DERLWYN Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Powys local authority area over time, sourced from the HPI. The three DERLWYN sales between February 1998 and March 2017 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 January 2000 sale was for 19% below the HPI. So the extrapolation line tracks at 19% below the HPI over time, until the March 2017 sale, where it falls to 39% below the HPI. The line then continues to track at 39% below the HPI.

What might DERLWYN be worth now?

DERLWYN might now be worth an estimated £130,562.

This is based on house price inflation of 45.1%, between March 2017 and February 2025, for semi-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 45.1% inflationary increase is applied to the most recent sale price for DERLWYN of £90,000 on 9th March 2017. For the value to have increased from £90,000 to £130,562 over the eight years and one month to February 2025, the following assumptions must hold true:

• The value of DERLWYN has moved in line with the HPI for semi-detached houses in the Powys local authority area.
• The March 2017 sale price of £90,000 represented a fair market value for the property.
• The size, condition, and specification of DERLWYN has not materially changed since March 2017.
