8 COB LANE CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The three 8 COB LANE CLOSE sales between July 1999 and September 2022 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 July 2003 sale was for 19% below the HPI. So the extrapolation line tracks at 19% below the HPI over time, until the September 2022 sale, where it falls to 27% below the HPI. The line then continues to track at 27% below the HPI.
