9 CROSSBY CLOSE Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the Brentwood local authority area over time, sourced from the HPI. The two 9 CROSSBY CLOSE sales from March 2015 and January 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 2015 sale was for 17% below the HPI. So the extrapolation line tracks at 17% below the HPI over time, until the January 2025 sale, where it rises to 7% below the HPI. The line then continues to track at 7% below the HPI.

What might 9 CROSSBY CLOSE be worth now?

The 5.6% inflationary increase is applied to the most recent sale price for 9 CROSSBY CLOSE of £490,000 on 21st January 2025. For the value to have increased from £490,000 to £517,359 over the nine months to April 2026, the following assumptions must hold true:

• The value of 9 CROSSBY CLOSE has moved in line with the HPI for semi-detached houses in the Brentwood local authority area.
