The below graph shows the average detached house price in the Carmarthenshire local authority area over time, sourced from the HPI. The single 21 PENDDERI ROAD sale from October 2010 has been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, preceding and following the October 2010 sale, had it maintained the same 1% margin above the HPI (as a percentage) throughout.

21 PENDDERI ROAD might now be worth an estimated £181,019.

The 64.6% inflationary increase is applied to the most recent sale price for 21 PENDDERI ROAD of £110,000 on 28th October 2010. For the value to have increased from £110,000 to £181,019 over the sixteen years and five months to May 2026, the following assumptions must hold true:
