27 PENMYNYDD 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 27 PENMYNYDD sales from October 2005 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 October 2005 sale was for 12% above the HPI. So the extrapolation line tracks at 12% above the HPI over time, until the March 2021 sale, where it falls to 3% above the HPI. The line then continues to track at 3% above the HPI.

What might 27 PENMYNYDD be worth now?

27 PENMYNYDD might now be worth an estimated £218,272.

This is based on house price inflation of 27.3%, between March 2021 and April 2026, 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 27.3% inflationary increase is applied to the most recent sale price for 27 PENMYNYDD of £171,500 on 31st March 2021. For the value to have increased from £171,500 to £218,272 over the four years and eleven months to April 2026, the following assumptions must hold true:

  • The value of 27 PENMYNYDD has moved in line with the HPI for semi-detached houses in the Swansea local authority area.
  • The March 2021 sale price of £171,500 represented a fair market value for the property.
  • The size, condition, and specification of 27 PENMYNYDD has not materially changed since March 2021.
