9 LON Y PLAS 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 four 9 LON Y PLAS sales between February 1995 and April 2018 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 October 2009 sale was for 3% above the HPI. So the extrapolation line tracks at 3% above the HPI over time, until the April 2018 sale, where it rises to 5% above the HPI. The line then continues to track at 5% above the HPI.

What might 9 LON Y PLAS be worth now?

9 LON Y PLAS might now be worth an estimated £289,685.

This is based on house price inflation of 48.6%, between April 2018 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 48.6% inflationary increase is applied to the most recent sale price for 9 LON Y PLAS of £195,000 on 11th April 2018. For the value to have increased from £195,000 to £289,685 over the seven years and two months to February 2025, the following assumptions must hold true:

• The value of 9 LON Y PLAS has moved in line with the HPI for detached houses in the Carmarthenshire local authority area.
• The April 2018 sale price of £195,000 represented a fair market value for the property.
