1 BLACKDOWN AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Sheffield local authority area over time, sourced from the HPI. The two 1 BLACKDOWN AVENUE sales from November 2001 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 November 2001 sale was for 21% below the HPI. So the extrapolation line tracks at 21% below the HPI over time, until the May 2024 sale, where it rises to 18% below the HPI. The line then continues to track at 18% below the HPI.
