Your seller's closing statement (typically a Closing Disclosure or settlement statement) lists every line item between sale price and your wire-out amount. The big seller-side categories: listing-side commission (negotiated up front), buyer-broker compensation (if offered), state and local transfer/conveyance/recordation tax, title insurance owner's policy (in many states), recording fees, prorated property tax, prorated HOA dues, mortgage payoff plus per-diem interest, and miscellaneous closing fees. Review the statement carefully 24+ hours before closing — line-item errors are common and fixable then but harder to fix after funding. Out-of-state seller?
