6C MERTHYR STREET Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The two 6C MERTHYR STREET sales from March 2000 and July 2023 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 2000 sale was for 37% below the HPI. So the extrapolation line tracks at 37% below the HPI over time, until the July 2023 sale, where it falls to 48% below the HPI. The line then continues to track at 48% below the HPI.

What might 6C MERTHYR STREET be worth now?

This is based on house price inflation of 4.5%, between July 2023 and February 2025, for detached houses, in the Cardiff local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 4.5% inflationary increase is applied to the most recent sale price for 6C MERTHYR STREET of £260,000 on 17th July 2023. For the value to have increased from £260,000 to £271,735 over the two years and five months to February 2025, the following assumptions must hold true:

• The July 2023 sale price of £260,000 represented a fair market value for the property.
