Real Estate Investment Banking refers to a division or department within an investment bank that specializes in providing financial services and advice to real estate companies, property developers, and other clients involved in the commercial real estate industry. This includes activities such as raising capital through debt or equity offerings, advising on mergers and acquisitions, and assisting with the sale or purchase of properties. Investment banks that provide these services typically have a team of experts who specialize in various aspects of real estate finance, including structured finance, commercial mortgage-backed securities (CMBS), and real estate private equity.
