7 BANC YR EITHIN 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 7 BANC YR EITHIN sales from May 2014 and September 2025 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 2014 sale was for 18% above the HPI. So the extrapolation line tracks at 18% above the HPI over time, until the September 2025 sale, where it rises to 40% above the HPI. The line then continues to track at 40% above the HPI.

This is based on house price deflation of 0.6%, between September 2025 and April 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 0.6% deflationary decrease is applied to the most recent sale price for 7 BANC YR EITHIN of £465,000 on 19th September 2025. For the value to have decreased from £465,000 to £462,221 over the one year and five months to April 2026, the following assumptions must hold true:
