18 BELMONT STREET Price Paid vs. HPI Average

The below graph shows the average detached house price in the Portsmouth local authority area over time, sourced from the HPI. The four 18 BELMONT STREET sales between March 1998 and August 2019 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 July 2013 sale was for 23% above the HPI. So the extrapolation line tracks at 23% above the HPI over time, until the August 2019 sale, where it falls to 8% above the HPI. The line then continues to track at 8% above the HPI.

What might 18 BELMONT STREET be worth now?

18 BELMONT STREET might now be worth an estimated £556,201.

This is based on house price inflation of 19.6%, between August 2019 and February 2025, for detached houses, in the Portsmouth local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 19.6% inflationary increase is applied to the most recent sale price for 18 BELMONT STREET of £465,000 on 9th August 2019. For the value to have increased from £465,000 to £556,201 over the six years and six months to February 2025, the following assumptions must hold true:

  • The value of 18 BELMONT STREET has moved in line with the HPI for detached houses in the Portsmouth local authority area.
  • The August 2019 sale price of £465,000 represented a fair market value for the property.
  • The size, condition, and specification of 18 BELMONT STREET has not materially changed since August 2019.
Disclaimer: Please note that this is a theoretical estimate based on assumptions which may or may not be correct. It should not be relied on for any purpose.
