21 DENHAM AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Carmarthenshire local authority area over time, sourced from the HPI. The three 21 DENHAM AVENUE sales between September 1995 and October 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 January 2002 sale was for 34% above the HPI. So the extrapolation line tracks at 34% above the HPI over time, until the October 2018 sale, where it falls to 27% above the HPI. The line then continues to track at 27% above the HPI.

What might 21 DENHAM AVENUE be worth now?

21 DENHAM AVENUE might now be worth an estimated £228,393.

This is based on house price inflation of 44.6%, between October 2018 and June 2025, for semi-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 44.6% inflationary increase is applied to the most recent sale price for 21 DENHAM AVENUE of £158,000 on 11th October 2018. For the value to have increased from £158,000 to £228,393 over the seven years and four months to June 2025, the following assumptions must hold true:
