11 BLACKTOWN GARDENS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Newport local authority area over time, sourced from the HPI. The three 11 BLACKTOWN GARDENS sales between June 2007 and August 2017 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 September 2014 sale was for 10% above the HPI. So the extrapolation line tracks at 10% above the HPI over time, until the August 2017 sale, where it falls to 2% above the HPI. The line then continues to track at 2% above the HPI.
