16 PEN Y CAE 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 16 PEN Y CAE sales between January 1999 and January 2015 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 5% below the HPI. So the extrapolation line tracks at 5% below the HPI over time, until the January 2015 sale, where it falls to 13% below the HPI. The line then continues to track at 13% below the HPI.

What might 16 PEN Y CAE be worth now?

16 PEN Y CAE might now be worth an estimated £241,077.

This is based on house price inflation of 60.7%, between January 2015 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 60.7% inflationary increase is applied to the most recent sale price for 16 PEN Y CAE of £150,000 on 16th January 2015. For the value to have increased from £150,000 to £241,077 over the nine years and eleven months to February 2025, the following assumptions must hold true:

• The value of 16 PEN Y CAE has moved in line with the HPI for detached houses in the Carmarthenshire local authority area.
• The January 2015 sale price of £150,000 represented a fair market value for the property.
• The size, condition, and specification of 16 PEN Y CAE has not materially changed since January 2015.
