Intro to Commercial Real Estate
Asset classes, how CRE differs from residential, and where first-time commercial investors should start.

Commercial real estate (CRE) is a different game than residential — longer leases, larger checks, and returns driven by income rather than appreciation. Here's the foundation.
The five CRE asset classes
- ▸Multifamily (residential): apartment buildings (5+ units). Most accessible for first-time CRE investors. Driven by housing demand.
- ▸Office: Class A (trophy towers) → Class C (suburban flex). Post-COVID occupancy pressure. High CapEx, sticky leases.
- ▸Retail: from neighborhood strip centers to regional malls. NNN leases put operating expenses on the tenant. Under structural pressure from e-commerce.
- ▸Industrial: warehouses, distribution, flex space. Lowest management intensity. Cap rates compressed by e-commerce demand.
- ▸Mixed-use: retail/office at base, residential above. Anchored by a strong street or transit.
How CRE differs from residential
- ▸Income, not comps: CRE values on NOI ÷ Cap Rate, not comparable sales. A 50bp cap-rate move changes value by ~8%.
- ▸Lease length: commercial leases run 3–10+ years (vs. residential 1-year). More stability, less turnover — but longer vacancy when a tenant leaves.
- ▸Tenant pays more: NNN leases push taxes, insurance, and maintenance onto the tenant. Your gross rent is closer to your net.
- ▸Financing: commercial loans are shorter (5–10 years, often with a rate reset) and based on DSCR, not personal income.
- ▸Larger checks: minimum viable deals start higher; syndication and partnerships are common.
Where to start
For first-time commercial investors:
- Small multifamily (5–20 units) — the bridge from residential. Same tenant profile, larger income, still learnable.
- Single-tenant NNN with a credit tenant (national chain on a long lease) — bond-like, lower management.
- Syndications as a limited partner — learn the business with someone else's deal and your capital, before running your own.
