23 HEOL TYDDYN Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Caerphilly local authority area over time, sourced from the HPI. The two 23 HEOL TYDDYN sales from June 2001 and November 2009 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 2001 sale was for 54% above the HPI. So the extrapolation line tracks at 54% above the HPI over time, until the November 2009 sale, where it falls to 32% above the HPI. The line then continues to track at 32% above the HPI.

What might 23 HEOL TYDDYN be worth now?

The 91.7% inflationary increase is applied to the most recent sale price for 23 HEOL TYDDYN of £134,950 on 19th November 2009. For the value to have increased from £134,950 to £258,764 over the fourteen years and eleven months to December 2024, the following assumptions must hold true:
