15 PORTMAN CRESCENT Price Paid vs. HPI Average

The below graph shows the average detached house price in the Bournemouth Christchurch and Poole local authority area over time, sourced from the HPI. The two 15 PORTMAN CRESCENT sales from November 1996 and January 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 November 1996 sale was for 66% above the HPI. So the extrapolation line tracks at 66% above the HPI over time, until the January 2018 sale, where it falls to 60% above the HPI. The line then continues to track at 60% above the HPI.

What might 15 PORTMAN CRESCENT be worth now?

This is based on house price inflation of 21.7%, between January 2018 and February 2025, for detached houses, in the Bournemouth Christchurch and Poole local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 21.7% inflationary increase is applied to the most recent sale price for 15 PORTMAN CRESCENT of £735,000 on 30th January 2018. For the value to have increased from £735,000 to £894,744 over the six years and eleven months to February 2025, the following assumptions must hold true:
