18 CONQUEST CLOSE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the North Hertfordshire local authority area over time, sourced from the HPI. The five 18 CONQUEST CLOSE sales between May 1998 and September 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 March 2021 sale was for 50% above the HPI. So the extrapolation line tracks at 50% above the HPI over time, until the September 2025 sale, where it falls to 44% above the HPI. The line then continues to track at 44% above the HPI.

What might 18 CONQUEST CLOSE be worth now?

This is based on house price inflation of 0.9%, between September 2025 and April 2026, for terraced houses, in the North Hertfordshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 0.9% inflationary increase is applied to the most recent sale price for 18 CONQUEST CLOSE of £540,000 on 10th September 2025. For the value to have increased from £540,000 to £544,661 over the one year and five months to April 2026, the following assumptions must hold true:
