MAYFIELD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Carmarthenshire local authority area over time, sourced from the HPI. The two MAYFIELD sales from May 2021 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 2021 sale was for 14% above the HPI. So the extrapolation line tracks at 14% above the HPI over time, until the January 2024 sale, where it rises to 44% above the HPI. The line then continues to track at 44% above the HPI.

What might MAYFIELD be worth now?

MAYFIELD might now be worth an estimated £398,280.

This is based on house price inflation of 4.1%, between January 2024 and March 2025, for 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 4.1% inflationary increase is applied to the most recent sale price for MAYFIELD of £382,500 on 26th January 2024. For the value to have increased from £382,500 to £398,280 over the ten months to March 2025, the following assumptions must hold true:

• The value of MAYFIELD has moved in line with the HPI for detached houses in the Carmarthenshire local authority area.
• The January 2024 sale price of £382,500 represented a fair market value for the property.
• The size, condition, and specification of MAYFIELD has not materially changed since January 2024.
