20 BRYN CASEG 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 three 20 BRYN CASEG sales between October 2001 and March 2020 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 2007 sale was for 53% below the HPI. So the extrapolation line tracks at 53% below the HPI over time, until the March 2020 sale, where it rises to 24% below the HPI. The line then continues to track at 24% below the HPI.

What might 20 BRYN CASEG be worth now?

20 BRYN CASEG might now be worth an estimated £229,110.

This is based on house price inflation of 27.3%, between March 2020 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 27.3% inflationary increase is applied to the most recent sale price for 20 BRYN CASEG of £180,000 on 20th March 2020. For the value to have increased from £180,000 to £229,110 over the five years and one month to February 2025, the following assumptions must hold true:

  • The value of 20 BRYN CASEG has moved in line with the HPI for detached houses in the Gwynedd local authority area.
  • The March 2020 sale price of £180,000 represented a fair market value for the property.
  • The size, condition, and specification of 20 BRYN CASEG has not materially changed since March 2020.
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.
