Commercial property closing costs generally run 2% to 5% of the purchase price for the buyer and 4% to 8% for the seller, with brokerage commissions driving most of the seller’s total and due diligence, financing, and title charges driving the buyer’s. Industrial sites, contaminated land, and deals with layered financing can push either side well past those ranges. The jurisdiction matters as much as the property: transfer tax rules alone can swing the bill by tens of thousands of dollars on the same purchase price.
Who Pays What at a Commercial Closing
Certain costs fall on each side by convention. Buyers pay for their own due diligence (inspections, environmental work, surveys), lender-related charges (origination, appraisal, underwriting), and their share of title insurance. Sellers cover the broker’s commission, their own attorney, any transfer taxes the jurisdiction assigns to them, and payoffs needed to deliver clear title.
Everything else is negotiable in the purchase agreement. A motivated seller might pick up transfer taxes or a portion of the buyer’s title premium; a competing buyer might absorb costs the seller would normally pay. Spell every allocation out in the contract. Assumptions about who pays what are the most common source of closing-day fights in commercial deals.
Buyer Due Diligence Costs
Due diligence is where commercial closings depart sharply from residential ones. A single home inspection on a house becomes half a dozen specialized reports on a commercial purchase, and the buyer pays for nearly all of them.
Environmental Assessments
A Phase I Environmental Site Assessment is the baseline on almost every commercial deal. It covers a records review, site visit, and historical analysis to flag potential contamination, and it establishes the buyer’s “all appropriate inquiries” defense against liability for pre-existing contamination under CERCLA.1U.S. Environmental Protection Agency. Third Party Defenses/Innocent Landowners A straightforward Phase I runs $2,000 to $4,000. Large or historically complex sites can push past $6,000.
If the Phase I identifies recognized environmental conditions, the lender will almost always require a Phase II, which involves soil sampling and groundwater testing. Routine Phase II work costs $6,000 to $25,000. Heavily contaminated sites can exceed $100,000. This is where buyers either commit or walk away.
Property Condition Assessment
A Property Condition Assessment evaluates the building’s structure, roof, mechanical systems, and remaining useful life on major components. Reports typically run $1,500 to $4,000 based on size and age. Lenders rely on them to flag immediate capital repairs that would affect the property’s value as collateral.
ALTA Survey
An ALTA/NSPS Land Title Survey maps boundaries, easements, encroachments, and access points in the format title companies require for commercial insurance. Basic surveys on small lots start around $3,000. Standard commercial properties commonly run $8,000 to $15,000. Large or irregular parcels with multiple access points can hit $25,000 or more. Cutting corners here invites boundary disputes and undisclosed easements that surface after closing.
Zoning Compliance
A zoning compliance report confirms that the current use is legally permitted and flags nonconforming uses or setback violations that could block the buyer’s plans. These typically cost $500 to $700 for a single-site review, plus the municipality’s own verification letter fee.
Lender and Financing Fees
Financing generates its own layer of costs, separate from anything tied to the physical building.
Origination, Underwriting, and Processing
Loan origination fees on commercial mortgages generally run 0.5% to 1% of the loan amount, with some lenders and private capital charging up to 2% on higher-risk or smaller loans. On a $2 million loan, that is $10,000 to $40,000 at the high end. Underwriting and processing fees cover the lender’s internal work and may be bundled into origination or billed separately.
Appraisal and Lender’s Attorney
Commercial appraisals analyze comparable sales, income capitalization, and replacement cost, and often run past 100 pages. Fees range $3,000 to $10,000 depending on property type, with hotels, medical facilities, and industrial plants costing more. The lender also hires its own attorney to draft loan documents, review title, and prepare security instruments. Those fees start around $2,000 for simple deals and climb quickly when the financing involves multiple tranches, mezzanine debt, or complex guaranty structures. The borrower pays, even though the lender picks the lawyer.
SBA 504 Loan Fees
Owner-occupied purchases financed through the SBA 504 program carry additional fees. For fiscal year 2026 (loans approved October 1, 2025, through September 30, 2026), the upfront guaranty fee is 0.50% of the loan amount, with an ongoing annual service fee of about 0.21% of the outstanding balance.2U.S. Small Business Administration. SBA Waives Loan Fees for Small Manufacturers in Fiscal Year 2026 Manufacturers classified under NAICS sectors 31 through 33 get both fees waived for that period. The Certified Development Company handling the loan also charges its own processing and closing fees.
