166 HERONSWOOD ROAD Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The three 166 HERONSWOOD ROAD sales between May 1998 and May 2018 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 2007 sale was for 13% below the HPI. So the extrapolation line tracks at 13% below the HPI over time, until the May 2018 sale, where it rises to roughly the same level as the HPI. The line then continues to track in line with the HPI.

What might 166 HERONSWOOD ROAD be worth now?
