I had a borrower sit across from me a few months back, a guy who’d just sold a piece of land and was ready to buy a small strip retail building. He said, “I already got pre-approved,” and slid over a letter. It was a pre-approval letter. For a home. His personal mortgage pre-approval from two years earlier, still in his glovebox, because in his mind pre-approval was pre-approval.
I had to explain something most people never get told until they’re already mid-deal: commercial pre-approval isn’t the same animal as residential pre-approval, and walking into a commercial purchase with the wrong kind of paperwork in hand can cost you the deal.
What Pre-Approval Actually Means for a Commercial Loan
With a residential mortgage, the bank is mostly underwriting you: your income, your credit, your personal debt-to-income ratio. Commercial lending flips that around. In most cases, the lender is underwriting the property first: does the building’s income (or projected income) cover the debt payment, with room to spare?
That’s where DSCR (debt service coverage ratio) comes into the conversation. It’s a simple idea even though the name sounds complicated: take the property’s net operating income and divide it by the annual loan payment. A ratio above 1.0 means the property produces more income than it costs to finance; most lenders want to see some cushion above that before they’ll commit. So a “pre-approval” for a commercial deal often means the lender has looked at the property’s numbers, not just yours. That’s exactly why my borrower’s residential pre-approval letter didn’t carry over.
How to Get a Loan for Commercial Property: Step by Step
Here’s roughly how the process actually goes, start to finish:
- Figure out the property type and use. Owner-occupied, multi-tenant, mixed-use, industrial: the lender pool and underwriting approach shifts depending on what you’re buying and whether you’ll occupy any of it yourself.
- Get the property’s financials together. Rent rolls, lease terms, operating expenses, and (if it’s owner-occupied or a new build) a realistic income projection. This is the paperwork that replaces a residential pre-approval’s pay stubs and W-2s.
- Run the DSCR math with a lender. This is the step that actually produces a real pre-approval, not a guess, an actual number based on the property’s income against the proposed loan payment.
- Get pre-qualified on the borrower side too. Even though the property carries more of the underwriting weight, your credit and experience as an investor or operator still matter, especially for loan pricing and down payment requirements.
- Line up your down payment and reserves. Commercial down payments run meaningfully higher than residential, often somewhere in the 20-30%+ range depending on property type and lender, though this varies a lot deal to deal. Reserves matter here too, arguably more than on a residential purchase, since commercial properties don’t have the same safety net options a primary residence does.
Once those pieces are in place, you have something you can actually hand a seller: a real, property-grounded pre-approval instead of a piece of paper that doesn’t apply to what you’re buying.
How Long Does It Actually Take?
This is one of the most common questions I get, and the honest answer is: longer than a residential pre-approval, usually. Because the lender is underwriting the property’s financials and not just running your credit, expect the process to take more back-and-forth: collecting rent rolls, verifying lease terms, sometimes ordering a property-specific analysis before the lender will commit to numbers. It’s not unusual for a real commercial pre-approval to take meaningfully longer than the same-day or 24-hour turnaround people are used to on the residential side. Building in that extra runway before you start making offers saves a lot of stress later.
Can You Use a DSCR Loan for Commercial Property?
Sometimes, depending on the property and the deal. DSCR loans were built around exactly the income-first underwriting approach commercial buyers need, which makes them a natural fit for certain commercial and mixed-use purchases, particularly smaller multi-tenant or investment-oriented properties. If you want to see roughly where your numbers land before you talk to anyone, our DSCR calculator is a good first gut-check: plug in the property’s projected income and a loan amount and see what ratio comes back.
What About FHA or Conventional Loans for Commercial Property?
Short answer: usually not the right tool. FHA and standard conventional financing are built around residential, owner-occupied properties. A straight commercial building, retail space, or industrial property generally falls outside what those programs are designed to finance. I bring this up because I get asked it a lot, usually from someone who’s used FHA before for a home purchase and assumes it carries over.
For actual commercial purchases, the more common paths are commercial loans built specifically for the property type, SBA loans if you’re an owner-operator buying the building your business runs out of, or in some situations hard money financing if you need to move fast or the deal doesn’t fit a conventional underwriting box. Which one actually fits depends entirely on the deal. This isn’t a one-size answer.
Financing a Commercial or Rental Property
If what you’re actually buying is a rental or investment property rather than a straight commercial building, that’s its own conversation, and often a more flexible one. Investment property loans cover a wider range of scenarios than pure commercial financing, and depending on the property, a DSCR-based approach can sometimes get you to closing faster with less personal-income documentation than a traditional path would require.
A Story From My Files
I worked with an investor who found a small mixed-use building (retail on the ground floor, two apartments above) and wanted to move fast because another buyer was circling. She didn’t have a commercial pre-approval yet, just a strong sense of what she could afford based on her personal finances. We pulled the rent roll from the listing, ran the DSCR math same day, and had a real number in hand before her offer went in. It wasn’t a guarantee (final underwriting still needed the full picture), but it was enough to make her offer credible instead of speculative. That’s the entire point of doing this step properly: a seller can tell the difference between a buyer who’s guessing and a buyer who’s already done the math.
What I’d Tell You If You Walked Into My Office Today
If you’re planning to buy anything other than a straight primary residence, don’t assume your last pre-approval letter travels with you. Commercial and investment property financing runs on different math (the property’s income, not just your paycheck), and getting that math done before you’re under a deadline is what separates a smooth close from a scramble.
Start by getting a real sense of the property’s numbers, not just your own. If you want a starting point, begin pre-qualification and we’ll figure out which path (DSCR, commercial, SBA, or otherwise) actually fits what you’re buying.
