Say you want to forego the full services of a broker and pay only to list your home on a multiple-listing service (MLS). That could cost about $100 to $500 depending on the level of service you receive. Some realtors offer MLS listing alone for a flat fee, with additional services available a la carte. MLS listing services can be obtained online. Unless you already have a buyer lined up, you need an MLS listing to alert potential buyers and their agents that your home is for sale.
