21 DYFFRYN ROAD 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 DYFFRYN ROAD sales between February 1995 and October 2007 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 April 2000 sale was for 13% above the HPI. So the extrapolation line tracks at 13% above the HPI over time, until the October 2007 sale, where it rises to 24% above the HPI. The line then continues to track at 24% above the HPI.

What might 21 DYFFRYN ROAD be worth now?

This is based on house price inflation of 50.3%, between October 2007 and April 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 50.3% inflationary increase is applied to the most recent sale price for 21 DYFFRYN ROAD of £174,950 on 26th October 2007. For the value to have increased from £174,950 to £262,922 over the nineteen years and six months to April 2026, the following assumptions must hold true:

• The October 2007 sale price of £174,950 represented a fair market value for the property.
