25 MOUNT STREET 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 25 MOUNT STREET sales from January 2015 and September 2017 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 2015 sale was for 20% below the HPI. So the extrapolation line tracks at 20% below the HPI over time, until the September 2017 sale, where it rises to 10% below the HPI. The line then continues to track at 10% below the HPI.

What might 25 MOUNT STREET be worth now?

This is based on house price inflation of 40.9%, between September 2017 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 40.9% inflationary increase is applied to the most recent sale price for 25 MOUNT STREET of £205,000 on 4th September 2017. For the value to have increased from £205,000 to £288,842 over the six years and nine months to December 2024, the following assumptions must hold true:
