1 MIDDLEFIELD Price Paid vs. HPI Average

The below graph shows the average detached house price in the Welwyn Hatfield local authority area over time, sourced from the HPI. The two 1 MIDDLEFIELD sales from August 1999 and March 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 August 1999 sale was for 48% below the HPI. So the extrapolation line tracks at 48% below the HPI over time, until the March 2018 sale, where it falls to 52% below the HPI. The line then continues to track at 52% below the HPI.

What might 1 MIDDLEFIELD be worth now?

1 MIDDLEFIELD might now be worth an estimated £450,026.

This is based on house price inflation of 10.4%, between March 2018 and March 2025, for detached houses, in the Welwyn Hatfield local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 10.4% inflationary increase is applied to the most recent sale price for 1 MIDDLEFIELD of £407,500 on 12th March 2018. For the value to have increased from £407,500 to £450,026 over the seven years to March 2025, the following assumptions must hold true:

  • The value of 1 MIDDLEFIELD has moved in line with the HPI for detached houses in the Welwyn Hatfield local authority area.
  • The March 2018 sale price of £407,500 represented a fair market value for the property.
  • The size, condition, and specification of 1 MIDDLEFIELD has not materially changed since March 2018.
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.
