Nearly a dozen women are expected to make victim statements on Tuesday at the New York sentencing of twins Oren and Alon Alexander, 39, and Tal Alexander, 40, who were convicted in March.
Prosecutors have asked US District Judge Valerie E Caproni to give them life prison sentences. The brothers' lawyers have asked for the minimum of 15 years.
Oren and Tal Alexander were once nicknamed real estate's "A Team" for their ultra high-end sales and celebrity clientele.
After smashing sales records at industry powerhouse Douglas Elliman, the brothers started their own firm. Alon Alexander ran their family's private security company.
The brothers projected an exclusive lifestyle of yachts, private jets and waterfront mansions in Miami, but prosecutors said they began sexually assaulting women as early as 2001 or 2002, when they were in high school, and over time developed a pattern of drugging and raping women who they enticed to join them on luxury getaways.
At least 70 women were raped or sexually assaulted by the men, prosecutors said in a court filing that called the brothers "serial rapists".
Defence lawyers said the brothers apologise to the women they insulted or offended for conduct they admit was "insensitive toward the feelings of certain women at certain times".
They also maintained their innocence.
The trio were arrested in 2024 and have been held without bail ever since.
The judge, Caproni, has said she believes the brothers should not be incarcerated at the same prison because they were a bad influence on one another. The brothers' lawyers plan to argue that they belong together, even behind bars.
