ISHTA Price Paid vs. HPI Average

The below graph shows the average detached house price in the Spelthorne local authority area over time, sourced from the HPI. The two ISHTA sales from November 2005 and April 2011 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 2005 sale was for 14% below the HPI. So the extrapolation line tracks at 14% below the HPI over time, until the April 2011 sale, where it rises to 15% above the HPI. The line then continues to track at 15% above the HPI.

What might ISHTA be worth now?

ISHTA might now be worth an estimated £917,790.

This is based on house price inflation of 83.6%, between April 2011 and February 2025, for detached houses, in the Spelthorne local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 83.6% inflationary increase is applied to the most recent sale price for ISHTA of £500,000 on 19th April 2011. For the value to have increased from £500,000 to £917,790 over the fourteen years and two months to February 2025, the following assumptions must hold true:

• The value of ISHTA has moved in line with the HPI for detached houses in the Spelthorne local authority area.
• The April 2011 sale price of £500,000 represented a fair market value for the property.
• The size, condition, and specification of ISHTA has not materially changed since April 2011.
