The below graph shows the average detached house price in the Pembrokeshire local authority area over time, sourced from the HPI. The two BLACK TAR HILL COTTAGE sales from August 2011 and July 2022 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 August 2011 sale was for 47% below the HPI. So the extrapolation line tracks at 47% below the HPI over time, until the July 2022 sale, where it rises to 1% above the HPI. The line then continues to track at 1% above the HPI.
BLACK TAR HILL COTTAGE might now be worth an estimated £321,522.
This is based on house price deflation of 1.1%, between July 2022 and December 2024, for detached houses, in the Pembrokeshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 1.1% deflationary decrease is applied to the most recent sale price for BLACK TAR HILL COTTAGE of £325,000 on 18th July 2022. For the value to have decreased from £325,000 to £321,522 over the one year and seven months to December 2024, the following assumptions must hold true:
