8 CASTLE CRESCENT Price Paid vs. HPI Average

The below graph shows the average detached house price in the Swansea local authority area over time, sourced from the HPI. The four 8 CASTLE CRESCENT sales between January 2000 and March 2019 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 October 2014 sale was for 261% above the HPI. So the extrapolation line tracks at 261% above the HPI over time, until the March 2019 sale, where it rises to 321% above the HPI. The line then continues to track at 321% above the HPI.

What might 8 CASTLE CRESCENT be worth now?

This is based on house price inflation of 35.5%, between March 2019 and December 2024, for detached houses, in the Swansea local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 35.5% inflationary increase is applied to the most recent sale price for 8 CASTLE CRESCENT of £995,000 on 11th March 2019. For the value to have increased from £995,000 to £1,348,149 over the four years and three months to December 2024, the following assumptions must hold true:
