TWTHILL COTTAGE 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 TWTHILL COTTAGE sales from August 2001 and February 2010 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 August 2001 sale was for 37% below the HPI. So the extrapolation line tracks at 37% below the HPI over time, until the February 2010 sale, where it rises to 25% below the HPI. The line then continues to track at 25% below the HPI.

What might TWTHILL COTTAGE be worth now?

TWTHILL COTTAGE might now be worth an estimated £224,675.

This is based on house price inflation of 51.3%, between February 2010 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 51.3% inflationary increase is applied to the most recent sale price for TWTHILL COTTAGE of £148,500 on 10th February 2010. For the value to have increased from £148,500 to £224,675 over the fifteen years to February 2025, the following assumptions must hold true:

  • The value of TWTHILL COTTAGE has moved in line with the HPI for detached houses in the Gwynedd local authority area.
  • The February 2010 sale price of £148,500 represented a fair market value for the property.
  • The size, condition, and specification of TWTHILL COTTAGE has not materially changed since February 2010.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
