17 SIR BRIGGS AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Newport local authority area over time, sourced from the HPI. The two 17 SIR BRIGGS AVENUE sales from June 2015 and May 2021 have been plotted on the graph.

For example, the June 2015 sale was for 28% above the HPI. So the extrapolation line tracks at 28% above the HPI over time, until the May 2021 sale, where it falls to 3% below the HPI. The line then continues to track at 3% below the HPI.

What might 17 SIR BRIGGS AVENUE be worth now?
