9 BLACKTHORN CLOSE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the South Norfolk local authority area over time, sourced from the HPI. The two 9 BLACKTHORN CLOSE sales from March 2000 and April 2005 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 March 2000 sale was for 34% above the HPI. So the extrapolation line tracks at 34% above the HPI over time, until the April 2005 sale, where it falls to 28% above the HPI. The line then continues to track at 28% above the HPI.

What might 9 BLACKTHORN CLOSE be worth now?

This is based on house price inflation of 98.6%, between April 2005 and October 2025, for semi-detached houses, in the South Norfolk local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 98.6% inflationary increase is applied to the most recent sale price for 9 BLACKTHORN CLOSE of £182,500 on 29th April 2005. For the value to have increased from £182,500 to £362,406 over the nineteen years and six months to October 2025, the following assumptions must hold true:
