Why the Broker You Choose Matters More in NNN Than Any Other Asset Class
In residential real estate, a mediocre broker costs you time and maybe 0.5% on negotiation. In NNN, a mediocre broker can cost you the entire investment — through a lease with hidden landlord obligations, a below-market cap rate you didn't know to push back on, or a tenant credit problem that wasn't flagged before closing.
The NNN market looks simple from the outside. Passive income, corporate guarantee, no management. But the lease — the document that defines your obligations for the next 15–20 years — is extraordinarily technical. Co-tenancy clauses, kick-out provisions, landlord repair carve-outs, assignment restrictions, and subordination language are all standard fare in NNN leases, and none of them are friendly to uninformed buyers.
Here are the seven questions I'd ask any NNN broker before hiring them — and what the answers tell you.
1. Do you represent buyers exclusively, or do you also list NNN properties for sale?
This is the most important question. A broker who lists properties for sale and also represents buyers has an inherent conflict of interest. They are paid more when prices are higher (they represent sellers), and their relationships with listing brokers who owe them future deal flow can subtly influence which deals they present to you.
A broker who represents buyers only — no listings, no dual agency — has one motivation: finding you the best deal at the best price. That alignment matters enormously over a $2M–$8M transaction.
What to listen for: A specialist buyer's broker will say they represent buyers only. A generalist broker will hedge: "We mostly represent buyers but sometimes list properties too." That hedge is a conflict of interest disclosure.
2. What is your experience specifically with NNN leases — and can you review the lease yourself?
Most commercial real estate brokers are generalists. They cover office, industrial, multifamily, retail, and NNN — everything. Their NNN lease knowledge is a mile wide and an inch deep.
A NNN specialist has reviewed hundreds of triple net leases and knows exactly which clauses to scrutinize: absolute NNN vs. modified NNN, landlord repair obligations, roof and structure carve-outs, co-tenancy provisions, kick-out clauses, subletting restrictions, assignment on 1031 exchange, and SNDA (subordination, non-disturbance, and attornment) provisions.
Even better: some NNN specialists hold law licenses in addition to their broker license. That background means lease review is done with greater depth — co-tenancy clauses, landlord repair carve-outs, and assignment restrictions reviewed in full, not just skimmed at a surface level.
What to listen for: A genuine specialist will be able to discuss specific lease clauses and what they mean for your obligations. A generalist will say "we recommend you hire an attorney to review the lease" — meaning they can't do it themselves.
3. Do you have access to off-market NNN inventory?
The publicly listed NNN market — LoopNet, CoStar, Marcus & Millichap listings, CBRE listings — represents a fraction of actual NNN deal flow. The best deals are transacted off-market: through developer sale-leasebacks, direct seller relationships, broker-to-broker networks, and private equity portfolio dispositions.
A NNN broker with genuine off-market access can present you with deals that aren't competed for yet. This matters enormously for 1031 exchange buyers (who need to identify within 45 days) and for buyers who want to pay fair cap rates rather than the premium that public marketing creates.
What to listen for: "Off-market access" is overused. Ask specifically: what are your sources? Developer relationships? Direct seller relationships? Specific broker networks? A specialist will be able to name them. A generalist will say "we have a wide network" without specifics.
4. How do you handle 1031 exchange deadlines?
If you're completing a 1031 exchange — or even considering one — this question is critical. The 45-day identification window requires ready inventory, not a promise to "search actively." A broker who has never managed a 1031 exchange under deadline pressure will learn on your transaction.
A specialist will describe maintaining current inventory for exchange buyers, have a process for rapid property identification, understand QI coordination requirements, and have closed multiple 1031 exchanges under tight timelines. Ask for specifics: how many 1031 exchanges have you completed? What happens if my identification deadline is 30 days away when I close my sale?
What to listen for: Specifics. Numbers. A process. "We can definitely help" without specifics is not an answer.
5. What tenants do you specialize in, and which do you recommend staying away from?
A NNN specialist has a point of view on tenant credit. They know which tenants are investment grade vs. speculative, which leases have landlord-friendly vs. tenant-friendly structures, and which categories are facing structural headwinds (pharmacy consolidation, fast casual softness, gas station EV transition).
If a broker recommends every tenant with equal enthusiasm, they're a generalist presenting inventory rather than a specialist managing your risk. A real specialist will say something like: "I won't work with below-investment-grade tenants for 1031 exchange buyers" or "I'm cautious on standalone Walgreens with shorter lease terms right now because of the bankruptcy news." Opinions backed by reasoning signal expertise.
What to listen for: Specific opinions on tenants — including tenants they'd avoid. Anyone who is enthusiastic about everything knows nothing deeply.
6. Do you charge the buyer, or are you paid by the seller?
In most NNN transactions, the seller pays both brokers' commissions through the sale price. This means a buyer's broker who represents you exclusively can do so at no direct cost to you. This is the standard structure in the NNN market.
However, some brokers charge buyers a retainer, consulting fee, or advisory fee — sometimes in addition to the seller-paid commission. This isn't inherently wrong, but you should know the arrangement upfront and understand exactly what you're paying for.
What to listen for: Full disclosure of all compensation at the start of the engagement, in writing. Any reluctance to put the compensation arrangement in writing is a red flag.
7. Can I speak with recent clients who completed NNN purchases with you?
References are underused in real estate — buyers are often too polite to ask. But in a $2M–$8M transaction, references are not optional. Ask for two or three clients who closed NNN properties within the last 12 months, and actually call them.
What to ask references: Was the lease reviewed thoroughly before they identified? Were any problems found — and how were they handled? Did the broker communicate proactively? Did they hit the timelines promised? Would they use this broker again?
What to listen for: A broker who hesitates, offers "testimonials" instead of direct contact information, or can only produce references from 3+ years ago should be evaluated carefully.
The Bottom Line
A great NNN broker is not the one with the most listings or the biggest firm. They're the one who represents only buyers, reviews leases with the depth of legal training, maintains genuine off-market access, and has a documented process for managing 1031 exchange timelines. Ask these seven questions before you hire anyone — and hold the answers to a high standard. Your passive income stream for the next 20 years depends on getting this decision right.
