TYDDYN GORONWY Price Paid vs. HPI Average

The below graph shows the average detached house price in the Isle of Anglesey local authority area over time, sourced from the HPI. The three TYDDYN GORONWY sales between February 1999 and December 2008 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 February 2002 sale was for 51% above the HPI. So the extrapolation line tracks at 51% above the HPI over time, until the December 2008 sale, where it rises to 74% above the HPI. The line then continues to track at 74% above the HPI.

What might TYDDYN GORONWY be worth now?

TYDDYN GORONWY might now be worth an estimated £555,721.

This is based on house price inflation of 58.8%, between December 2008 and July 2026, for detached houses, in the Isle of Anglesey local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 58.8% inflationary increase is applied to the most recent sale price for TYDDYN GORONWY of £350,000 on 19th December 2008. For the value to have increased from £350,000 to £555,721 over the eighteen years and five months to July 2026, the following assumptions must hold true:

  • The value of TYDDYN GORONWY has moved in line with the HPI for detached houses in the Isle of Anglesey local authority area.
  • The December 2008 sale price of £350,000 represented a fair market value for the property.
  • The size, condition, and specification of TYDDYN GORONWY has not materially changed since December 2008.
