How to Buy Your First Commercial Property in San Antonio

Step 1: Set your buying criteria and all-in cash budget

Your first commercial property should fit your available cash, management capacity, and tolerance for vacancy—not just your preferred purchase price. Decide whether you want rental income from tenants or a building for your own business. That distinction affects both underwriting and financing.

Keep the initial search narrow: one or two property types and a manageable geographic area. A small office building, neighborhood retail property, and flex warehouse require different leasing knowledge. Compare actual access, parking, tenant needs, and competing space rather than treating all San Antonio commercial real estate as one market.

Calculate spendable acquisition cash only after protecting your household emergency fund and other business obligations. For a deeper budget framework, see [how much cash you need to buy commercial property in San Antonio](/resources/how-much-cash-buy-commercial-property-san-antonio).

1. 1Write down your target property type, location, maximum cash commitment, income goal, and intended holding period.
2. 2Budget separately for the down payment, lender charges, appraisal, title and survey work, legal review, inspections, and environmental review.
3. 3Add immediate repairs, tenant improvements, leasing commissions, and operating reserves. Get property-specific quotes instead of applying one closing-cost percentage to every deal.
4. 4Set a reserve floor that remains available after closing. Stress-test whether it could cover a major repair and several months of reduced collections at the same time.

Step 2: Speak with commercial lenders before making offers

For a commercial loan in San Antonio, start with a lender conversation about the borrower and the property—not just the interest rate. Your liquidity, experience, guarantor strength, tenant mix, lease expirations, and intended use all belong in that conversation.

Frost Bank and Broadway Bank are two local institutions to contact about current commercial financing options. Treat them as starting points, not endorsements or promises of approval. Ask specifically whether the bank will consider your property type, transaction size, and investor-owned versus owner-occupied structure.

If your operating business will occupy the building, ask an SBA lender whether an SBA-backed structure fits. SBA 504 financing can support eligible owner-occupied business real estate, but it is not a program for passive investment rental property. Have the lender confirm current eligibility and occupancy requirements before relying on it.

Request written preliminary terms. A lender's initial interest does not replace property underwriting, appraisal, or final credit approval.

1. 1Prepare personal financial statements, tax returns, liquidity documentation, an ownership-entity outline, and a short description of your investment plan.
2. 2Ask about maximum leverage, required debt-service coverage, borrower equity, recourse, reserves, and liquidity remaining after closing.
3. 3Compare interest rate, amortization, loan maturity, balloon balance, prepayment provisions, fees, and any rate-reset terms.
4. 4Ask which third-party reports the lender must order and when fees become nonrefundable. Avoid paying for reports the lender cannot accept.

Step 3: Screen properties using verified income

Start with the seller's rent roll, leases, trailing 12-month operating statement, tax information, and known capital needs. The listing package is a starting point, not proof of performance. Separate rent actually collected from projected rent, and identify concessions, delinquencies, reimbursements, and near-term lease expirations.

Calculate net operating income, or NOI, as effective property income minus operating expenses, before debt service and income taxes. Keep major capital projects separate from routine operating expenses, but include them in your cash plan. Ask how your lender treats reserves and other adjustments in its own NOI calculation.

Build your own expense assumptions for property taxes, insurance, management, maintenance, and utilities. Do not assume the seller's tax bill or insurance premium will be your cost. Review [what property taxes to underwrite in Bexar County](/resources/what-property-taxes-underwrite-bexar-county-investment-property), and obtain a commercial insurance quote for the actual use and occupancy.

DSCR equals underwritten NOI divided by annual debt service. Use the lender's required coverage ratio rather than a universal cutoff; the [commercial DSCR guide](/resources/what-is-dscr-commercial-real-estate) explains why coverage can limit your loan amount.

1. 1Reconcile the rent roll to executed leases and available collection records. Confirm which expenses tenants reimburse and whether those amounts have actually been collected.
2. 2Model an as-is case, a downside case, and an upside case. Do not use future lease-up or rent increases to disguise weak current performance.
3. 3Check the cost and downtime of replacing the largest tenant, including improvements, commissions, and unreimbursed expenses.
4. 4Set your maximum price using both lender constraints and your cash-return requirements. Use the [maximum commercial purchase price framework](/resources/how-to-calculate-maximum-price-commercial-property) before negotiating.

Step 4: Negotiate a contract that gives you time to verify

An attractive price is not enough if the contract leaves you committed before you can verify financing, leases, and physical condition. A letter of intent can outline major terms, but have counsel identify any binding provisions before signing it.

Work with your REALTOR® and a Texas real estate attorney to address inspection rights, document delivery, financing and appraisal contingencies if negotiated, title and survey objections, access for testing, and closing conditions. Do not assume a commercial contract includes the protections or termination rights you have seen in a residential purchase.

For planning—not as a San Antonio market average—consider a 60–120-day contract-to-closing allowance for a financed purchase while you obtain a transaction-specific schedule. Straightforward deals may close sooner; environmental findings, title issues, financing complexity, or incomplete records can require longer.

1. 1Define earnest money, any additional deposits, who holds them, and exactly when funds become nonrefundable under the contract.
2. 2Specify required seller documents and delivery dates, including leases, amendments, service contracts, operating records, and available reports.
3. 3Set deadlines that accommodate lender reports and specialist review, with extension rights if negotiated.
4. 4Calendar every notice and objection deadline. Plan your go-or-no-go review before the last day.

Step 5: Complete San Antonio-specific due diligence

Confirm the property's governing jurisdiction first. A San Antonio mailing address is not enough to determine which authority controls your proposed use. For property inside city limits, verify zoning, applicable approvals, and occupancy requirements with San Antonio Development Services. For Hill Country properties, identify the relevant municipal, county, utility, and other authorities.

Evaluate the building as the next owner, not just as a visitor. Roofs, HVAC systems, drainage, paving, accessibility, electrical capacity, and fire protection can change the economics quickly. For Hill Country properties, investigate water supply, wastewater capacity, legal access, and utility availability early.

Discuss environmental review with the lender and a qualified environmental professional. Historical uses such as automotive service, fuel storage, or dry cleaning warrant particular attention. Do not assume a clean-looking building—or an old report—settles environmental risk.

Review tenant obligations as carefully as physical condition. A lease labeled triple net does not tell you every responsibility. Read the actual provisions for roof and structure, HVAC, expense caps, reconciliations, renewal options, assignment rights, and landlord work.

1. 1Have the title commitment and survey reviewed for ownership, liens, easements, restrictions, encroachments, and legal access.
2. 2Confirm that your intended use and any planned alterations are feasible; investigate parking, loading, flood exposure, drainage, and utility capacity.
3. 3Obtain specialist inspections and written repair estimates. Confirm insurance availability, exclusions, deductibles, and lender requirements.
4. 4Request tenant estoppels where appropriate, along with deposit records, prepaid rent, concessions, arrears, and outstanding landlord obligations.
5. 5Re-underwrite with verified findings, then proceed, renegotiate, or terminate only as your contract permits.

Step 6: Reconcile financing and closing costs

Before closing, replace every important estimate with a quote, invoice, contract obligation, or documented reserve decision. If the appraisal or lender underwriting supports less debt than expected, decide whether additional equity still produces an acceptable investment. Do not automatically fill the gap just because you have already paid for inspections.

Review the settlement statement, loan documents, title requirements, insurance binder, and ownership entity with the appropriate professionals. Understand your personal guaranty, balloon maturity, reporting obligations, and any lender-controlled reserves.

Prorations and credits need special attention on an occupied building. Confirm treatment of rents, security deposits, prepaid amounts, property taxes, tenant reimbursements, and unpaid leasing or improvement obligations. Ask your attorney which adjustments may need to be reconciled after closing.

1. 1Obtain final cash-to-close instructions and confirm that your post-closing reserve remains intact.
2. 2Verify wiring instructions through an independently confirmed phone number, not solely through an email thread.
3. 3Complete the final property review and confirm any agreed repairs, deliveries, or tenant-related closing conditions.
4. 4Arrange effective insurance coverage, utility transitions, management onboarding, keys, access codes, and transfer of operating records.

Step 7: Execute a first-90-days ownership plan

Closing is the start of the operating plan. Give tenants clear ownership and payment instructions, establish accounting by income and expense category, and document maintenance responsibilities. Complete safety and insurance-related work promptly.

Track actual collections, expenses, cash reserves, and upcoming lease events against your underwriting each month. Maintain a lease-expiration calendar and begin refinancing planning well before any loan maturity. A long amortization schedule does not necessarily mean a long loan term.

Before you commit to a property, [request a deal analysis](/analyze) to organize the income, debt, repair, and reserve assumptions. For help narrowing the search or coordinating the buying process, [contact Cosmin Ghiurau, a licensed Texas REALTOR®](/contact). Legal, tax, lending, engineering, and environmental questions should go to the appropriate specialists.

1. 1During the first month, verify tenant balances, deposits, recurring contracts, and critical maintenance needs.
2. 2By day 60, compare actual operating results with your acquisition model and investigate material differences.
3. 3By day 90, update the capital plan, leasing priorities, reserve target, and lender-reporting calendar.
