11 TAIR GWAUN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Vale of Glamorgan local authority area over time, sourced from the HPI. The three 11 TAIR GWAUN sales between December 2003 and October 2023 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 September 2005 sale was for 30% above the HPI. So the extrapolation line tracks at 30% above the HPI over time, until the October 2023 sale, where it rises to 46% above the HPI. The line then continues to track at 46% above the HPI.

What might 11 TAIR GWAUN be worth now?

The 1.6% inflationary increase is applied to the most recent sale price for 11 TAIR GWAUN of £735,000 on 6th October 2023. For the value to have increased from £735,000 to £746,638 over the ten months to December 2024, the following assumptions must hold true:
