 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 June 2006 sale was for 32% below the HPI. So the extrapolation line tracks at 32% below the HPI over time, until the May 2024 sale, where it rises to 17% below the HPI. The line then continues to track at 17% below the HPI.

What might 11 SHELLEY STREET be worth now?
