1 TAN YR ONNEN Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Gwynedd local authority area over time, sourced from the HPI. The three 1 TAN YR ONNEN sales between September 1996 and August 2022 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 2018 sale was for 14% above the HPI. So the extrapolation line tracks at 14% above the HPI over time, until the August 2022 sale, where it rises to 25% above the HPI. The line then continues to track at 25% above the HPI.

What might 1 TAN YR ONNEN be worth now?

1 TAN YR ONNEN might now be worth an estimated £258,242.

This is based on house price inflation of 1.3%, between August 2022 and June 2025, for semi-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 1.3% inflationary increase is applied to the most recent sale price for 1 TAN YR ONNEN of £255,000 on 15th August 2022. For the value to have increased from £255,000 to £258,242 over the three years and two months to June 2025, the following assumptions must hold true:

• The value of 1 TAN YR ONNEN has moved in line with the HPI for semi-detached houses in the Gwynedd local authority area.
• The August 2022 sale price of £255,000 represented a fair market value for the property.
