An estate sale, estate auction or tag sale is an efficient way to break up a household. An estate liquidation company runs the sale in exchange for a percentage of the proceeds. Depending on the area of the country and the number of items in the house, the commission may range from 25% to 45% of sales proceeds. The contents of the house are often being sold because the owner died, but sometimes the owner is simply downsizing and looking to start over with new things.
