18 MARINE WALK 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 two 18 MARINE WALK sales from March 2000 and February 2020 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 March 2000 sale was for 133% above the HPI. So the extrapolation line tracks at 133% above the HPI over time, until the February 2020 sale, where it falls to 80% above the HPI. The line then continues to track at 80% above the HPI.

What might 18 MARINE WALK be worth now?

This is based on house price inflation of 32%, between February 2020 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 32% inflationary increase is applied to the most recent sale price for 18 MARINE WALK of £437,000 on 7th February 2020. For the value to have increased from £437,000 to £576,964 over the three years and two months to December 2024, the following assumptions must hold true:
