18 NELSON STREET Price Paid vs. HPI Average

The below graph shows the average detached house price in the South Oxfordshire local authority area over time, sourced from the HPI. The three 18 NELSON STREET sales between September 1998 and April 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 November 2003 sale was for 38% above the HPI. So the extrapolation line tracks at 38% above the HPI over time, until the April 2018 sale, where it falls to 16% above the HPI. The line then continues to track at 16% above the HPI.

What might 18 NELSON STREET be worth now?

18 NELSON STREET might now be worth an estimated £914,850.

This is based on house price inflation of 24.5%, between April 2018 and December 2024, for detached houses, in the South Oxfordshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 24.5% inflationary increase is applied to the most recent sale price for 18 NELSON STREET of £735,000 on 19th April 2018. For the value to have increased from £735,000 to £914,850 over the five years and four months to December 2024, the following assumptions must hold true:

• The value of 18 NELSON STREET has moved in line with the HPI for detached houses in the South Oxfordshire local authority area.
• The April 2018 sale price of £735,000 represented a fair market value for the property.
