20 WASHINGTON STREET Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the West Lindsey local authority area over time, sourced from the HPI. The four 20 WASHINGTON STREET sales between November 2005 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 August 2023 sale was for 64% below the HPI. So the extrapolation line tracks at 64% below the HPI over time, until the May 2024 sale, where it rises to 41% above the HPI. The line then continues to track at 41% above the HPI.
