18 UNWIN GREEN 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 18 UNWIN GREEN sales from January 2007 and May 2013 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 January 2007 sale was for 27% below the HPI. So the extrapolation line tracks at 27% below the HPI over time, until the May 2013 sale, where it rises to 23% below the HPI. The line then continues to track at 23% below the HPI.

What might 18 UNWIN GREEN be worth now?

18 UNWIN GREEN might now be worth an estimated £146,423.

This is based on house price inflation of 76.4%, between May 2013 and June 2025, 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 76.4% inflationary increase is applied to the most recent sale price for 18 UNWIN GREEN of £83,000 on 15th May 2013. For the value to have increased from £83,000 to £146,423 over the eleven years and eleven months to June 2025, the following assumptions must hold true:

• The value of 18 UNWIN GREEN has moved in line with the HPI for terraced houses in the South Kesteven local authority area.
• The May 2013 sale price of £83,000 represented a fair market value for the property.
