Trust, cooperation, and market information everyone can count on.

The Multiple Listing Service is a neutral place where real estate professionals collaborate based on shared rules and reliable data.

Being In The Know™ is better than being in the dark.

Imagine you're standing in a room and it's pitch black. You don't know the layout, where the doors or light switches are, or what objects are around that you might trip on.

Not so fun, right?

That's essentially what buying and selling homes would be like if we didn't have the Multiple Listing Service. The Multiple Listing Service turns the lights on, helping to create an open, fair and efficient marketplace.

Agents representing home sellers share those properties on the Multiple Listing Service. The Multiple Listing Service collects that information in a secure system governed by agreed upon rules and standards.

It is then used by many people, in many ways...

Sellers' agents use it to compare similar homes to their clients' so that they can give data-driven advice on when to list and for how much.
