21 CEFN HELYG 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 21 CEFN HELYG sales from February 1996 and July 2003 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 February 1996 sale was for 72% above the HPI. So the extrapolation line tracks at 72% above the HPI over time, until the July 2003 sale, where it falls to 59% above the HPI. The line then continues to track at 59% above the HPI.

What might 21 CEFN HELYG be worth now?

This is based on house price inflation of 148.7%, between July 2003 and December 2024, 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 148.7% inflationary increase is applied to the most recent sale price for 21 CEFN HELYG of £204,995 on 31st July 2003. For the value to have increased from £204,995 to £509,799 over the twenty years and seven months to December 2024, the following assumptions must hold true:
