Cindy Ambuehl, 51
The Agency, Los Angeles
Ambuehl helped spark a bidding war over the five-bedroom Santa Monica home of composer Jonathan Elias earlier this year. It went for $8.6 million -- about $500,000 more than asking. The property offers a Lakers-themed basketball court and a two-story guesthouse. Ambuehl has spent most of her career working with celebrities: first as an actor on such shows as Wings and Seinfeld, and now as their real estate agent.

Corcoran, New York
"Each deal is a different story," says Balan, a 20-year industry vet. The story behind 237 Lafayette St. involved 12-foot ceilings -- and caught the imagination of London-based Mumford & Sons guitarist Winston Marshall, who spent $3.2 million in June for a "massive, raw" loft space in the building, on the edge of SoHo.

Matt Breitenbach, 32
Douglas Elliman, Bridgehampton, N.Y.
Breitenbach has real estate bona fides that rival his more seasoned peers. His dad is a home builder on the East End of Long Island, and he spent childhood summers watching houses get framed. After college he joined forces with his mother, Susan Breitenbach, a Hamptons broker for Corcoran, and cultivated music-biz titans like Russell Simmons, whose East Hampton home recently sold for $6.995 million. Breitenbach jumped from Corcoran to Douglas Elliman's new sports and entertainment division -- with mom's blessing.
His personal abode: A "little oasis" on three acres north of Montauk Highway, which bisects the Hamptons.

"You can't live without music or a home," says Feder, whose former record-business career led her to real estate, with a focus on pied-a-terre homes and helping bicoastal music executives move East.

Ty Forkner, 38
South Beach International, Miami Beach
A saltwater lagoon filled with sharks and eels and a rooftop skate park are among the features of Lil Wayne's La Gorce Island home, now on the market for $18 million. The listing is with Forkner, who sold the rapper’s two-bedroom condo at Setai in South Beach in 2014 for $3.4 million. Forkner was fired from his first job as an agent “for being too ambitious,” he says. He has since done deals with acts including Drake and Pharrell Williams' protegee Teyana Taylor.

Rosina Seydel, 49
Beacham & Company, Atlanta
While marketing top-end homes (like a $6.3 million Buckhead mansion that was Atlanta's top residential deal of 2014), Seydel has found a lucrative niche in leasing luxury properties. Both Lil Wayne and Cee Lo Green have leased the Infinito penthouse in midtown Atlanta's Aqua condominium, a 4,176-square-foot residence with floor-to-ceiling windows, outdoor entertainment areas and state-of-the-art security.

Leonard Steinberg, 50
Compass Realty, New York
A fashion designer who entered real estate 20 years ago "out of curiosity" -- and to provide a level of service he says he found lacking -- Steinberg has built an A-list client roster.

Donna Summer sat down at a grand piano to sing octaves in the living room of a pre-Civil War home with 14-foot ceilings. Such are the tales Tisdale can tell after 38 years of selling Nashville real estate to big-name clients, from quirky label executives carrying guns to iconic artists (like the late Summer) testing the acoustics with impromptu performances. Tisdale offers the privacy stars crave: "I've sold dozens of farms to celebrities," she says.
Her personal abode: A hilltop contemporary with views of the Brentwood valley.
