DERLWYN 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 three DERLWYN sales between April 2015 and March 2021 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 June 2019 sale was for 11% above the HPI. So the extrapolation line tracks at 11% above the HPI over time, until the March 2021 sale, where it rises to 13% above the HPI. The line then continues to track at 13% above the HPI.

What might DERLWYN be worth now?

DERLWYN might now be worth an estimated £313,638.

This is based on house price inflation of 23%, between March 2021 and February 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 23% inflationary increase is applied to the most recent sale price for DERLWYN of £255,000 on 19th March 2021. For the value to have increased from £255,000 to £313,638 over the four years and one month to February 2025, the following assumptions must hold true:

• The value of DERLWYN has moved in line with the HPI for detached houses in the Carmarthenshire local authority area.
• The March 2021 sale price of £255,000 represented a fair market value for the property.
• The size, condition, and specification of DERLWYN has not materially changed since March 2021.
