156 HEOL DULAIS 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 156 HEOL DULAIS sales from May 1995 and September 1999 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 May 1995 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the September 1999 sale, where it falls to 43% below the HPI. The line then continues to track at 43% below the HPI.

What might 156 HEOL DULAIS be worth now?

This is based on house price inflation of 328.8%, between September 1999 and May 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 328.8% inflationary increase is applied to the most recent sale price for 156 HEOL DULAIS of £27,995 on 23rd September 1999. For the value to have increased from £27,995 to £120,048 over the 27 years and four months to May 2026, the following assumptions must hold true:
