The below graph shows the average detached house price in the East Riding of Yorkshire local authority area over time, sourced from the HPI. The two 21 HALLGATE sales from February 2024 and October 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 February 2024 sale was for 19% below the HPI. So the extrapolation line tracks at 19% below the HPI over time, until the October 2025 sale, where it rises to 33% above the HPI. The line then continues to track at 33% above the HPI.

21 HALLGATE might now be worth an estimated £282,793.
This is based on house price inflation of 1%, between October 2025 and April 2026, for semi-detached houses, in the East Riding of Yorkshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 1% inflationary increase is applied to the most recent sale price for 21 HALLGATE of £280,000 on 24th October 2025. For the value to have increased from £280,000 to £282,793 over the one year and six months to April 2026, the following assumptions must hold true:
