18 TRINITY CIRCLE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Buckinghamshire local authority area over time, sourced from the HPI. The two 18 TRINITY CIRCLE sales from December 2019 and December 2025 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 December 2019 sale was for 3% below the HPI. So the extrapolation line tracks at 3% below the HPI over time, until the December 2025 sale, where it rises to 4% above the HPI. The line then continues to track at 4% above the HPI.

What might 18 TRINITY CIRCLE be worth now?

This is based on house price deflation of 1.6%, between December 2025 and April 2026, for detached houses, in the Buckinghamshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 1.6% deflationary decrease is applied to the most recent sale price for 18 TRINITY CIRCLE of £900,000 on 4th December 2025. For the value to have decreased from £900,000 to £885,952 over the one year and eight months to April 2026, the following assumptions must hold true:
