BAGLAN HOUSE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Rhondda Cynon Taf local authority area over time, sourced from the HPI. The three BAGLAN HOUSE sales between June 2000 and February 2008 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 December 2006 sale was for 50% below the HPI. So the extrapolation line tracks at 50% below the HPI over time, until the February 2008 sale, where it rises to 13% above the HPI. The line then continues to track at 13% above the HPI.

What might BAGLAN HOUSE be worth now?

BAGLAN HOUSE might now be worth an estimated £193,962.

This is based on house price inflation of 64.4%, between February 2008 and July 2025, for semi-detached houses, in the Rhondda Cynon Taf local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 64.4% inflationary increase is applied to the most recent sale price for BAGLAN HOUSE of £118,000 on 8th February 2008. For the value to have increased from £118,000 to £193,962 over the sixteen years and seven months to July 2025, the following assumptions must hold true:

• The value of BAGLAN HOUSE has moved in line with the HPI for semi-detached houses in the Rhondda Cynon Taf local authority area.
• The February 2008 sale price of £118,000 represented a fair market value for the property.
• The size, condition, and specification of BAGLAN HOUSE has not materially changed since February 2008.
