The below graph shows the average terraced house price in the North Lincolnshire local authority area over time, sourced from the HPI. The three 20 PORTER STREET sales between October 2004 and October 2010 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 June 2005 sale was for 18% below the HPI. So the extrapolation line tracks at 18% below the HPI over time, until the October 2010 sale, where it falls to 26% below the HPI. The line then continues to track at 26% below the HPI.

20 PORTER STREET might now be worth an estimated £97,071.
This is based on house price inflation of 51.7%, between October 2010 and August 2025, for terraced houses, in the North Lincolnshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 51.7% inflationary increase is applied to the most recent sale price for 20 PORTER STREET of £64,000 on 15th October 2010. For the value to have increased from £64,000 to £97,071 over the fifteen years and two months to August 2025, the following assumptions must hold true:
