23 WILLIAM GAMMON DRIVE 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 two 23 WILLIAM GAMMON DRIVE sales from December 2005 and January 2023 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 December 2005 sale was for 27% above the HPI. So the extrapolation line tracks at 27% above the HPI over time, until the January 2023 sale, where it falls to 3% below the HPI. The line then continues to track at 3% below the HPI.

What might 23 WILLIAM GAMMON DRIVE be worth now?

23 WILLIAM GAMMON DRIVE might now be worth an estimated £305,408.

This is based on house price inflation of 0.5%, between January 2023 and February 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 0.5% inflationary increase is applied to the most recent sale price for 23 WILLIAM GAMMON DRIVE of £304,000 on 12th January 2023. For the value to have increased from £304,000 to £305,408 over the one year and eleven months to February 2025, the following assumptions must hold true:

  • The value of 23 WILLIAM GAMMON DRIVE has moved in line with the HPI for detached houses in the Swansea local authority area.
  • The January 2023 sale price of £304,000 represented a fair market value for the property.
  • The size, condition, and specification of 23 WILLIAM GAMMON DRIVE has not materially changed since January 2023.
