For every investment plot in the catalogue we publish the margin calculation. The formula is simple: forecast value minus purchase price and development cost.
The margin rate is the margin divided by total investment. A plot at 60m ֏ with 95m ֏ of development cost and a 215m ֏ forecast value yields a 60m ֏ margin, or 38.7%.
Forecast value is the most sensitive input. That is why every plot comes with a business plan setting out the assumptions — occupancy, prices, timelines — so you can check them and push back.
