The exit is decided at underwriting, not at listing. By the time a property is for sale, every important decision has already been made: what it cost, what it is, who it's for, and what the market will call it. The listing just announces the results.
So the exit gets designed on day one, next to the land price. Sell on completion, or lease up and operate? The two answers produce different buildings. Different finishes, different unit mixes, different financing, different tolerance for schedule. A project built without that answer is built for nobody in particular, and the market prices "nobody in particular" accurately.
Holding the disposition in-house closes the loop. When the same operation that underwrote the deal also runs the sale or the lease-up, the feedback is direct: what buyers actually paid, what tenants actually signed, how long the market actually took. Those numbers walk straight back into the next underwriting. A developer who hands the exit to a stranger pays a fee and also loses the lesson.
And when the answer is operate: tenants found, spaces filled, income underwritten like any other line, in both directions. The building either earns its keep on paper before the land closes, or the land doesn't close.
