THE TRIANGLE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Doncaster local authority area over time, sourced from the HPI. The two THE TRIANGLE sales from November 2009 and March 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 November 2009 sale was for 45% above the HPI. So the extrapolation line tracks at 45% above the HPI over time, until the March 2021 sale, where it rises to 98% above the HPI. The line then continues to track at 98% above the HPI.

What might THE TRIANGLE be worth now?

THE TRIANGLE might now be worth an estimated £501,251.

This is based on house price inflation of 17.9%, between March 2021 and December 2024, for detached houses, in the Doncaster local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 17.9% inflationary increase is applied to the most recent sale price for THE TRIANGLE of £425,000 on 5th March 2021. For the value to have increased from £425,000 to £501,251 over the two years and three months to December 2024, the following assumptions must hold true:

• The value of THE TRIANGLE has moved in line with the HPI for detached houses in the Doncaster local authority area.
• The March 2021 sale price of £425,000 represented a fair market value for the property.
• The size, condition, and specification of THE TRIANGLE has not materially changed since March 2021.
