Demand for luxury apartment living in Miami Beach continues as relocations to South Florida for business don’t show signs of slowing down.

A partnership between Mast Capital, a real estate development and investment firm, and Boston-based real estate equity firm Rockpoint will help ease some of that demand in the next few years. Last November, the partnership secured a $64 million construction loan from PNC Bank to build a luxury multifamily development on Alton Road in Miami Beach.
