OASIS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Somerset local authority area over time, sourced from the HPI. The three OASIS sales between December 2006 and November 2021 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 June 2007 sale was for 8% below the HPI. So the extrapolation line tracks at 8% below the HPI over time, until the November 2021 sale, where it falls to 16% below the HPI. The line then continues to track at 16% below the HPI.

What might OASIS be worth now?

OASIS might now be worth an estimated £386,406.

This is based on house price inflation of 8.8%, between November 2021 and May 2026, for detached houses, in the Somerset local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 8.8% inflationary increase is applied to the most recent sale price for OASIS of £355,000 on 9th November 2021. For the value to have increased from £355,000 to £386,406 over the five years and six months to May 2026, the following assumptions must hold true:

• The value of OASIS has moved in line with the HPI for detached houses in the Somerset local authority area.
• The November 2021 sale price of £355,000 represented a fair market value for the property.
• The size, condition, and specification of OASIS has not materially changed since November 2021.
