6 TREGAEAN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Gwynedd local authority area over time, sourced from the HPI. The three 6 TREGAEAN sales between August 1996 and November 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 July 1999 sale roughly matched the HPI. So the extrapolation line tracks roughly in line with the HPI over time, until the November 2017 sale, where it falls to 29% below the HPI. The line then continues to track at 29% below the HPI.

What might 6 TREGAEAN be worth now?

6 TREGAEAN might now be worth an estimated £210,383.

This is based on house price inflation of 29.1%, between November 2017 and December 2024, for detached houses, in the Gwynedd local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 29.1% inflationary increase is applied to the most recent sale price for 6 TREGAEAN of £163,000 on 29th November 2017. For the value to have increased from £163,000 to £210,383 over the six years and eleven months to December 2024, the following assumptions must hold true:

• The value of 6 TREGAEAN has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The November 2017 sale price of £163,000 represented a fair market value for the property.
• The size, condition, and specification of 6 TREGAEAN has not materially changed since November 2017.
