25 SINCLAIR CLOSE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Boston local authority area over time, sourced from the HPI. The two 25 SINCLAIR CLOSE sales from May 2023 and February 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 May 2023 sale was for 12% above the HPI. So the extrapolation line tracks at 12% above the HPI over time, until the February 2025 sale, where it rises to 26% above the HPI. The line then continues to track at 26% above the HPI.

What might 25 SINCLAIR CLOSE be worth now?

This is based on house price inflation of 7.6%, between February 2025 and April 2026, for semi-detached houses, in the Boston local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 7.6% inflationary increase is applied to the most recent sale price for 25 SINCLAIR CLOSE of £200,000 on 21st February 2025. For the value to have increased from £200,000 to £215,152 over the ten months to April 2026, the following assumptions must hold true:
