You can sell a commercial property without a realtor in every U.S. state, and on a mid-size deal the commission savings run into the tens of thousands of dollars. On transactions under $1 million, commercial broker fees typically run 4% to 6% of the sale price, so an owner selling a $750,000 office building could retain $30,000 to $45,000 by handling the sale directly. The trade is that you take on every task a brokerage would normally run: legal compliance, financial packaging, marketing, buyer vetting, contract negotiation, due diligence coordination, and closing. The walkthrough below moves through each stage in the order you’ll actually face it, and it ends on the tax consequences that catch most first-time commercial sellers off guard.
Confirm What Your State Requires Before You List
Roughly a third of states require a licensed attorney to be involved in a real estate closing, whether that means preparing the deed, certifying title, or supervising the closing itself. If you’re in one of those jurisdictions, going without an attorney doesn’t save money. It voids the transaction or exposes you to unauthorized-practice-of-law problems. Even in states where an attorney isn’t mandatory, having a real estate lawyer review the purchase and sale agreement on a six- or seven-figure deal is cheap insurance.
Most municipalities also regulate what you must disclose before transferring commercial property. Zoning certificates, certificates of occupancy, and environmental compliance records are commonly required, and the specifics vary by local planning department. Call the office, ask what a commercial seller is required to produce, and build your checklist from their answer rather than a generic template. Missing documents delay closings and, in some cases, give the buyer legal grounds to walk away after you’ve put months into the deal.
Assemble the Financials and Property Records Buyers Will Demand
Commercial buyers evaluate buildings the way analysts evaluate companies. They want auditable income data, not promises. Have at least three years of profit and loss statements and tax returns tied to the property. These records let a buyer verify Net Operating Income, which drives the capitalization rate and ultimately the price someone will pay. Messy or incomplete books invite lowball offers or buyers who disappear once due diligence starts.
Build a detailed rent roll: every tenant, monthly rent, security deposit, lease start and expiration dates, renewal options, and any rent escalation clauses. Buyers will cross-check this against the actual lease documents, so accuracy here speeds the deal and builds credibility. If any leases include Subordination, Non-Disturbance, and Attornment agreements with your lender, pull those too, because they affect how the buyer’s financing interacts with your tenants.
On the physical side, gather building plans, a recent land survey, and your certificate of occupancy or zoning compliance paperwork. The survey confirms boundaries and flags easements or encroachments that could limit what the buyer does with the property. You should also have a Phase I Environmental Site Assessment ready. Most commercial lenders require a Phase I before approving financing, and the report follows the ASTM E1527-21 standard for evaluating whether the site has recognized environmental conditions such as soil or groundwater contamination. A clean Phase I keeps the deal moving. A dirty one triggers a Phase II with physical sampling, which adds weeks and can derail the transaction if you haven’t prepared for it.
Marketing Directly to Commercial Buyers
Commercial buyers don’t browse the sites homebuyers use. Your property needs to appear on commercial-specific listing platforms like LoopNet and Crexi, where institutional investors, private equity firms, and individual commercial buyers search by asset class, location, and cap rate. These platforms charge monthly subscription fees that scale with listing tier and visibility, and the exposure to qualified buyers is hard to replicate through general advertising.
The centerpiece of your marketing is the Offering Memorandum, a document that pulls your financial data, rent roll, property specifications, and local market demographics into one investment case. Treat it as a prospectus for your building. A well-prepared Offering Memorandum lets a buyer run preliminary numbers before requesting a tour or confidential records, which filters out casual inquiries.
Once a buyer gets serious, grant access to a secure digital data room rather than emailing sensitive files. A data room lets you control who sees what, track which documents have been reviewed, and require a non-disclosure agreement before granting access. It protects tenant privacy and proprietary financial detail, and it signals the kind of organizational discipline that gives buyers confidence.
The Purchase and Sale Agreement
The Purchase and Sale Agreement governs price, closing date, and what happens when something goes wrong. In commercial deals this document is heavily negotiated and far more detailed than a residential contract. At minimum it must include the legal names of all parties, the legal description of the property as it appears on the deed, the purchase price, and the earnest money deposit amount with the escrow terms governing that deposit.
Several clauses deserve particular attention when you’re selling without a broker:
- As-is language. Most commercial sales are “as-is,” meaning you disclaim warranties about the building’s condition and the buyer relies on their own inspections. If you offer any warranties instead, spell out exactly what they cover and for how long.
- Closing cost allocation. Unlike residential transactions where regional custom controls, commercial deals negotiate everything. Who pays for title insurance, transfer taxes, recording fees, and the survey should all be written into the agreement.
- Default remedies. If the buyer backs out without a valid contingency, the standard remedy is forfeiture of the earnest money deposit. If you back out, the buyer can typically pursue specific performance, meaning a court can order you to sell. Make sure the default section reflects what you’ve actually agreed to.
- Survival clause. Your representations and warranties don’t automatically expire at closing. Commercial contracts typically specify a survival period, commonly 12 to 18 months, during which the buyer can still bring claims based on statements you made in the agreement.
Standard commercial contract forms are available through local bar associations and legal document services. They’re a reasonable starting point, not a finished product. Every commercial deal has property-specific issues that a form won’t anticipate, which is another reason to have a real estate attorney review the final version before you sign.
Surviving Due Diligence
Once both sides sign the Purchase and Sale Agreement, the due diligence period opens. The window typically runs 30 to 90 days, depending on the property’s complexity, and it’s the buyer’s chance to verify every claim you’ve made. Expect licensed engineers to inspect the roof, HVAC, electrical, plumbing, and foundation. You’re obligated to provide reasonable access and deliver additional records the buyer requests during this period.
Financial verification is where most disputes surface. The buyer will review original lease documents and request estoppel certificates from each tenant. An estoppel certificate is a signed statement from a tenant confirming lease terms, current rent, deposit held, and whether the landlord is in default on any obligations. These certificates lock in facts so the buyer isn’t relying only on your representations. If a tenant’s estoppel contradicts your rent roll, expect the buyer to renegotiate the price or demand a credit.
Most Purchase and Sale Agreements include contingencies that let the buyer walk away without losing the earnest money if certain conditions aren’t met. The common ones are a financing contingency, which allows withdrawal if the buyer can’t secure a loan on acceptable terms, and a title contingency, which allows withdrawal if the title search reveals liens, judgments, or undisclosed ownership claims. A title search performed by a third-party examiner confirms that you can deliver clean title at closing. If any contingency isn’t satisfied within its deadline, the contract typically terminates and the earnest money returns to the buyer.
If the Phase I you provided identified recognized environmental conditions, the buyer’s lender will typically require a Phase II. Phase II investigations involve physical sampling of soil, groundwater, or building materials to quantify the scope of any contamination. Common triggers include a history of industrial use on or near the site, evidence of underground storage tanks, or visible signs of contamination such as discolored soil. The remediation negotiation that follows can reshape the entire deal.
Plan for the Tax Hit Before You List
This is the section most owner-sellers wish they’d read first. The tax implications of selling commercial property are substantial and layered, and they directly affect how much of the sale price you actually keep. Working through them before you list the property gives you time to consider strategies that could defer or reduce the bill.
Long-Term Capital Gains
If you’ve held the property for more than a year, your profit qualifies as a long-term capital gain. For 2026, the federal rates are 0%, 15%, or 20% depending on your taxable income. Single filers pay 0% on gains up to $49,450 of taxable income, 15% on gains between $49,450 and $545,500, and 20% above that. Married couples filing jointly hit the 20% bracket at $613,700. These thresholds come from IRS Revenue Procedure 2025-32, which adjusts them for inflation each year.1Internal Revenue Service. Revenue Procedure 2025-32
Depreciation Recapture
Here’s what surprises people. Even if your capital gains rate would otherwise be 15%, the IRS recaptures the depreciation you claimed on the building at a higher rate. Any gain attributable to depreciation deductions you took over the years is taxed at a maximum rate of 25% as “unrecaptured Section 1250 gain.”2Internal Revenue Service. Topic No. 409, Capital Gains and Losses This applies whether you actually benefited from those deductions or not. Depreciate a building by $200,000 over your ownership and sell at a gain, and that $200,000 portion is taxed at up to 25% before the remaining gain gets the lower capital gains rate.
Net Investment Income Tax
High-income sellers face an additional 3.8% tax on net investment income, which includes gains from selling investment real estate. This surtax applies when modified adjusted gross income exceeds $200,000 for single filers or $250,000 for married couples filing jointly. These thresholds are not indexed for inflation, so more sellers cross them each year.3Internal Revenue Service. Questions and Answers on the Net Investment Income Tax
Deferring Gain Through a 1031 Exchange
A Section 1031 like-kind exchange lets you defer capital gains and depreciation recapture taxes by reinvesting the proceeds into another qualifying commercial property. The deadlines are strict and absolute. You have 45 days from the closing of your sale to identify potential replacement properties in writing, and 180 days to close on the replacement. These windows run concurrently, not consecutively, and extensions are essentially unavailable.4eCFR. 26 CFR 1.1031(k)-1 – Treatment of Deferred Exchanges You must use a qualified intermediary to hold the sale proceeds. If you touch the money yourself at any point, the exchange fails and the full tax bill comes due.
FIRPTA Withholding
If you’re a foreign person or entity selling U.S. commercial real estate, the buyer is required to withhold 15% of the amount realized and remit it to the IRS under the Foreign Investment in Real Property Tax Act. U.S. sellers avoid this by providing the buyer with a non-foreign affidavit that includes a taxpayer identification number and a statement under penalty of perjury that the seller is not a foreign person.5Office of the Law Revision Counsel. 26 USC 1445 – Withholding of Tax on Dispositions of United States Real Property Interests Don’t skip this. Without the affidavit, the buyer is legally obligated to withhold regardless of your citizenship.
Closing and Transferring Title
Commercial closings are coordinated through a title company or escrow agent acting as a neutral third party. The title company holds the buyer’s funds, confirms that all conditions of the Purchase and Sale Agreement have been met, and prepares the settlement statement. Commercial transactions are exempt from the consumer-oriented TILA-RESPA disclosure rules that govern residential loans, so the closing statement is typically prepared on an ALTA form or a similar settlement sheet rather than the Closing Disclosure used in home sales.6Consumer Financial Protection Bureau. What Is a HUD-1 Settlement Statement? The settlement sheet provides a line-by-line accounting of purchase price, prorated property taxes, transfer taxes, title insurance premiums, and other fees.
Budget for closing costs you may not expect. Transfer taxes vary widely by jurisdiction, from a fraction of a percent to several percent of the sale price depending on state and county. Recording fees for filing the deed are relatively modest but vary by locality. Title insurance, which protects the buyer and their lender against title defects discovered after closing, typically costs anywhere from $2,500 to $15,000 on commercial transactions depending on the property value. Notary fees for executing closing documents are minor.
Ownership officially transfers when the signed deed is recorded with the county clerk or recorder’s office. That public filing puts the world on notice that title has moved from you to the buyer. Once recording is confirmed, the escrow agent wires the net proceeds to your bank account, minus outstanding liens, prorated expenses, and closing costs deducted on the settlement statement.
After the Wire Clears
The wire hitting your account isn’t quite the end. Hand over all physical access tools, security codes, alarm system information, and keys. Send formal written notice to every tenant informing them of the ownership change, identifying the new landlord, and directing future rent payments to the new owner’s designated account. Finalize all utility accounts as of the closing date so you aren’t paying for the buyer’s electricity.
If your Purchase and Sale Agreement included a survival clause for representations and warranties, you remain potentially liable for those statements for the duration of that period. Keep copies of every document you provided during the sale, every disclosure you made, and every communication with the buyer for at least as long as the survival period runs. If a tenant dispute, environmental issue, or financial discrepancy surfaces after closing and falls inside the scope of your representations, those records are what you’ll defend yourself with.
