An agent's niche is not what they say about themselves. It is the short sentence other people use to describe them at dinner. "She does waterfront." "He works estate sales." "She is the architectural-home person in the area." That sentence is the entire engine of niche marketing.

If no one is saying a specific sentence about you yet, the niche is still in your head and has not become an asset.

The best niche is not the most prestigious one. It is the smallest defensible one you can plausibly be among the top three agents in within a year. Property type. Neighborhood. Buyer profile. Price band. Transaction type. Niche options are wider than most agents think.

Pick the niche where your existing experience already has a head start. That is the niche where the early wins arrive.

Three assets are enough to begin. A market read for the niche. A short, written point of view about how listings in the niche should be prepared. A single case study from a recent or upcoming engagement. With those three, the niche has a visible shape. Without them, the niche is a costume.

Add a fourth and a fifth asset only after the first three are real and refreshed quarterly.

The first sign of niche traction is the urge to add a second niche. Resist it for at least a year. The first niche is still consolidating, and adding a second one too soon dilutes the sentence other people are starting to say about you. Win the first niche fully before expanding.

​One niche, fully won, produces more revenue than three niches half-built.

The interesting thing about niches is that they produce more business outside the niche than inside it. Sellers who hear that you are "the architectural-home person" trust you to handle their non-architectural sale too. The niche is the credential. The general business follows quietly.

​Build the niche on purpose. Let the rest follow on its own.
