13 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 three 13 OTTERTON CLOSE sales between January 1999 and December 2009 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 November 2000 sale was for 15% above the HPI. So the extrapolation line tracks at 15% above the HPI over time, until the December 2009 sale, where it rises to 62% above the HPI. The line then continues to track at 62% above the HPI.

What might 13 OTTERTON CLOSE be worth now?

This is based on house price inflation of 103.4%, between December 2009 and February 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 103.4% inflationary increase is applied to the most recent sale price for 13 OTTERTON CLOSE of £599,950 on 7th December 2009. For the value to have increased from £599,950 to £1,220,282 over the sixteen years and ten months to February 2025, the following assumptions must hold true:
