How to Use the Preconstruction Condo Assignment Profit Calculator
A preconstruction condo assignment lets a buyer sell their purchase contract to another buyer before the building is completed, without ever closing on the unit themselves. The profit comes from the difference between the assignment fee you paid to acquire the contract and the assignment fee you receive when you sell it — this calculator takes the original contract price, both fees, and your tax rate to estimate your pre-tax and after-tax profit.
Your pre-tax profit is simply the fee you received minus the fee you paid. In a cooling market, it's possible to receive less than what you originally paid — a negative assignment fee — and this calculator handles that case by accepting negative values for either field.
Assignment profit is generally taxed as a capital gain, and the rate depends on how long you held the contract, your income bracket, and whether it qualifies for short-term or long-term treatment. Assignment contracts are also common mainly in a handful of markets like Florida and New York, and many developer contracts restrict or prohibit assignment altogether — so always confirm both the tax treatment and whether assignment is even permitted before relying on this estimate.
