NASSI Investment & Management Group helps owners and investors acquire, protect, and grow the value of their real estate across Southern California — combining disciplined investment strategy with full-service, white-glove property management.
Founded in 2011 and headquartered in the heart of Beverly Hills, NASSI Investment & Management Group is a boutique real estate investment and property management firm serving private owners, families, and individual investors throughout Southern California.
We operate on a simple principle: your property should be treated with the same care, discipline, and attention to detail as our own. Whether you are acquiring your first investment property, investing passively alongside us, or overseeing a growing portfolio, our team pairs sophisticated investment insight with hands-on, responsive management.
From apartments and multifamily to commercial real estate and single-family rental homes — plus private syndications for individual investors — we deliver a level of service designed to preserve capital, maximize income, and give owners genuine peace of mind.
Speak With Our TeamWe combine the analytical rigor of an investment firm with the day-to-day excellence of a premier property management company — across every major asset class.
Full-cycle management of apartment communities and multifamily buildings — leasing, rent collection, maintenance, and reporting engineered to reduce vacancy and grow net operating income.
Structured opportunities that let individuals invest alongside us in commercial and residential real estate — access to institutional-quality deals without the burdens of direct, hands-on ownership.
Proactive management and leasing for retail, office, and mixed-use assets — keeping your commercial property attractive, well-maintained, and positioned for long-term tenants.
Boutique, attentive management for single-family homes and condominiums, delivering the same institutional-grade service and care to individual owners as to large portfolios.
Sourcing, underwriting, and acquisition support for owners looking to expand — with market analysis and strategy grounded in decades of Southern California experience.
Ongoing advisory to reposition, improve, and optimize your holdings — from value-add improvements to hold-versus-sell analysis that protects and compounds your capital.
Great returns are made at the point of purchase. Our team helps investors identify well-positioned opportunities, underwrite them with discipline, and move decisively in a competitive market. We evaluate income potential, condition, location, and risk so you can invest with clarity and confidence rather than guesswork.
Once a property is in your portfolio, we identify the improvements, lease strategies, and operational efficiencies that raise rents and increase value. From cost-effective upgrades to smarter tenant mix, our recommendations are always measured against a single question: does this improve your long-term return?
As your holdings grow, so does complexity. We provide ongoing guidance on hold-versus-sell decisions, refinancing timing, and market trends — helping you make informed choices at every stage of ownership. You gain an experienced partner who thinks like an owner because we manage like one.
For qualified individuals who want the returns of real estate without the demands of ownership, NASSI opens select opportunities to invest directly alongside our team. Through private syndications, you gain fractional ownership in carefully chosen commercial and residential properties — professionally sourced, financed, and managed from acquisition to exit.
Pool your capital with ours to own institutional-quality retail, office, and mixed-use assets. We handle underwriting, acquisition, and management while you receive proportional income and appreciation.
Participate in apartment and multifamily investments across Southern California — value-add and stabilized opportunities structured to generate reliable cash flow and long-term equity growth.
You invest; we do the work. Enjoy transparent reporting, aligned interests, and a seasoned Beverly Hills team managing every property as diligently as we manage our own capital.
Comprehensive, full-service property management designed to save you time, reduce risk, and maximize the income from every property you own.
We aggressively market vacant units through premium online and local channels to attract the largest possible pool of qualified, long-term tenants — filling vacancies faster and protecting your cash flow.
A rigorous screening process including employment and income verification, credit review, and reference checks ensures we place reliable, high-quality residents who care for your property.
We collect rent in full and on time, handle late payments and disputes professionally, and manage any required legal action — so you receive your funds without the friction.
Around-the-clock repair response, routine property inspections, and coordination with vetted, licensed contractors keep your asset in excellent condition and your residents satisfied.
Detailed, transparent monthly financial statements — accessible anytime through your owner portal — give you a precise picture of income and expenses for every property you own.
Our team is available seven days a week to respond to owners and residents, backed by an online concierge for maintenance requests, payments, and account access at any hour.
