1 BLACKTHORN CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the St Albans local authority area over time, sourced from the HPI. The two 1 BLACKTHORN CLOSE sales from May 2010 and July 2012 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 May 2010 sale roughly matched the HPI. So the extrapolation line tracks roughly in line with the HPI over time, until the July 2012 sale, where it falls to 14% below the HPI. The line then continues to track at 14% below the HPI.
