21 ROCK TERRACE 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 21 ROCK TERRACE sales between May 1997 and April 2004 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 September 1999 sale was for 29% below the HPI. So the extrapolation line tracks at 29% below the HPI over time, until the April 2004 sale, where it rises to 16% below the HPI. The line then continues to track at 16% below the HPI.

What might 21 ROCK TERRACE be worth now?

21 ROCK TERRACE might now be worth an estimated £173,764.

This is based on house price inflation of 110.6%, between April 2004 and December 2024, 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 110.6% inflationary increase is applied to the most recent sale price for 21 ROCK TERRACE of £82,500 on 19th April 2004. For the value to have increased from £82,500 to £173,764 over the nineteen years and four months to December 2024, the following assumptions must hold true:

• The value of 21 ROCK TERRACE has moved in line with the HPI for semi-detached houses in the Swansea local authority area.
• The April 2004 sale price of £82,500 represented a fair market value for the property.
• The size, condition, and specification of 21 ROCK TERRACE has not materially changed since April 2004.
