20 HEOL LLANELLI Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Carmarthenshire local authority area over time, sourced from the HPI. The three 20 HEOL LLANELLI sales between September 2003 and August 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 December 2022 sale was for 33% below the HPI. So the extrapolation line tracks at 33% below the HPI over time, until the August 2025 sale, where it falls to 61% below the HPI. The line then continues to track at 61% below the HPI.

What might 20 HEOL LLANELLI be worth now?

20 HEOL LLANELLI might now be worth an estimated £69,977.

This is based on house price inflation of 3.7%, between August 2025 and May 2026, for semi-detached houses, in the Carmarthenshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 3.7% inflationary increase is applied to the most recent sale price for 20 HEOL LLANELLI of £67,500 on 28th August 2025. For the value to have increased from £67,500 to £69,977 over the one year and three months to May 2026, the following assumptions must hold true:
