TAN Y MARIAN 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 TAN Y MARIAN sales from September 2000 and August 2016 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 September 2000 sale was for 132% above the HPI. So the extrapolation line tracks at 132% above the HPI over time, until the August 2016 sale, where it falls to 84% above the HPI. The line then continues to track at 84% above the HPI.

What might TAN Y MARIAN be worth now?

TAN Y MARIAN might now be worth an estimated £555,643.

This is based on house price inflation of 42.5%, between August 2016 and February 2025, 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 42.5% inflationary increase is applied to the most recent sale price for TAN Y MARIAN of £390,000 on 18th August 2016. For the value to have increased from £390,000 to £555,643 over the nine years and six months to February 2025, the following assumptions must hold true:

• The value of TAN Y MARIAN has moved in line with the HPI for detached houses in the Gwynedd local authority area.
• The August 2016 sale price of £390,000 represented a fair market value for the property.
• The size, condition, and specification of TAN Y MARIAN has not materially changed since August 2016.
