18 GOODWOOD AVENUE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The four 18 GOODWOOD AVENUE sales between July 1999 and September 2020 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 May 2016 sale was for 4% above the HPI. So the extrapolation line tracks at 4% above the HPI over time, until the September 2020 sale, where it falls to 1% above the HPI. The line then continues to track at 1% above the HPI.

What might 18 GOODWOOD AVENUE be worth now?

The 21.2% inflationary increase is applied to the most recent sale price for 18 GOODWOOD AVENUE of £235,000 on 11th September 2020. For the value to have increased from £235,000 to £284,925 over the three years and nine months to December 2024, the following assumptions must hold true:
