As long as it is not built, a land can be freely negotiated and its value depends on the market and demand context.
Conversely, as soon as it is built it can no longer be sold separately.
The practice of wanting to compare the value of constructed land with the purchase prices of those not
is basically incorrect.
This error continues to be repeated, especially in relation to the real value method, inadequate to the purpose.
Remember: the built ground was “Consumed” and, since it is no longer building, is no longer subject to demand or has no value.
