An assignment sells your agreement to buy, not a finished home, so its value is not the price of the unit. It is what a buyer will pay to step into your agreement: your original price against today's, the deposits you have paid, how far away closing is, the builder's consent and fee, and the terms of your agreement of purchase and sale.
A verified agent who works assignments prepares a free assessment from those facts. No formula can.
Your purchase price against what the builder or the resale market asks today for the same unit. The deposits paid, which the buyer repays you. The time to occupancy and final closing. Whether the builder allows assignment, what it charges, and whether it lets you advertise. The clauses in your agreement about assignment, occupancy fees and adjustments.
Your agreement of purchase and sale, the deposit receipts, any amendments, the builder's assignment policy, and your target date. With those an agent can give you a range within a day or two.
