17 HEOL DDU Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Swansea local authority area over time, sourced from the HPI. The four 17 HEOL DDU sales between November 1996 and May 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 July 2005 sale was for 7% below the HPI. So the extrapolation line tracks at 7% below the HPI over time, until the May 2015 sale, where it rises to 19% above the HPI. The line then continues to track at 19% above the HPI.

What might 17 HEOL DDU be worth now?

17 HEOL DDU might now be worth an estimated £245,437.

This is based on house price inflation of 63.6%, between May 2015 and December 2024, for semi-detached houses, in the Swansea local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 63.6% inflationary increase is applied to the most recent sale price for 17 HEOL DDU of £150,000 on 29th May 2015. For the value to have increased from £150,000 to £245,437 over the eight years and five months to December 2024, the following assumptions must hold true:

• The value of 17 HEOL DDU has moved in line with the HPI for semi-detached houses in the Swansea local authority area.
• The May 2015 sale price of £150,000 represented a fair market value for the property.
• The size, condition, and specification of 17 HEOL DDU has not materially changed since May 2015.
