11 NEW STREET Price Paid vs. HPI Average

The below graph shows the average detached house price in the Neath Port Talbot local authority area over time, sourced from the HPI. The two 11 NEW STREET sales from January 1997 and September 1999 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 1997 sale was for 19% above the HPI. So the extrapolation line tracks at 19% above the HPI over time, until the September 1999 sale, where it falls to 15% above the HPI. The line then continues to track at 15% above the HPI.

What might 11 NEW STREET be worth now?

The 312.5% inflationary increase is applied to the most recent sale price for 11 NEW STREET of £69,999 on 23rd September 1999. For the value to have increased from £69,999 to £288,758 over the 26 years and seven months to February 2025, the following assumptions must hold true:
