About Gianni

I’m Gianni Mauro, a driven real estate professional who became licensed at just 18 years old, making me one of the youngest licensed real estate agents in the country at the time. Since entering the industry, I’ve built experience across residential real estate, multifamily investing, investment property analysis, zoning research, underwriting, fix-and-flip projects, and off-market acquisitions. Over the course of my career, I’ve worked with industry-leading brokerages including Keller Williams and Citypoint, where I developed a strong foundation in real estate sales, investment strategy, market analysis, and deal structuring. My experience includes working on multifamily real estate transactions involving 11-unit and 13-unit apartment buildings, while also actively pursuing my own real estate investment projects and fix-and-flip opportunities. I specialize in helping buyers, sellers, and real estate investors identify high-potential opportunities in residential and multifamily real estate. My background in underwriting, zoning analysis, value-add properties, and investment strategy allows me to approach every deal with an investor mindset focused on maximizing value and long-term growth. Whether you’re looking to buy a home, sell property, invest in multifamily real estate, analyze cash-flow opportunities, or explore value-add and redevelopment potential, I bring hands-on experience, strong market knowledge, and a results-driven approach to every transaction. My focus is simple: build long-term relationships, create opportunities, and help clients make confident, informed real estate decisions in today’s competitive market.
