1 THE 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 1 THE CLOSE sales between November 2005 and July 2015 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 August 2009 sale was for 92% above the HPI. So the extrapolation line tracks at 92% above the HPI over time, until the July 2015 sale, where it falls to 63% above the HPI. The line then continues to track at 63% above the HPI.

What might 1 THE CLOSE be worth now?

1 THE CLOSE might now be worth an estimated £1,231,049.

This is based on house price inflation of 38.7%, between July 2015 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 38.7% inflationary increase is applied to the most recent sale price for 1 THE CLOSE of £887,500 on 9th July 2015. For the value to have increased from £887,500 to £1,231,049 over the ten years and five months to February 2025, the following assumptions must hold true:

• The value of 1 THE CLOSE has moved in line with the HPI for semi-detached houses in the St Albans local authority area.
• The July 2015 sale price of £887,500 represented a fair market value for the property.
• The size, condition, and specification of 1 THE CLOSE has not materially changed since July 2015.
