Diaz Multifamily Group

Diaz Multifamily Group is part of Marcus & Millichap’s National Multi-Housing Group, focused exclusively on apartment sales across the Inland Empire and Greater Los Angeles. We help private owners make informed decisions about when to sell, how to exchange, and what comes next.
By combining local market knowledge with the national reach of the Marcus & Millichap platform, we bring more qualified buyers to the table — helping owners secure stronger pricing, faster closings, and better terms. From family trusts and longtime landlords to exchange-driven investors, we tailor each strategy to fit your financial goals and timing.

If you’re thinking about selling, we’ll show you what it’s worth, what your options are, and how to make the most of your next move.
