25 TWYNIAGO 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 three 25 TWYNIAGO sales between February 2015 and January 2024 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 2018 sale was for 43% below the HPI. So the extrapolation line tracks at 43% below the HPI over time, until the January 2024 sale, where it falls to 44% below the HPI. The line then continues to track at 44% below the HPI.

What might 25 TWYNIAGO be worth now?

This is based on house price inflation of 1.7%, between January 2024 and February 2025, 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 1.7% inflationary increase is applied to the most recent sale price for 25 TWYNIAGO of £173,250 on 22nd January 2024. For the value to have increased from £173,250 to £176,198 over the eleven months to February 2025, the following assumptions must hold true:
