Most new CRE investors come from residential — either as homeowners or as single-family rental investors. The transition is bigger than it looks. Almost every mechanical detail of a deal works differently on the commercial side, and those differences are where the money is.

Here are the nine that matter most.

1. Valuation: income vs. comps

Residential: Property value is set by comparable sales. A three-bedroom house is worth what similar three-bedroom houses nearby sold for. The house doesn't have to generate any income to be worth something.

Commercial: Property value is set by net operating income divided by cap rate.

This single difference is the most important thing to internalize about CRE. It means:

You can't pay more than the NOI justifies (no matter how nice the building is)
Raising NOI directly raises value (the "forced appreciation" play from the previous lesson)
The same building can be worth two very different numbers at two different cap rates
Comps matter, but only to set the cap rate — not to set the price directly

2. Financing: commercial loans vs. residential mortgages

| | Residential | Commercial | |---|---|---| | Loan term | 15–30 years | 5–10 years (usually) | | Amortization | Fully amortizing | 20–30 years, balloon at term | | Rate type | Often fixed for full term | Fixed for 5–10 years, then resets | | Recourse | Always personal | Sometimes non-recourse | | Qualification | Based on your income and credit | Based on the property's income | | LTV | Up to 97% | 55%–75% typical | | Underwriting time | 30–45 days | 60–90 days | | Fees | Small | 1% origination, legal, appraisal ($3K–$15K) |

The biggest mindset shift: on a commercial loan, the lender cares more about the property's income than about you. DSCR (debt service coverage ratio) matters more than your W-2. This is both a relief (no W-2 needed) and a challenge (the deal has to actually cash flow).

3. Lease law: tenant protections

Residential: Heavy tenant protections. In Florida, landlords face specific eviction procedures, required notices, limits on security deposits, habitability standards, and state-specific statutes governing almost every aspect of the landlord-tenant relationship. Mistakes create liability.

Commercial: The lease is king. Florida commercial leases are enforced mostly as written, with minimal statutory overlays. If it's in the lease, it's the rule. Commercial tenants are presumed to be sophisticated business parties who can negotiate for themselves.

Why it matters: A commercial landlord has far more freedom to write a lease that protects their investment — and far more freedom to enforce it. A 5-year NNN lease with a personal guarantee is a bulletproof asset.

4. Lease length

Residential: 12 months. Rarely longer.

Commercial: 3 to 25 years, with 5 to 10 being most common for office/retail/industrial and 20+ for net-lease retail. Long leases are the default on the commercial side, and they fundamentally change the risk profile.

This is why CRE is often called "bond-like" — a 10-year lease with a credit tenant behaves more like a corporate bond than a traditional real estate investment.

5. Rent escalations

Residential: Rents typically stay flat during the lease, then reset at renewal.

Commercial: Rents are almost always scheduled to increase — usually 2–3% annually, or by CPI, or with 10% bumps every 5 years. Every lease has a built-in growth curve baked in. Your cash flow in year 5 is often 10–15% higher than year 1 with no action required.

6. Who pays operating expenses

Residential: The landlord pays almost everything — property taxes, insurance, maintenance, capital improvements. Rent is roughly "gross."

Commercial: Depends entirely on the lease structure:

Gross lease — landlord pays everything (rare in modern CRE)
Modified gross — landlord pays some, tenant pays some (common in office)
Net lease (N) — tenant pays property taxes
Double net (NN) — tenant pays taxes and insurance
Triple net (NNN) — tenant pays taxes, insurance, and maintenance
Absolute NNN — tenant pays everything, including roof and structure

The more expenses the tenant covers, the closer the deal feels to a bond — predictable, low-management, lower upside but lower downside.

7. Property management

Residential: You can self-manage a single-family rental or a small duplex without much difficulty.

Commercial: Depends heavily on the asset class:

NNN retail — essentially zero management (tenant handles everything)
Single-tenant industrial — minimal management
Multi-tenant retail/office — active management required
Multifamily — heavy management (most work per dollar)
Self-storage — active but systematized

Many investors start in CRE specifically to reduce management workload. Picking NNN retail or triple-net industrial lets you own $5M in real estate while spending fewer hours per month than on a single rental house.

8. Taxes and depreciation

Residential: 27.5-year depreciation schedule on the building.

Commercial: 39-year depreciation schedule — slower, but the asset is usually much bigger, so total annual deductions are larger. Plus, commercial properties lend themselves much better to cost segregation studies, which can accelerate depreciation dramatically and generate huge paper losses in year 1.

Commercial real estate also qualifies for the same 1031 exchange treatment as residential, and sophisticated owners use it to compound gains tax-free for decades.

9. Exit strategy and buyer pool

Residential: You sell to a homebuyer or another landlord. The pool of buyers is huge, the marketing is standardized, and liquidity is high.

Commercial: You sell to another investor. The pool is much smaller but also more rational — buyers underwrite based on numbers, not emotion. That can be either a blessing (no emotional lowball offers) or a curse (no sentimental premium).

Exit timing matters more on the commercial side because the pool of buyers changes with the capital markets. During a rising-rate environment, cap rates expand and values fall — even if NOI stays flat. Smart investors plan their exit with both NOI growth and cap rate cycles in mind.

What to take away

CRE is valued on income, not comps — internalize this above all else.
Commercial loans look at the property's income, not yours.
Commercial leases are enforced mostly as written — the lease is king.
Leases are much longer in commercial, often with built-in rent escalations.
The NNN vs. gross lease continuum determines how much work you do as a landlord.
Commercial management ranges from zero (NNN) to heavy (multifamily) — pick the asset class that matches your desired workload.

Next lesson: why commercial real estate is so often the best investment available, even compared to stocks, bonds, and single-family rentals.
