Most business owners approach a commercial loan the same way they approached their first car loan: show up, hand over some paperwork, and hope for a yes. Commercial lenders do not work that way. Understanding what they actually care about changes how you prepare and dramatically improves your odds of approval at a rate you can live with.
Commercial lending is relationship-driven and judgment-heavy. There is no algorithm spitting out an instant decision. A loan officer is building a case to present to a credit committee, and your job is to make that case as easy to approve as possible. That means knowing the five factors every commercial lender weighs before saying yes.
1. Debt Service Coverage Ratio (DSCR)
This is the number one metric in commercial lending. DSCR measures how much cash flow your business generates relative to the loan payments you are taking on. The formula is simple: divide your net operating income by your annual debt service (principal plus interest).
Most commercial lenders require a minimum DSCR of 1.25. That means for every $1.00 in annual loan payments, you need to show $1.25 in business income. A DSCR below 1.0 means your business cannot cover the payments, which leads to an instant decline. A DSCR of 1.35 or higher puts you in a favorable position and may earn better pricing.
Before you apply, calculate this yourself. Take your business's net income from the last two to three years, add back non-cash expenses like depreciation and amortization, then divide by what your projected annual loan payment will be. If the number is below 1.25, focus first on improving profitability or reducing existing debt before you apply.
2. Loan-to-Value Ratio (LTV)
LTV is the loan amount divided by the appraised value of the property. On a conventional commercial mortgage, most lenders cap LTV at 75%, meaning you need at least 25% down. Some community banks go to 80% for strong borrowers. SBA 504 loans allow up to 90% LTV, which is why they are so powerful for business owners who want to preserve working capital.
What many borrowers do not realize is that the lender orders their own appraisal, and that appraisal may come in lower than your agreed purchase price. If you are paying $1.2 million for a building that appraises at $1.1 million, the lender will base their LTV calculation on $1.1 million. Your down payment suddenly has to cover the gap plus the required equity percentage. Build this possibility into your financial planning before you go under contract.
3. Global Cash Flow
Commercial lenders do not look at your business in isolation. They look at the complete financial picture of you and any related entities, what they call global cash flow. This includes your personal income, any other businesses you own, real estate you already hold, and any guarantors on the loan.
If you own multiple businesses, the lender will want tax returns and financial statements for all of them. If one business is struggling, it drags down the global picture even if the primary business is strong. This is also why the OpCo/PropCo structure matters: separating your operating company from your property company gives lenders a cleaner view of each entity and can strengthen your overall credit presentation.
4. Property Characteristics and Owner-Occupancy
Lenders care deeply about the property itself, not just your financials. They want to know: What is the property type? What is its condition? Is it in a strong or declining market? How liquid is this asset if they ever have to sell it?
Here is where being an owner-occupant works strongly in your favor. A lender financing a pure investment property has to worry about vacancy and tenant risk on top of your creditworthiness. When you are buying the building for your own business operations, the lender knows you have a direct incentive to keep the business healthy, keep the building occupied, and keep making payments. Owner-occupancy typically earns you better underwriting treatment and often a lower rate than investor financing.
Properties that lenders favor: standard retail, office, light industrial, medical office, flex warehouse. Properties that lenders approach with caution: restaurants, gas stations, car washes, and other single-use facilities with limited re-use potential. Know where your target property fits before you apply.
5. Personal Credit and Guaranty
Unlike residential mortgages, commercial loans almost always require a personal guaranty from the principal owners, typically anyone with 20% or more ownership. That means if the business defaults, you are personally on the hook. Lenders know this aligns your incentives perfectly, which is partly why they require it.
Your personal credit score matters, but it is not as dominant a factor as in residential lending. Most commercial lenders want to see 680 or above, but a score of 720+ will not necessarily get you a dramatically better rate the way it might on a home mortgage. What matters more is the overall credit picture: no recent bankruptcies, no pattern of late payments, no large unexplained derogatory marks. If there are issues in your credit history, get ahead of them by preparing a written explanation before you sit down with a lender.
How to Walk In Ready
The business owners who get the best commercial loan terms are not the ones with the most money. They are the ones who show up organized. Prepare a complete loan package before your first meeting: three years of business tax returns, three years of personal tax returns, year-to-date financials, a personal financial statement, a rent roll if the property has existing tenants, an executive summary of your business and why you are buying this building, and a written explanation of any credit issues.
Shopping multiple lenders also matters. Community banks, credit unions, regional banks, and SBA-preferred lenders all have different appetites and pricing. A community bank that specializes in your industry may be far more aggressive on rate and terms than a national bank that treats your file as just another number. Get at least three competing quotes before committing. Use the rent vs. buy calculator to model the impact of different rate scenarios on your long-term economics before you finalize anything.

The Bottom Line
Commercial lenders are not looking for reasons to say no. They are looking for reasons to say yes. When you walk in having already calculated your DSCR, understanding your LTV position, and organized your global financials into a clean package, you are making their job easy. That preparation signals that you are a serious, competent borrower, exactly the kind of person they want to lend to for the next 20 years.
The business owner who does this homework does not just get approved. They get approved faster, at better terms, and with a lender who is genuinely invested in their success. That relationship has value far beyond the closing table.
