161 ONGAR ROAD 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 161 ONGAR ROAD sales from April 1997 and June 2004 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 April 1997 sale was for 25% above the HPI. So the extrapolation line tracks at 25% above the HPI over time, until the June 2004 sale, where it rises to 28% above the HPI. The line then continues to track at 28% above the HPI.

What might 161 ONGAR ROAD be worth now?

This is based on house price inflation of 129.3%, between June 2004 and February 2025, for semi-detached houses, in the Brentwood local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 129.3% inflationary increase is applied to the most recent sale price for 161 ONGAR ROAD of £300,000 on 4th June 2004. For the value to have increased from £300,000 to £687,766 over the 21 years and four months to February 2025, the following assumptions must hold true:
