16 PORTWAY GARDENS Price Paid vs. HPI Average

The below graph shows the average detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The four 16 PORTWAY GARDENS sales between June 2000 and May 2021 have been plotted on the graph.

For example, the December 2014 sale was for 43% above the HPI. So the extrapolation line tracks at 43% above the HPI over time, until the May 2021 sale, where it falls to 29% above the HPI.
