21 PORTLOCK ROAD Price Paid vs. HPI Average

The below graph shows the average terraced house price in the Windsor and Maidenhead local authority area over time, sourced from the HPI. The five 21 PORTLOCK ROAD sales between August 1998 and February 2014 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 September 2006 sale was for 6% above the HPI. So the extrapolation line tracks at 6% above the HPI over time, until the February 2014 sale, where it falls to 5% above the HPI. The line then continues to track at 5% above the HPI.

What might 21 PORTLOCK ROAD be worth now?

This is based on house price inflation of 56.6%, between February 2014 and June 2025, for terraced houses, in the Windsor and Maidenhead local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 56.6% inflationary increase is applied to the most recent sale price for 21 PORTLOCK ROAD of £331,000 on 21st February 2014. For the value to have increased from £331,000 to £518,320 over the ten years and eight months to June 2025, the following assumptions must hold true:
