3 LLYS GWYR 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 3 LLYS GWYR sales from April 2009 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 April 2009 sale was for 148% above the HPI. So the extrapolation line tracks at 148% above the HPI over time, until the March 2019 sale, where it falls to 146% above the HPI. The line then continues to track at 146% above the HPI.

What might 3 LLYS GWYR be worth now?

3 LLYS GWYR might now be worth an estimated £777,447.

This is based on house price inflation of 33.4%, between March 2019 and February 2025, 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 33.4% inflationary increase is applied to the most recent sale price for 3 LLYS GWYR of £583,000 on 11th March 2019. For the value to have increased from £583,000 to £777,447 over the six years and one month to February 2025, the following assumptions must hold true:

• The value of 3 LLYS GWYR has moved in line with the HPI for detached houses in the Swansea local authority area.
• The March 2019 sale price of £583,000 represented a fair market value for the property.
