An estate sale is an auction or yard sale, usually held to liquidate a deceased person’s goods quickly. Estate sales are often a great place to source items to resell online for a profit. Many sellers find items that provide them with their most profitable sales yet when they scout estate sales.
However, as with all forms of product sourcing, you need to know whether the items you are buying are actually going to sell. This can be tricky because you often don't have access to market research software to give you the answers you need to decide whether to purchase items. In the end, your success with buying from estate sales will come with experience.
