How do i list a home on the mls for free?

Brokerage

Interview a real estate broker or agent. Agree to allow them to list your home. They will place your home on the Multiple Listing Service (MLS) for free until the home is sold. Once the home is sold, you will owe them a commission for the sale.

Online

Look online for a flat fee brokerage that offers a deal for listings. Some online brokerages will list your home for free if you buy a home through them as well. This is a deal that can also be negotiated with some brokerages.
