TY BYCHAN 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 TY BYCHAN sales from November 2013 and October 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 November 2013 sale was for 58% below the HPI. So the extrapolation line tracks at 58% below the HPI over time, until the October 2023 sale, where it falls to 64% below the HPI. The line then continues to track at 64% below the HPI.

What might TY BYCHAN be worth now?

TY BYCHAN might now be worth an estimated £185,058.

This is based on house price inflation of 2.8%, between October 2023 and June 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 2.8% inflationary increase is applied to the most recent sale price for TY BYCHAN of £180,000 on 24th October 2023. For the value to have increased from £180,000 to £185,058 over the two years and four months to June 2025, the following assumptions must hold true:

• The value of TY BYCHAN has moved in line with the HPI for detached houses in the Cardiff local authority area.
• The October 2023 sale price of £180,000 represented a fair market value for the property.
• The size, condition, and specification of TY BYCHAN has not materially changed since October 2023.
