1 CLOS TREVENTY 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 1 CLOS TREVENTY sales between February 2010 and May 2019 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 2014 sale was for 49% above the HPI. So the extrapolation line tracks at 49% above the HPI over time, until the May 2019 sale, where it falls to 43% above the HPI. The line then continues to track at 43% above the HPI.

What might 1 CLOS TREVENTY be worth now?

1 CLOS TREVENTY might now be worth an estimated £399,528.

This is based on house price inflation of 41.4%, between May 2019 and June 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 41.4% inflationary increase is applied to the most recent sale price for 1 CLOS TREVENTY of £282,500 on 1st May 2019. For the value to have increased from £282,500 to £399,528 over the five years and eleven months to June 2025, the following assumptions must hold true:

  • The value of 1 CLOS TREVENTY has moved in line with the HPI for detached houses in the Carmarthenshire local authority area.
  • The May 2019 sale price of £282,500 represented a fair market value for the property.
  • The size, condition, and specification of 1 CLOS TREVENTY has not materially changed since May 2019.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
