18 GYMNASIUM STREET Price Paid vs. HPI Average

The below graph shows the average detached house price in the Ipswich local authority area over time, sourced from the HPI. The six 18 GYMNASIUM STREET sales between November 1995 and June 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 September 2016 sale was for 16% above the HPI. So the extrapolation line tracks at 16% above the HPI over time, until the June 2020 sale, where it falls to 2% below the HPI. The line then continues to track at 2% below the HPI.

What might 18 GYMNASIUM STREET be worth now?

This is based on house price inflation of 12.7%, between June 2020 and December 2024, for detached houses, in the Ipswich local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 12.7% inflationary increase is applied to the most recent sale price for 18 GYMNASIUM STREET of £343,000 on 11th June 2020. For the value to have increased from £343,000 to £386,630 over the three years and six months to December 2024, the following assumptions must hold true:
