When the building has been let fully or to the planned occupancy level, the trader developer has completed the property development process except for closure by selling it on to a future landlord/investor and paying off the short term finance used for the development process. Upon sale the developer realises his profit, positive or negative, and moves on to the next property development.

Alternatively, for the permanent or temporary future the developer may choose other avenues of profitability but these are outwith the property development process. The point in time of sale can be any time the developer believes it propitious to do so either as above or earlier or later but the sale (or shadow value of the sale) at this point mark the end of the property development process.