Title, Escrow, and Attorney Fees
Commercial transactions usually involve two title policies: a lender’s policy required by the bank, and an owner’s policy protecting the buyer. Premiums are a percentage of the purchase price, and rates vary by state. Some states regulate the premium, others leave it to the market. As a rough benchmark, combined policies often fall in the 0.5% to 1% range of the purchase price, though high-value deals in regulated states can see lower effective rates on the incremental value above certain thresholds.
Escrow and settlement agents typically charge $1,000 to $2,500 for managing documents and funds. A closing attorney reviewing the deed, loan documents, and ancillary agreements commonly bills $1,500 to $5,000 as a flat fee, with hourly billing on larger transactions pushing higher.
Transfer Taxes and Recording Fees
Transfer taxes are the most jurisdiction-dependent line on the settlement statement. About 16 states impose no state-level transfer tax at all. Others charge rates up to 3% of the sale price, and some states and cities stack local surcharges that push the combined burden past 5% in the most expensive markets. A handful of states use flat fees. On a $2 million property in a state charging $2 per $1,000 of value, the transfer tax is $4,000. The same property in a high-tax city could owe $40,000 or more. Budget off the specific jurisdiction, not a national average.
Recording fees cover filing the deed, mortgage, and other closing documents with the county recorder. Some counties charge a flat fee per document, others charge per page, and many add supplemental fees for fraud prevention or document preservation. A standard commercial closing involves multiple recorded documents and total recording costs usually land between $200 and $1,000.
Prorations and Lender Reserves
Prorations split ongoing expenses between buyer and seller based on the closing date. They do not add net cost to the deal, but they move real cash at closing. Property taxes are usually the largest. The seller is responsible through the day before closing, the buyer picks up the rest, and because the current year’s bill is often not finalized at closing, the proration is calculated off the prior year with a true-up provision in the purchase agreement.
On income-producing properties, rent is prorated and tenant security deposits must be transferred to the buyer at closing, since the buyer inherits the obligation to return them. Utility deposits, prepaid insurance, and CAM charges may also prorate depending on the contract.
Commercial lenders also frequently require the buyer to fund reserve accounts at closing, which can add tens of thousands of dollars to the cash needed on closing day. Typical reserves include a replacement reserve for future capital expenditures, a tax and insurance escrow pre-funded to cover upcoming bills, and sometimes a deferred maintenance reserve if the Property Condition Assessment flagged near-term repairs.3Fannie Mae Multifamily Guide. Replacement Reserve These deposits are not fees; the buyer keeps ownership of the funds. But the money is locked up with the lender until the loan is paid off, and it has to be accounted for in the closing budget.
Tax Treatment of What You Pay
Not every closing cost hits your return the same way. The IRS separates costs that increase your property’s tax basis from costs tied to getting the loan.
Costs added to basis include transfer taxes, recording fees, owner’s title insurance, survey fees, legal fees for the purchase itself, and abstract of title fees.4Internal Revenue Service. Publication 551 – Basis of Assets A higher basis reduces taxable gain when you sell later, but gives no deduction now.
Loan-related costs follow different rules. Points and loan origination fees on business property are deductible, but spread over the loan term rather than taken in the year of purchase.4Internal Revenue Service. Publication 551 – Basis of Assets Lender-required appraisal fees and credit report costs are capitalized as costs of getting the loan and deducted over the loan’s life. Mortgage insurance premiums are deductible as a business expense.
Property taxes the seller owed that you agreed to pay as part of the deal get added to basis rather than deducted as taxes, a distinction that trips up buyers who assume every property tax payment is immediately deductible.4Internal Revenue Service. Publication 551 – Basis of Assets Amounts placed in escrow for future tax and insurance payments are not deductible until the escrow actually disburses them.
FIRPTA Withholding When the Seller Is Foreign
One cost sits outside the usual framework. If the seller is a foreign person or entity, the buyer must withhold 15% of the total amount realized on the sale and remit it to the IRS under FIRPTA.5Office of the Law Revision Counsel. 26 USC 1445 – Withholding of Tax on Dispositions of United States Real Property Interests On a $3 million property, that is $450,000 held back from the seller’s proceeds. Foreign corporations distributing U.S. real property interests face a 21% withholding rate on the gain recognized.6Internal Revenue Service. FIRPTA Withholding
The seller can apply to the IRS for a withholding certificate to reduce the amount if the actual tax liability will be lower, but the application takes time and must be started well before closing. The closing attorney or title company handles the mechanics, but a buyer who fails to withhold can be held personally liable for the tax. Verify the seller’s status early.
