You can sell commercial real estate without a realtor, and doing so puts the broker commission back in your pocket. The tradeoff is that you handle every step yourself: pulling financials, pricing the asset, marketing to qualified buyers, negotiating terms, and running a closing that involves tax withholding, environmental liability, and deed transfer. One professional you should not skip is a commercial real estate attorney. An experienced attorney costs far less than a broker’s commission and will draft or review your purchase agreement, clear title issues, and keep you out of the liability traps that catch first-time sellers.
Build the Document Package Before You List
Serious buyers ask for the same documents in the same order. Have them ready and you look credible. Scramble to pull them after an offer comes in and you lose leverage.
Start with the Trailing 12-Month profit and loss statement, the T-12. It tracks every dollar of income and operating expense over the past year and must reconcile with your bank statements. Any discrepancy becomes a renegotiation point.
Pair the T-12 with a current rent roll: every tenant, their space, their monthly rent, and the start and end dates of their leases. Buyers use it to calculate occupancy and forecast revenue. Keep it updated through the day you hand it over. A rent roll three months stale raises questions about what changed.
Organize every signed lease, including amendments, renewal options, and side letters. Buyers need to see whether leases are triple net (tenants pay taxes, insurance, and maintenance) or gross (you absorb those costs), because that structure determines what a new owner actually collects. Missing leases slow due diligence and hand buyers a reason to cut price.
Request a tenant estoppel certificate from each tenant before listing. The estoppel is a signed statement confirming the current lease terms, that rent is current, and whether any claims exist against the landlord. It locks tenants into what they’ve acknowledged and prevents disputes after closing. Lenders routinely require them, so collecting them early saves weeks later.
Environmental and Physical Property Data
A Phase I Environmental Site Assessment is one of the most useful documents you can hand a buyer upfront. It reviews the property’s history, past uses, and surrounding land to flag contamination risks. The current standard is ASTM E1527-21, which satisfies the EPA’s All Appropriate Inquiries rule. Phase I reports for standard commercial properties typically cost between $2,000 and $5,000, with industrial sites running higher. If the Phase I flags a concern, a Phase II involving soil and groundwater sampling costs significantly more.
Environmental liability is worth understanding even if you believe your site is clean. Under federal Superfund law, both current and former owners can be held responsible for cleanup costs if hazardous substances are found. Buyers who perform proper environmental due diligence may qualify for protections as bona fide prospective purchasers, but sellers who caused or knew about contamination generally cannot escape responsibility.
Compile the physical data buyers need for underwriting: total building square footage, lot size, year built, roof age, HVAC details, and the property’s zoning designation. Zoning determines what a buyer can do with the property, and a mismatch between the buyer’s intended use and the current classification kills deals. Pull your zoning from the local planning department and include it in your marketing materials.
Price It Using NOI and a Cap Rate
Commercial pricing starts with Net Operating Income. Calculate NOI by subtracting all operating expenses from total annual income. Operating expenses include property taxes, insurance, utilities, management fees, and common area maintenance. Debt service and major capital expenditures stay out of the calculation, because NOI measures what the property earns independent of financing or ownership choices.
Convert NOI into value using a capitalization rate: the rate of return buyers expect for properties like yours in your market. If comparable buildings trade at a 6% cap rate and your NOI is $120,000, the math puts your value at $2,000,000. Cap rates vary by property type, location, and market conditions. You can pull recent cap rate data from commercial listing platforms, local tax assessor records, and industry reports.
Add a comparable sales analysis. Look for similar properties sold in the last six to twelve months, weighing square footage, tenant quality, lease terms, and location. Public property tax records are the most reliable free source for historical sale prices. Adjust up or down for differences in condition, occupancy, and lease structure.
For properties worth more than roughly $1 million, hiring an independent commercial appraiser is worth the cost. Fees generally run $2,500 to $6,000 depending on complexity. Lenders almost always require an independent appraisal before funding, so having one in hand signals credibility and prevents late-stage price fights.
Reach the Buyers Who Actually Buy Commercial
Commercial buyers don’t browse Zillow. Your property needs to appear on platforms built for commercial real estate, such as LoopNet and Crexi. Some platforms offer basic free listings; premium tiers with better search placement and analytics run between $100 and $500 per month. Enter accurate data for property type, square footage, price, and cap rate. Incomplete listings get scrolled past.
