Before a sign goes up, write down what you know: your timing, mortgage or lien payoff, preparation questions, and any costs you expect. That makes the conversation with your agent, lender, and closing professional more specific.
Separate the estimate from the final statement.
A net-sheet estimate can help you organize the questions. It cannot replace payoff quotes, attorney charges, tax prorations, HOA information, negotiated credits, or a final closing statement. Use real figures as they become available.
Compare the whole move.
Sale price is one part of an offer. Financing, contingencies, closing dates, possession, repairs, and your next-home plan can matter too. A clearer list helps you decide what needs attention first.
