The below graph shows the average terraced house price in the West Northamptonshire local authority area over time, sourced from the HPI. The two 27 BOSTOCK AVENUE sales from April 2018 and September 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 April 2018 sale was for 25% above the HPI. So the extrapolation line tracks at 25% above the HPI over time, until the September 2021 sale, where it rises to 57% above the HPI. The line then continues to track at 57% above the HPI.

27 BOSTOCK AVENUE might now be worth an estimated £367,653.
