9 OTTERTON CLOSE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the St Albans local authority area over time, sourced from the HPI. The four 9 OTTERTON CLOSE sales between July 1998 and March 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 February 2006 sale was for 43% above the HPI. So the extrapolation line tracks at 43% above the HPI over time, until the March 2012 sale, where it falls to 21% above the HPI. The line then continues to track at 21% above the HPI.

What might 9 OTTERTON CLOSE be worth now?

9 OTTERTON CLOSE might now be worth an estimated £886,710.

This is based on house price inflation of 77.3%, between March 2012 and June 2025, for semi-detached houses, in the St Albans local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 77.3% inflationary increase is applied to the most recent sale price for 9 OTTERTON CLOSE of £499,995 on 16th March 2012. For the value to have increased from £499,995 to £886,710 over the twelve years and nine months to June 2025, the following assumptions must hold true:

• The value of 9 OTTERTON CLOSE has moved in line with the HPI for semi-detached houses in the St Albans local authority area.
