Buying commercial property requires more than liking the building.

You need to understand the income, expenses, tenants, financing, and risks. You also need to compare the property against its Houston submarket.

We’ve created this practical checklist to help you evaluate a commercial property for sale in Houston before making an offer.

Start With the Property’s Real Income

Your first job is calculating net operating income, or NOI.

NOI shows how much the property earns after normal operating expenses. It excludes loan payments, income taxes, depreciation, and major capital improvements.

Use this basic formula:

**Potential rental income

• other income
  − vacancy and credit loss
  − operating expenses
  = NOI**

Ask the seller for these documents:

• Current rent roll
• Last three years of operating statements
• Current-year budget
• Property tax bills
• Insurance invoices
• Utility expenses
• Maintenance and repair records
• Management agreements
• Recent capital improvement records

Do not rely only on the seller’s pro forma. A pro forma shows projected income. Your offer should reflect verified performance.

Look closely at each expense line. Understated taxes, insurance, repairs, or utilities can make a deal look better than it performs.

Example: Turning NOI Into Value

Imagine a Houston retail property produces:

• Annual effective income: $600,000
• Operating expenses: $210,000
• NOI: $390,000

If comparable properties trade near a 6.5% cap rate, the estimated value looks like this:

$390,000 ÷ 0.065 = $6,000,000

That calculation gives you a starting point. It does not provide the final offer price.

You still need to review the leases, tenant quality, physical condition, financing, and future capital needs.

Use Cap Rate Carefully

The capitalization rate, or cap rate, measures the property’s unleveraged return.

The formula is simple:

Cap rate = NOI ÷ purchase price

A property with $390,000 in NOI and a $6 million price has a 6.5% cap rate.

Houston cap rates vary widely by property type and risk. Recent market sources place many stabilized Houston commercial assets in the mid-5% to high-7% range. Office properties with higher vacancy can trade at wider cap rates. Newer industrial, medical office, and strong retail assets often command tighter pricing.

You can review current Houston market listings through LoopNet’s commercial property listings. You can also compare local cap-rate commentary from HAR’s Houston commercial real estate analysis.

Remember these important points:

• A higher cap rate usually reflects higher risk.
• A lower cap rate usually reflects stronger income quality.
• A cap rate does not show your loan payments.
• A cap rate does not guarantee future income.
• A seller’s NOI may differ from your verified NOI.

We always recommend calculating the cap rate using both the seller’s numbers and your own underwriting.

Review the Lease Structure

Lease structure can change your actual return significantly.

The two structures you’ll see most often include NNN leases and gross leases.

NNN Leases

With a triple-net lease, the tenant generally pays:

• Property taxes
• Building insurance
• Common-area maintenance

NNN leases can create more predictable ownership expenses. However, you still need to read the lease carefully.

Some leases cap expense recoveries. Others exclude specific repairs. Some tenants may have renewal options or termination rights.

Gross Leases

With a gross lease, the landlord usually pays more property expenses. The tenant pays rent, while the owner handles many operating costs.

Gross leases can work well in office buildings. They can also create more expense volatility for the owner.

Look for:

• Base rent
• Annual escalations
• Expense reimbursements
• Free-rent periods
• Tenant improvement obligations
• Renewal options
• Termination clauses
• Assignment rights
• Personal or corporate guarantees

A property with strong headline rent may still underperform. Large tenant improvement packages and leasing commissions can reduce your real return.

Analyze Vacancy and Absorption

Vacancy tells you how much space sits empty. Absorption shows whether the market is gaining or losing occupied space.

You need both numbers.

A market with 8% vacancy and positive absorption may be improving. A market with 8% vacancy and negative absorption may be weakening.

Houston’s 2026 market remains divided by property type. The Harris Central Appraisal District 2026 Market Trends Report describes:

• Industrial vacancy near the 7% range
• Retail vacancy around 5.3%
• Office vacancy near 20% in the cited market data
• Medical office occupancy near 90%

These figures are market-level indicators. Your property may perform very differently.

Check vacancy by:

• Building class
• Property age
• Tenant type
• Floor size
• Parking availability
• Proximity to major roads
• Nearby new construction

Also ask how long vacant space typically takes to lease. A small vacancy may become expensive if the space requires major renovations.

Compare Houston’s Major Submarkets

Your deal’s location affects tenant demand, future rent growth, and resale value.

Inner Loop

Inner Loop properties can benefit from density, walkability, hospitals, universities, and established neighborhoods.

Retail and mixed-use assets may perform well near strong residential demand. Older office or industrial buildings require more careful analysis.

We recommend checking parking, access, zoning, redevelopment potential, and nearby competing projects.

Energy Corridor

The Energy Corridor remains a major employment center. It offers strong highway access and a deep corporate tenant base.

However, office performance varies sharply by building quality. Newer, amenitized buildings can attract tenants faster than older properties.

Review current occupancy, tenant renewal probability, and required capital improvements. Do not assume every Energy Corridor building benefits equally from the submarket’s name.

Northwest Industrial

Northwest Houston continues to attract distribution, manufacturing, logistics, and warehouse users.

The area offers major highway access and proximity to growing residential populations. New deliveries can increase competition, though modern facilities may continue attracting larger tenants.

For industrial properties, review clear height, loading capacity, truck courts, parking, power, drainage, and access restrictions.

Texas Medical Center

The Texas Medical Center creates specialized demand for medical office, research, housing, hospitality, and service-oriented retail.

Medical office properties can offer more stable demand. They still require careful tenant review.

Check the tenant’s healthcare system affiliation, lease term, medical buildout, licensing needs, and relocation risk. Specialized space may take longer to lease if the current tenant leaves.

Test the Financing Before You Offer

A deal can show a strong cap rate and still produce weak cash flow.

Start with your lender before submitting an offer. Ask for estimated terms based on the actual property.

Review:

• Interest rate
• Loan-to-value ratio
• Amortization period
• Loan term
• Debt-service coverage ratio
• Rate lock requirements
• Prepayment penalties
• Reserves
• Recourse provisions
• Balloon payment risk

Then calculate cash-on-cash return.

Cash-on-cash return measures annual cash flow against your invested equity. It accounts for debt service, unlike the cap rate.

Run at least three scenarios:

1. Base case: Current occupancy continues.
2. Downside case: Vacancy rises and expenses increase.
3. Upside case: Rents grow and vacant space leases faster.

Your deal should survive the downside case. We do not recommend relying on perfect occupancy or cheaper future financing.

Complete Due Diligence Before Removing Contingencies

Your due diligence period protects your investment.

We recommend reviewing these areas before you commit fully:

Financial

• Verify every income and expense item.
• Compare rent collections against the rent roll.
• Review delinquency and bad debt.
• Confirm security deposits.
• Recalculate property taxes.
• Check insurance availability and premiums.

Physical

• Order a professional property inspection.
• Review the roof, structure, HVAC, plumbing, and electrical systems.
• Inspect parking and drainage.
• Check for deferred maintenance.
• Request a capital needs estimate.

Legal and Environmental

• Order a title commitment.
• Review surveys and easements.
• Confirm zoning and permitted use.
• Order an environmental assessment.
• Check floodplain and drainage information.
• Review certificates of occupancy.

Tenant and Lease

• Confirm tenant payment history.
• Read every lease and amendment.
• Verify options and renewal dates.
• Review tenant improvement obligations.
• Check exclusivity clauses.
• Identify near-term expirations.

Market

• Review competing properties.
• Compare recent sales.
• Study asking and achieved rents.
• Check new construction.
• Review vacancy and absorption trends.

Build Your Offer Around Risk

The best offer does more than match the asking price.

It reflects the property’s actual income and future obligations.

You may need to adjust your offer for:

• Below-market leases
• Near-term lease expirations
• Large vacant spaces
• Roof or HVAC replacement
• Weak tenant credit
• High insurance costs
• Unfunded tenant improvements
• Environmental concerns
• Limited parking
• Aggressive seller projections

We also recommend requesting appropriate contingencies. These may cover financing, inspections, title, environmental review, leases, and property records.
