20 PORTMAN CLOSE Price Paid vs. HPI Average

The below graph shows the average detached house price in the North Hertfordshire local authority area over time, sourced from the HPI. The three 20 PORTMAN CLOSE sales between June 1996 and January 2018 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 2012 sale was for 42% below the HPI. So the extrapolation line tracks at 42% below the HPI over time, until the January 2018 sale, where it falls to 45% below the HPI. The line then continues to track at 45% below the HPI.

What might 20 PORTMAN CLOSE be worth now?

This is based on house price inflation of 17.4%, between January 2018 and December 2024, for detached houses, in the North Hertfordshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 17.4% inflationary increase is applied to the most recent sale price for 20 PORTMAN CLOSE of £370,000 on 19th January 2018. For the value to have increased from £370,000 to £434,420 over the five years and one month to December 2024, the following assumptions must hold true:

• The value of 20 PORTMAN CLOSE has moved in line with the HPI for detached houses in the North Hertfordshire local authority area.
• The January 2018 sale price of £370,000 represented a fair market value for the property.
