BRIALLU Price Paid vs. HPI Average

The below graph shows the average detached house price in the Powys local authority area over time, sourced from the HPI. The three BRIALLU sales between July 2002 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 2015 sale was for 14% below the HPI. So the extrapolation line tracks at 14% below the HPI over time, until the June 2018 sale, where it rises to 13% below the HPI. The line then continues to track at 13% below the HPI.

What might BRIALLU be worth now?

BRIALLU might now be worth an estimated £284,441.

This is based on house price inflation of 36.8%, between June 2018 and May 2026, for detached houses, in the Powys local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 36.8% inflationary increase is applied to the most recent sale price for BRIALLU of £208,000 on 19th June 2018. For the value to have increased from £208,000 to £284,441 over the eight years and one month to May 2026, the following assumptions must hold true:

  • The value of BRIALLU has moved in line with the HPI for detached houses in the Powys local authority area.
  • The June 2018 sale price of £208,000 represented a fair market value for the property.
  • The size, condition, and specification of BRIALLU has not materially changed since June 2018.
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.
