12 DERWLAS 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 three 12 DERWLAS sales between July 1997 and July 2005 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 2002 sale was for 16% above the HPI. So the extrapolation line tracks at 16% above the HPI over time, until the July 2005 sale, where it falls to 8% above the HPI. The line then continues to track at 8% above the HPI.

What might 12 DERWLAS be worth now?

12 DERWLAS might now be worth an estimated £219,127.

This is based on house price inflation of 67.3%, between July 2005 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 67.3% inflationary increase is applied to the most recent sale price for 12 DERWLAS of £130,995 on 8th July 2005. For the value to have increased from £130,995 to £219,127 over the twenty years and five months to February 2025, the following assumptions must hold true:

• The value of 12 DERWLAS has moved in line with the HPI for semi-detached houses in the Swansea local authority area.
• The July 2005 sale price of £130,995 represented a fair market value for the property.
• The size, condition, and specification of 12 DERWLAS has not materially changed since July 2005.
