What is co-broker in real estate?

In most cases, a co-broker works with the listing brokerage to help sell the property. The co-broker (or selling broker as they are commonly referred) will usually bring the buyer, and the listing broker will work the seller to help complete the transaction. The listing broker will split the commission with the co-broker for providing the buyer. This enables real estate firms to sell each other's listings, thus enabling many more transactions to take place, making it easier and faster to find buyers for properties. It also enables buyers to only be required to work with one agent at one company instead of having to find an agent at each company.