Pay for professional photography. Include high-resolution interior and exterior shots, images of specialized features like loading docks or tenant buildouts, and aerial photography showing proximity to highways or retail corridors. Investment groups reviewing dozens of listings decide in seconds based on what they see.
Create an Offering Memorandum, the commercial equivalent of a property brochure. A good OM summarizes the financial highlights (NOI, cap rate, rent roll), property specifications, lease structure, and local market demographics. Upload it as a downloadable PDF inside your listing. Buyers circulate the OM internally before deciding whether to tour the property, so treat it as your primary sales document.
Before sharing detailed financials with any prospective buyer, require a signed non-disclosure agreement. The NDA protects tenant identities, rental rates, planned capital improvements, and investor information from competitors and neighboring owners. Keep it simple and focused on confidentiality of the specific data you’re releasing.
Physical signage still works, especially on high-traffic roads. A large “For Sale By Owner” sign with a direct phone number surfaces local investors and business owners who may not be hunting online.
From Letter of Intent to Signed Contract
Most commercial transactions begin with a Letter of Intent before anyone drafts a full contract. The LOI is a short document outlining the key deal terms: purchase price, earnest money, proposed closing timeline, due diligence period, and major contingencies like financing or zoning approval. It usually includes a confidentiality clause and may grant the buyer an exclusivity period during which you cannot negotiate with other parties.
The LOI is generally non-binding on the deal itself, but specific provisions like confidentiality and exclusivity can be enforceable depending on the language, so read before you sign. Its real value is efficiency: both sides agree on fundamentals before paying attorneys to draft a full contract. If you can’t agree on price and timeline at the LOI stage, you’ve saved weeks.
The Purchase and Sale Agreement
The Purchase and Sale Agreement is the binding contract that governs the entire transaction. Skipping a real estate attorney here is a serious risk. Commercial PSAs are substantially more complex than residential contracts, covering lease assignments, environmental indemnification, representations and warranties, and default remedies. Templates exist through state bar associations and legal document services, but a template alone will not address the specific risks of your deal.
Earnest money typically runs 1% to 5% of the purchase price in commercial transactions and is held in escrow by the title company or closing attorney. The PSA should spell out exactly when the deposit becomes non-refundable, usually tied to the expiration of the due diligence period.
The due diligence period gives the buyer a set window to inspect the property, review financial records, examine leases, and verify environmental conditions. Thirty to sixty days from contract execution is common. During this window the buyer can typically terminate for any unsatisfactory finding and recover their earnest money. Once the period expires, the deposit usually goes “hard”: the buyer forfeits it if they walk away without a contractual excuse.
Contingencies and Prorations
Contingencies are contractual escape hatches tied to specific conditions. A financing contingency lets the buyer exit if they can’t secure a commercial mortgage by a stated deadline. An inspection contingency covers structural or mechanical defects. If the buyer plans to change the property’s use, a zoning or entitlement contingency may apply. Every contingency needs a hard deadline. Open-ended contingencies let buyers tie up your property indefinitely.
The PSA also needs to address how income and expenses split on the closing date. Property taxes, utility bills, and collected rents are prorated by the number of days each party owns the property. If you collected a full month’s rent but close on the 15th, the buyer gets roughly half as a credit at closing. Security deposits transfer to the buyer in full rather than being prorated. Get these numbers into the contract early so nothing is improvised at the closing table.
Disclosure: Where “As-Is” Doesn’t Save You
Commercial sales carry fewer mandatory disclosure requirements than residential, but that does not mean you can stay silent. Most states impose liability on sellers who fail to disclose or actively misrepresent facts that are material to the transaction. A material fact is anything a reasonable buyer would consider important when deciding whether to purchase and at what price.
Many states follow a “buyer beware” approach for commercial property, placing the investigative burden on the buyer. Even in those states, sellers generally have a duty to disclose known latent defects: problems a buyer couldn’t discover through reasonable inspection. A cracked foundation hidden behind a finished wall, ongoing litigation with a tenant, or a history of flooding without visible damage are the kinds of issues that create liability if you stay quiet.
Be careful with “as-is” clauses. They are common in commercial contracts, but an as-is provision does not necessarily shield you from liability for actively concealing known defects. In some states, liability for failing to disclose facts that materially affect value cannot be waived by an as-is clause. When in doubt, disclose. The cost of defending a fraud or misrepresentation claim after closing far exceeds any price concession from being upfront.
