15 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 two 15 HEOL DDU sales from February 2007 and June 2016 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 February 2007 sale was for 20% below the HPI. So the extrapolation line tracks at 20% below the HPI over time, until the June 2016 sale, where it rises to 11% below the HPI. The line then continues to track at 11% below the HPI.

What might 15 HEOL DDU be worth now?

15 HEOL DDU might now be worth an estimated £180,054.

This is based on house price inflation of 52.6%, between June 2016 and February 2025, 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 52.6% inflationary increase is applied to the most recent sale price for 15 HEOL DDU of £118,000 on 28th June 2016. For the value to have increased from £118,000 to £180,054 over the nine years and four months to February 2025, the following assumptions must hold true:

• The value of 15 HEOL DDU has moved in line with the HPI for semi-detached houses in the Swansea local authority area.
• The June 2016 sale price of £118,000 represented a fair market value for the property.
• The size, condition, and specification of 15 HEOL DDU has not materially changed since June 2016.
