Give the others right because without the garden share you cannot achieve a high rent. Because anyone renting for 12€ per m2 and then can only look onto the large garden from their balcony will think twice about not rather moving into a semi-detached house with its own garden for the same rent. Especially during the pandemic, having your own garden has gained enormous importance. And the return with 3000€ per m2 in construction costs and high interest rates is also rather suboptimal. Even if the plot is already available, the factors mentioned above should also be taken into consideration.