Closing and Title Transfer
Closing starts when you open escrow with a title company or closing attorney. That neutral third party manages the flow of funds, coordinates document signing, and handles recording. The title company runs a title search to identify liens, mortgages, easements, or other encumbrances. Anything outstanding has to be cleared before title can transfer.
Title insurance protects the buyer and lender against ownership defects the search might have missed. Lenders almost always require a lender’s policy as a financing condition, and buyers frequently buy an owner’s policy as well. Who pays for which policy varies by local custom; your attorney or title company will walk you through it.
Most commercial transactions use either a special warranty deed, where you guarantee title only against defects that arose during your ownership, or a general warranty deed, where you guarantee against all defects including those predating your ownership. The deed must be notarized before it can be recorded. Once documents are signed and funds are in escrow, the deed is recorded with the local county recorder’s office and the escrow agent wires your proceeds.
FIRPTA Withholding for Foreign Sellers
If you are not a U.S. citizen or resident, the buyer is required to withhold 15% of the total amount realized on the sale and remit it to the IRS under the Foreign Investment in Real Property Tax Act. This is not an added tax; it is an advance payment credited against what you owe when you file your U.S. return. Foreign corporations face a 21% withholding rate on the gain recognized from distributing a U.S. real property interest to foreign shareholders.1Office of the Law Revision Counsel. 26 USC 1445 – Withholding of Tax on Dispositions of United States Real Property Interests
IRS Reporting
The person responsible for closing the transaction, usually the settlement agent or closing attorney, must file IRS Form 1099-S reporting the gross proceeds. The only exception is a de minimis transfer where total consideration is less than $600. Starting in tax year 2026, digital assets used in real estate transactions must also be reported on Form 1099-S.2Internal Revenue Service. Instructions for Form 1099-S (Rev. December 2026)
Plan for the Tax Hit Before You List
Selling commercial real estate triggers multiple layers of federal tax, and how much you owe depends on how long you held the property, how much depreciation you claimed, and your overall income level. Planning before you list can save a meaningful share of the proceeds.
Capital Gains, Depreciation Recapture, and NIIT
If you held the property more than a year, profit on the sale is taxed at long-term capital gains rates of 0%, 15%, or 20% depending on taxable income. For 2026, the 20% rate kicks in at $545,500 for single filers and $613,700 for married couples filing jointly. The surprise for commercial sellers is depreciation recapture. Any depreciation you claimed (or could have claimed) during ownership is recaptured, and for commercial buildings this unrecaptured Section 1250 gain faces a maximum federal rate of 25%, applied before the remaining gain is taxed at capital gains rates.
On top of that, if your modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly), the 3.8% Net Investment Income Tax applies to the gain.3Internal Revenue Service. Questions and Answers on the Net Investment Income Tax These thresholds are not indexed for inflation, so more sellers hit them every year. For a property with substantial accumulated depreciation and a large gain, the combined effective federal rate can easily reach 30% or higher.
Deferring the Tax With a 1031 Exchange
A Section 1031 like-kind exchange lets you defer all capital gains and depreciation recapture by reinvesting the sale proceeds into another qualifying property. Both the property you sell and the property you buy must be real property held for business use or investment. You cannot use a 1031 exchange for property held primarily for resale, and U.S. property cannot be exchanged for foreign property.4Office of the Law Revision Counsel. 26 USC 1031 – Exchange of Real Property Held for Productive Use or Investment
The deadlines are strict and non-negotiable. From the date you transfer the sold property, you have 45 days to identify potential replacement properties in writing and 180 days to close on the replacement. Miss either deadline and the exchange fails, making the entire gain taxable in the year of sale.4Office of the Law Revision Counsel. 26 USC 1031 – Exchange of Real Property Held for Productive Use or Investment The proceeds must be held by a qualified intermediary during the exchange period. You cannot touch the money yourself, even briefly, without disqualifying the exchange. Report a completed exchange on IRS Form 8824 with your return for the year of the sale.
If a 1031 exchange might fit your situation, talk to a tax advisor before you list. The qualified intermediary has to be in place before closing, and that is not something you can arrange on the fly.
