How the MLS Works

The MLS is a private database maintained by local real estate associations. Only licensed real estate agents can add listings or access the full MLS. When a listing agent enters a property, it automatically distributes to major real estate websites through syndication. The MLS contains detailed property data, listing history, price changes, and status updates that consumer sites often lag behind on.

Why MLS Is More Accurate Than Zillow

Zillow and other consumer sites rely on MLS data but often have delays and inaccuracies. A home that is under contract on the MLS may still show as active on Zillow for days. Sold data, price changes, and days on market are more reliable on the MLS. Zillow's Zestimate is an algorithm, not an expert valuation. The MLS gives you the actual list price, actual sold price, and actual days on market from real transactions.

How Buyers Benefit

Your agent can set up an MLS search that updates in real time, sending you new listings that match your criteria. This ensures you see homes the moment they hit the market, not hours or days later when they appear on consumer sites. In competitive markets, that early access can make the difference between getting the home and missing out.

How Sellers Benefit

Listing on the MLS gives your home maximum exposure to every buyer's agent and their clients. Your listing automatically appears on hundreds of websites through syndication. The MLS also tracks showing activity and feedback, giving you valuable data about buyer interest.

MLS vs Zillow vs Redfin

Zillow and Redfin are consumer-facing websites that pull data from the MLS. They are useful for browsing, but they are not the source of truth. The MLS is the authoritative database. If you see a discrepancy between the MLS and a consumer site, the MLS is correct.
