20 BLENHEIM SQUARE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Lincoln local authority area over time, sourced from the HPI. The three 20 BLENHEIM SQUARE sales between February 2007 and December 2021 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 2013 sale was for 17% above the HPI. So the extrapolation line tracks at 17% above the HPI over time, until the December 2021 sale, where it falls to 1% below the HPI. The line then continues to track at 1% below the HPI.

What might 20 BLENHEIM SQUARE be worth now?
