Over 50% of the municipality's revenue is provided by density sales/ citizens pay for it.
Reza Alizadeh, housing researcher:
The municipality provides more than 50% of its revenue from the point of sale of density; The income is immediately deposited into the municipality's account, but in the medium and long term the citizens pay for it by reducing the quality of life and exerting pressure on municipal infrastructure.
This immediate benefit encourages the municipality to sell more density and limit the supply of land within the city limits; Because by building more densely on existing land, it makes more money. This cycle also increases the potential value of the land and its price.
