23 CASTLEGATE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the South Kesteven local authority area over time, sourced from the HPI. The two 23 CASTLEGATE sales from July 1998 and September 2014 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 1998 sale was for 2% below the HPI. So the extrapolation line tracks at 2% below the HPI over time, until the September 2014 sale, where it falls to 37% below the HPI. The line then continues to track at 37% below the HPI.

What might 23 CASTLEGATE be worth now?

23 CASTLEGATE might now be worth an estimated £121,338.

This is based on house price inflation of 61.8%, between September 2014 and April 2026, for terraced houses, in the South Kesteven local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 61.8% inflationary increase is applied to the most recent sale price for 23 CASTLEGATE of £75,000 on 18th September 2014. For the value to have increased from £75,000 to £121,338 over the twelve years and five months to April 2026, the following assumptions must hold true:

• The value of 23 CASTLEGATE has moved in line with the HPI for terraced houses in the South Kesteven local authority area.
• The September 2014 sale price of £75,000 represented a fair market value for the property.
• The size, condition, and specification of 23 CASTLEGATE has not materially changed since September 2014.
