Part 1 of 4

Why a seller cares

It is where agents find homes for their buyers and where the portals pull their listings from. Getting on it generally takes a member; flat-fee brokers offer that entry without the rest of the service.

Part 2 of 4

A simple example

A seller without an agent pays a flat fee to have the home entered on the MLS. It appears on the big portals within a day; everything else about the sale is still theirs to do.

Multiple listing service: a simple example
How the home reaches the MLSWhat it costs, roughly
A full-service listing agentA percentage of the price, for the whole job
A flat-fee MLS brokerA few hundred dollars, for the entry alone
Not on the MLSNothing, and the portals and most buyers' agents never see it

The MLS is the distribution. Everything else about selling is separate from it.

Part 3 of 4

What people get wrong

That the portals are the market. They are copies of the MLS, and a home not on the MLS is on none of them.

What a definition is, and what it isn't

Keighbor is a software company, not a law firm, brokerage, or tax adviser. This is general information, not legal, tax, financial, or real estate advice about your sale. Your situation may differ. Before acting on a contract, disclosure, title, tax, or pricing question, ask an appropriately licensed professional in your state.
