Your estimated net proceeds equal the sale price minus mortgage balances, commissions, agreed buyer concessions, repairs, title and escrow charges, taxes, HOA-related fees, and other transaction expenses. The final amount can also be affected by prorations, liens, solar obligations, or costs associated with preparing the home.
I prepare a preliminary net sheet using the expected sale price and known expenses, then update it as the terms become clearer. This allows you to compare offers based on their likely net result, not just the headline price.
