Sellers generally pay 6% to 8% of the sale price in total transaction costs, with the bulk being the real estate commission. Other seller costs can include owner's title insurance if agreed in the contract, documentary stamp tax on the deed, HOA estoppel and payoff fees when applicable, prorated property taxes, and any outstanding liens or mortgage payoffs.
I provide both buyers and sellers with a net sheet early in the process so they can see an accurate breakdown before we are under contract.
