12 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 two 12 BLACKTOWN GARDENS sales from June 2007 and August 2020 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 June 2007 sale was for 5% below the HPI. So the extrapolation line tracks at 5% below the HPI over time, until the August 2020 sale, where it rises to 7% above the HPI. The line then continues to track at 7% above the HPI.
