4 DERWLAS Price Paid vs. HPI Average

The below graph shows the average detached house price in the Swansea local authority area over time, sourced from the HPI. The five 4 DERWLAS sales between May 1997 and November 2017 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 April 2009 sale was for 11% below the HPI. So the extrapolation line tracks at 11% below the HPI over time, until the November 2017 sale, where it rises to 1% above the HPI. The line then continues to track at 1% above the HPI.

What might 4 DERWLAS be worth now?

4 DERWLAS might now be worth an estimated £323,124.

This is based on house price inflation of 41.7%, between November 2017 and March 2025, for 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 41.7% inflationary increase is applied to the most recent sale price for 4 DERWLAS of £228,000 on 13th November 2017. For the value to have increased from £228,000 to £323,124 over the eight years and eight months to March 2025, the following assumptions must hold true:

• The value of 4 DERWLAS has moved in line with the HPI for detached houses in the Swansea local authority area.
• The November 2017 sale price of £228,000 represented a fair market value for the property.
• The size, condition, and specification of 4 DERWLAS has not materially changed since November 2017.
