42 TWYNI TEG 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 42 TWYNI TEG sales from December 2007 and October 2015 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 December 2007 sale was for 21% below the HPI. So the extrapolation line tracks at 21% below the HPI over time, until the October 2015 sale, where it rises to 3% above the HPI. The line then continues to track at 3% above the HPI.

What might 42 TWYNI TEG be worth now?

42 TWYNI TEG might now be worth an estimated £329,937.

This is based on house price inflation of 53.5%, between October 2015 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 53.5% inflationary increase is applied to the most recent sale price for 42 TWYNI TEG of £215,000 on 15th October 2015. For the value to have increased from £215,000 to £329,937 over the eight years and ten months to December 2024, the following assumptions must hold true:

• The value of 42 TWYNI TEG has moved in line with the HPI for detached houses in the Swansea local authority area.
• The October 2015 sale price of £215,000 represented a fair market value for the property.
• The size, condition, and specification of 42 TWYNI TEG has not materially changed since October 2015.
