18 HEOL PENYCAE 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 18 HEOL PENYCAE sales from September 1995 and October 1998 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 1995 sale was for 13% below the HPI. So the extrapolation line tracks at 13% below the HPI over time, until the October 1998 sale, where it falls to 23% below the HPI. The line then continues to track at 23% below the HPI.

What might 18 HEOL PENYCAE be worth now?

This is based on house price inflation of 320%, between October 1998 and May 2026, 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 320% inflationary increase is applied to the most recent sale price for 18 HEOL PENYCAE of £60,000 on 9th October 1998. For the value to have increased from £60,000 to £251,972 over the 28 years and five months to May 2026, the following assumptions must hold true:
