21 PENTWYN TERRACE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Newport local authority area over time, sourced from the HPI. The three 21 PENTWYN TERRACE sales between November 2002 and September 2014 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 2007 sale was for 36% below the HPI. So the extrapolation line tracks at 36% below the HPI over time, until the September 2014 sale, where it rises to 36% above the HPI. The line then continues to track at 36% above the HPI.

What might 21 PENTWYN TERRACE be worth now?

This is based on house price inflation of 80.4%, between September 2014 and May 2026, for terraced 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 80.4% inflationary increase is applied to the most recent sale price for 21 PENTWYN TERRACE of £145,000 on 26th September 2014. For the value to have increased from £145,000 to £261,623 over the twelve years and four months to May 2026, the following assumptions must hold true:
