MILLFIELD HOUSE 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 three MILLFIELD HOUSE sales between September 2008 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 November 2011 sale was for 258% above the HPI. So the extrapolation line tracks at 258% above the HPI over time, until the July 2022 sale, where it falls to 163% above the HPI. The line then continues to track at 163% above the HPI.

What might MILLFIELD HOUSE be worth now?

MILLFIELD HOUSE might now be worth an estimated £1,015,414.

This is based on house price inflation of 3.1%, between July 2022 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 3.1% inflationary increase is applied to the most recent sale price for MILLFIELD HOUSE of £985,000 on 8th July 2022. For the value to have increased from £985,000 to £1,015,414 over the one year and seven months to December 2024, the following assumptions must hold true:
