The below graph shows the average terraced house price in the East Hertfordshire local authority area over time, sourced from the HPI. The three 77 PORT VALE sales between February 1999 and July 2009 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 2003 sale was for 4% above the HPI. So the extrapolation line tracks at 4% above the HPI over time, until the July 2009 sale, where it rises to 9% above the HPI. The line then continues to track at 9% above the HPI.

77 PORT VALE might now be worth an estimated £435,212.
This is based on house price inflation of 87.6%, between July 2009 and July 2025, for terraced houses, in the East Hertfordshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 87.6% inflationary increase is applied to the most recent sale price for 77 PORT VALE of £232,000 on 31st July 2009. For the value to have increased from £232,000 to £435,212 over the sixteen years to July 2025, the following assumptions must hold true:
