More of the business owners and investors I talk with in Orange County are asking the same thing this year: should I stop paying rent and buy the building? Commercial property works very differently from buying a home, from the loan to the contract to the math that decides whether a deal is good. Here are the five questions I hear most, answered with real 2026 numbers.
How much do you need to put down to buy a commercial property?
Plan on 10 percent down if you are buying a building for your own business with an SBA 504 loan, and roughly 25 to 35 percent down for a conventional commercial or investment loan. The gap between those two numbers is the single biggest reason owner-users should look at SBA financing first.
Under the SBA 504 program, a standard building such as a warehouse, office condo or retail storefront typically needs 10 percent down. That rises to 15 percent if your business is under two years old or the property is special purpose (think a car wash, hotel or gas station), and to 20 percent if both apply. Investors buying a property to lease out cannot use SBA loans, so they go conventional, where lenders usually cap the loan at 65 to 75 percent of value and also test the income. Most commercial lenders want the net operating income to cover the mortgage payment by about 1.20 to 1.25 times. On top of the down payment, budget for closing costs, the Orange County transfer tax of 1.10 dollars per 1,000 dollars of price, reports like an appraisal and environmental study, and reserves.
Can I use an SBA loan to buy a building for my business?
Yes, as long as your business will occupy at least 51 percent of an existing building (60 percent for new construction) and meets SBA size standards. The SBA 504 loan is built for exactly this, and it offers long fixed-rate terms that conventional commercial loans rarely match.
A 504 deal is split into three pieces: about 50 percent from a bank first mortgage, up to 40 percent from a Certified Development Company (CDC) backed by the SBA, and your 10 percent down. On a 2 million dollar Irvine or Tustin industrial condo, that looks like 200,000 dollars from you, 1 million from the bank and 800,000 from the CDC. The SBA portion can go up to 5.5 million dollars, with 10, 20 or 25 year terms. For September 2026, the 25 year 504 debenture priced at an effective rate of about 6.54 percent, fixed for the life of the loan. The bank portion carries its own rate and terms, so shop it. You can also use the extra space: if you occupy 51 percent, you can lease the rest to a tenant to help cover the payment. The SBA 7(a) loan is the other option, often with 10 percent down as well, and it can bundle the building with equipment or a business purchase.
Is it better to buy or lease a commercial building for my business?
Buying usually wins if you plan to stay at least 7 to 10 years, your business is stable, and you can put down 10 percent without draining working capital. Leasing wins if you are growing fast, might relocate, or need that cash in the business.
Here is how rent looks right now. In the second quarter of 2026, Orange County industrial space averaged about 1.45 dollars per square foot per month on a triple net basis, according to Kidder Mathews. For a 5,000 square foot shop in Anaheim or Santa Ana, that is roughly 7,250 dollars a month, or 87,000 dollars a year, before your share of taxes, insurance and maintenance, and most leases raise that rent every year. Owning locks your largest cost into a fixed payment, lets you build equity, and gives you depreciation and interest deductions to review with your CPA. The tradeoffs are real too: you carry the roof, the HVAC and the vacancy risk, and your cash is tied up in the building. One Orange County specific point: Prop 13 still applies to commercial property, so your property tax is reset to your purchase price when you buy and then limited to 2 percent increases per year after that, which makes your long term costs predictable.
What is a good cap rate for commercial property in Orange County?
In Orange County, cap rates are low compared to most of the country. Retail averaged about 5.4 percent in the second quarter of 2026, according to Kidder Mathews, with an average sale price around 522 dollars per square foot. Anything meaningfully above the market average usually signals more risk, a weaker tenant or deferred work, so find out why before you get excited.
A cap rate is the property's net operating income divided by its price. A building earning 108,000 dollars a year in net income and priced at 2 million dollars is a 5.4 percent cap. The number that matters most for investors right now is how the cap rate compares to your borrowing cost. With commercial loan rates in the mid 6 percent range, a 5.4 percent cap rate means borrowed money costs more than the building earns on it. That is called negative leverage, and it means your cash return falls the more you borrow. Orange County buyers accept lower cap rates because vacancy is tight (retail was about 3.2 percent in Q2 2026) and values have historically held up. Office is the exception to watch, with direct vacancy near 10.9 percent in Q2 2026, so office deals need extra care on tenant quality and lease length.
What due diligence should you do before buying a commercial property?
Use the due diligence period, usually 15 to 45 days in a commercial purchase, to confirm the building, the income, the environmental history and the zoning before your deposit goes hard. Once that period ends, walking away usually means losing your deposit.
Here is the checklist I walk every buyer through. First, a building inspection covering the roof, HVAC, electrical, plumbing and structure, plus compliance items like fire systems and ADA accessibility, which matters a lot in California. Second, a Phase I Environmental Site Assessment, which most lenders require and which typically runs about 2,500 to 6,750 dollars in California in 2026 with two to three weeks of turnaround. If it finds a problem, you negotiate or order a Phase II with actual soil testing. Third, the money: every lease, rent payment records, tax returns and operating bills, checked against what was marketed, plus signed estoppel certificates from tenants confirming their rent and terms. Fourth, zoning. Call the city planning department in Irvine, Costa Mesa or wherever the property sits and confirm your use is allowed, even if the last owner ran the same kind of business. Finally, if you are buying through an LLC or buying an interest in an entity that owns California property, you may need to file form BOE-100-B with the State Board of Equalization within 90 days to avoid a penalty. In Orange County, most commercial deals are written on AIR CRE forms, which spell out exactly what the seller must deliver and when.
Buying your first commercial building is one of the biggest moves a business owner or investor makes, and the details decide whether it pays off.
