What Is Commercial Real Estate?
Commercial real estate (CRE) is property that generates income from business tenants. Office, retail, industrial, multifamily (5+ units), hotels. Unlike residential (1–4 units), commercial is valued by NOI ÷ cap rate — a $400K NOI building at 6% cap is worth $6.67M. You typically need 25–40% down, and most individual investors access CRE through syndication — pooled capital with a sponsor running the deal. Lease structures (NNN, gross) determine who pays taxes, insurance, and maintenance.
Commercial real estate is income-producing property used for business purposes — office buildings, retail spaces, industrial warehouses, and multifamily (5+ units) — valued by NOI and cap rate, not comparable sales alone.
At a Glance
- What it is: Income-producing property for business use — office, retail, industrial, multifamily 5+, hotel
- Why it matters: Valued by income, not comps; NOI and cap rate drive every deal
- How to use it: Buy directly (25–40% down, commercial loan) or invest via syndication
- Common threshold: 5+ units = commercial (residential financing stops at 4); cap rates vary 4.5–9% by asset class and market
How It Works
Commercial real estate is valued by the income it produces. Value = NOI ÷ cap rate. A building with $500,000 in net operating income at a 6% cap rate is worth $8.33 million. Drop the cap to 5% and it's $10 million. The math is that simple — and that unforgiving.
Asset classes. Office, retail, industrial, multifamily (5+ units), hotel, mixed-use. Each has different lease structures. NNN (triple net) means the tenant pays property taxes, insurance, and maintenance — you collect rent and pass through expenses. Gross lease means you pay everything. Modified gross splits the difference. NNN shifts risk to the tenant; gross shifts it to you.
The 5-unit line. Residential financing (Fannie, Freddie, FHA) stops at 4 units. Five units and up = commercial. Different lenders, different underwriting. You'll need 25–40% down, and lenders will underwrite on DSCR — debt service coverage ratio — not your personal income. Typically 1.25x: NOI must cover the mortgage by 25%.
Depreciation. Commercial uses 39-year straight-line depreciation, not 27.5 like residential. Cost segregation can accelerate that — but that's a separate strategy. The point: tax treatment differs from residential.
Real-World Example
240-unit multifamily in Phoenix, 2024.
Purchase price: $48M. NOI: $2.4M. Cap rate: 5%. Equity: $12M (75% LTV). Debt: $36M at 5.5%, 10-year term.
You invest $100,000 as a limited partner in a syndication. Preferred return: 6%. Hold: 5 years. Year 1–2: light rehab, cash flow covers preferred. You get $6,000/year. Year 3–5: rents up 12%, value-add complete. Exit at $62M. Your share: ~$142,000. Total return: ~12% IRR, 1.78x equity multiple.
You didn't buy the building. You bought a slice. That's how most investors access commercial — through syndications, not direct ownership.
Pros & Cons
- NOI-driven valuation — value tied to income, not sentiment
- Scale: $48M multifamily isn't in your reach alone; $100K in a syndication is
- NNN leases shift operating risk to tenants
- Depreciation benefits (39-year, cost seg possible)
- Institutional capital flows here — liquidity and professional management
- 25–40% down for direct purchase — high capital barrier
- Commercial loans have shorter terms, balloon payments, refinance risk
- Due diligence is heavier — Phase I environmental, lease review, tenant credit
- Syndication requires accredited status for most deals; capital locked for 3–10 years
Watch Out
- Cap rate risk: A 4.5% cap in a hot market can compress to 5.5% when rates rise — that's a 18% value drop with no change in NOI. Don't chase yield in cap-rate-compressed markets without a value-add plan.
- Lease roll risk: Single-tenant retail or office with a lease expiring in 2 years? Vacancy = zero income. Multi-tenant spreads the risk.
- Operator risk: In syndication, your returns depend on the sponsor. Vet track record, fee structure, and alignment. A bad operator can wipe out your capital.
- Exit risk: Commercial is illiquid. You can't sell a $100K LP interest on a Tuesday. Plan for the hold period.

The Takeaway
Commercial real estate is where NOI and cap rate run the show. Value = income ÷ cap rate. Most individual investors get in through syndication — pooled capital, sponsor-run deals, accredited-only. Direct purchase means 25–40% down and commercial loan terms. If you're coming from residential, the rules are different: income drives value, leases matter more than comps, and scale is the name of the game.
