Top Realtors and Real Estate Agents in Stony Brook, NY

The best-matched agent depends on your property type, price point, and timeline, but EffectiveAgents currently ranks Lisa Jaeger at Douglas Elliman as the top-performing agent in Stony Brook, NY, with 832 career transactions and $410.7M in all-time sales volume. Our methodology analyzes verified outcomes across 158 local transactions, comparing sale-to-list performance, closing consistency, and review patterns rather than advertising. That data-driven approach helps you evaluate the 42 ranked agents against measurable results instead of name recognition.

Rankings are built from verified MLS transaction data. We analyze more than fifteen performance signals for every agent, including sales volume in your city and zip code, recent and all-time transactions, days on market, negotiation results, price-point fit, and verified reviews. Agents cannot pay for placement.

Our data covers 521 real estate agents serving the Stony Brook area. The count represents agents with transaction activity recorded in our Stony Brook market data, not simply everyone holding a license.

Stony Brook's median sale price is $814,592 as of July 2026. Half of recent sales closed above that figure and half below. It is a useful baseline for understanding the market, but an experienced local agent will price your home against comparable recent sales in your neighborhood, not the citywide median.

The median home in Stony Brook goes to contract in about 17 on the market, though that figure reflects a -6 days change compared with a year ago. Actual timelines vary widely: correctly priced homes in desirable zip codes like 11790 and 11794 often move faster, while listings that need a price correction (about 13.6% of the market saw drops) sit longer. Condition, pricing strategy, and season all matter. After an accepted offer, add roughly 30 to 60 days to close, depending on financing and inspection contingencies.

No. EffectiveAgents is free for home buyers and sellers, with no obligation to work with any agent we match you with.

No. Agents cannot pay for placement anywhere in these rankings. Positions are earned from verified transaction performance only.

Commissions are negotiable and vary by agent, service level, and transaction. There is no set rate, and recent industry changes have made commission structures more flexible than ever. Discuss the structure directly with your agent before signing a listing or buyer agreement.

The individual agent matters more than the brand on the sign. Offices within the same national franchise vary widely in performance, and the agent you hire, not the logo, prices your home, negotiates your contract, and manages your closing. A strong local agent brings firsthand knowledge of Stony Brook neighborhoods, pricing patterns, and buyer activity. Compare agents on verified local results such as recent sales, days on market, and negotiation outcomes rather than name recognition.

Ask how many homes they have closed in Stony Brook in the past year, what their average sale-to-list ratio is, and how much of their business is in your neighborhood and price range. Ask how they will market your home or find you listings, and how often they will communicate. Strong agents answer with specifics. Verified transaction data is the fastest way to confirm what you hear.
