This is a sketch, not an offer. Every figure above is an assumption you set yourself. It ignores land value, finance, approvals, professional fees, taxes, marketing, contingency and the phasing of cash flow — all of which move real outcomes significantly. Actual partnership terms depend on the specific property and are agreed in writing. Use this to frame a conversation, not to make a commitment.
