Specialists in income properties in CA, KY, TN & FL



At MultiUnitSeller.com, we believe successful income property marketing goes far beyond simply placing a listing on the market. The most qualified buyers are often the investors who already own and actively acquire income-producing real estate.
That's why we've generate and built two unique powerful platforms designed to connect sellers directly with targeted investors across California, Kentucky, Tennessee, and Florida.
Over the years, we've developed an exclusive 10,000+ opt-in email database of investors, property owners, past clients, acquisition partners, and industry professionals who want to be notified when new opportunities become available.
These are active buyers seeking multifamily properties, income-producing assets, and development opportunities—allowing us to place listings directly in front of investors already looking for their next acquisition.
One of our greatest strengths is a continuously growing database of nearly 14,000 income property owners across four states.
Built through years of research, advanced mapping technology, public records analysis, and ownership tracking, this database identifies multifamily and income property owners, along with the LLCs, corporations, partnerships, and individuals behind them.
Simply put, we market income properties directly to people who already own income properties.
We created MultiUnitSeller.com to bridge the gap between sellers and serious investors. Rather than relying solely on traditional marketing methods, we combine proprietary ownership data, investor relationships, and targeted outreach to maximize exposure for every listing.
Our database continues to grow as new ownership information is researched and verified, creating a unique marketing advantage built on years of industry knowledge and data collection.
The result is simple: better exposure, more qualified buyers, and stronger opportunities for both sellers and investors.
Mario John Gattavara is an Italian-American real estate broker born and raised in California's Napa Valley. Following his service in the United States Navy, Mario entered the real estate industry and quickly established himself as a top-producing sales agent through innovative marketing strategies, relentless work ethic, and an unwavering commitment to client success.
Over more than 20 years in the business, Mario has built a reputation for thinking differently. Rather than following traditional real estate practices, he continually develops creative marketing strategies and unique solutions designed to help clients maximize value and achieve exceptional results.
Licensed in California, Kentucky, Tennessee, and Florida, Mario specializes in income-producing real estate, multifamily properties, apartment complexes, investment opportunities, development land, and strategic land acquisitions. His experience spans everything from smaller income properties and fourplexes to larger apartment communities and complex development projects.
Having successfully closed nearly 2,000 transactional sides throughout his career, many involving unique challenges and complicated circumstances, Mario brings a depth of knowledge and real-world experience that only comes from decades of hands-on problem solving and negotiation.
Known for going the extra mile, Mario is actively pursuing additional licensure in Georgia, Ohio, and Virginia as part of his commitment to expanding opportunities and serving clients across a broader geographic footprint.
While there are plenty of agents in the marketplace, few invest the time, research, marketing systems, and industry relationships necessary to truly elevate the client experience.
For Mario, real estate is about more than simply selling property—it's about creating opportunities, solving problems, and delivering results.
