1 GLENALLA ROAD 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 two 1 GLENALLA ROAD sales from May 2016 and August 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 2016 sale was for 9% above the HPI. So the extrapolation line tracks at 9% above the HPI over time, until the August 2024 sale, where it rises to 13% above the HPI. The line then continues to track at 13% above the HPI.

What might 1 GLENALLA ROAD be worth now?

1 GLENALLA ROAD might now be worth an estimated £209,209.

This is based on house price inflation of 5.7%, between August 2024 and August 2025, 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 5.7% inflationary increase is applied to the most recent sale price for 1 GLENALLA ROAD of £198,000 on 21st August 2024. For the value to have increased from £198,000 to £209,209 over the one year to August 2025, the following assumptions must hold true:

• The value of 1 GLENALLA ROAD has moved in line with the HPI for semi-detached houses in the Carmarthenshire local authority area.
• The August 2024 sale price of £198,000 represented a fair market value for the property.
