YNYS WEN 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 two YNYS WEN sales from March 2003 and June 2018 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 March 2003 sale was for 37% below the HPI. So the extrapolation line tracks at 37% below the HPI over time, until the June 2018 sale, where it rises to 29% above the HPI. The line then continues to track at 29% above the HPI.

What might YNYS WEN be worth now?

YNYS WEN might now be worth an estimated £382,401.

This is based on house price inflation of 31.9%, between June 2018 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 31.9% inflationary increase is applied to the most recent sale price for YNYS WEN of £290,000 on 15th June 2018. For the value to have increased from £290,000 to £382,401 over the five years and six months to December 2024, the following assumptions must hold true:

• The value of YNYS WEN has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The June 2018 sale price of £290,000 represented a fair market value for the property.
• The size, condition, and specification of YNYS WEN has not materially changed since June 2018.
