BLACKTOWN FARM Price Paid vs. HPI Average

The below graph shows the average detached house price in the Newport local authority area over time, sourced from the HPI. The two BLACKTOWN FARM sales from September 1996 and December 2018 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 September 1996 sale was for 169% above the HPI. So the extrapolation line tracks at 169% above the HPI over time, until the December 2018 sale, where it falls to 116% above the HPI. The line then continues to track at 116% above the HPI.

What might BLACKTOWN FARM be worth now?

BLACKTOWN FARM might now be worth an estimated £835,401.

This is based on house price inflation of 28.5%, between December 2018 and December 2024, for detached houses, in the Newport local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 28.5% inflationary increase is applied to the most recent sale price for BLACKTOWN FARM of £650,000 on 11th December 2018. For the value to have increased from £650,000 to £835,401 over the six years to December 2024, the following assumptions must hold true:

• The value of BLACKTOWN FARM has moved in line with the HPI for detached houses in the Newport local authority area.

• The size, condition, and specification of BLACKTOWN FARM has not materially changed since December 2018.
