Picture two business owners who apply for a $2 million loan in the same week. Same city, same bank, even the same loan officer. One walks away with a quote that’s comfortably competitive. The other gets a rate nearly two points higher and spends the drive home wondering what he did wrong.
Probably nothing. At least, nothing personal.
You see, an interest rate isn’t a reward or a punishment. It’s a price tag on risk. Every lender, from the biggest national bank to the smallest private fund, is quietly asking the same two questions about your deal. How likely am I to get my money back? And how painful will it be if I don’t? The answer shows up, to the decimal point, in the rate you’re offered.
Once you understand how the math works, the quotes on your desk start making a lot more sense. You also gain some real leverage over them. So let’s pull back the curtain.
Every Rate Starts With the Same Two Ingredients
Nearly every commercial loan rate is built from two parts: a base rate and a spread.
The base rate (often called the index) is the lender’s starting point. It reflects what money costs in the broader market. Common ones include the prime rate, Treasury yields (the 5- and 10-year are popular for fixed-rate real estate loans), and SOFR, the Secured Overnight Financing Rate, which the New York Fed publishes every business day.
You don’t control the index. Neither does anyone at the bank.
The spread is the markup the lender adds on top. It covers their operating costs and profit margin. More importantly, it covers the risk they believe they’re taking on your particular deal. Lenders talk in basis points, and 100 basis points equals one percentage point. If the 10-year Treasury sits at 4% and a lender quotes “Treasury plus 225,” you’re looking at 6.25%.
So when two borrowers get different rates on the same day, the index isn’t the reason. The spread is.
What the Spread Is Really Measuring
Underwriters think about risk in two layers.
First, how likely is it that this loan goes bad?
Second, if it does, how much money will they actually lose?
A loan with a low chance of default and a strong fallback position earns a thin spread. But if the lender has doubts on either of those two questions, the spread gets wider, increasing your interest rate.
Simple as that.
The kind of lender you work with, the way it sizes up your deal, and the collateral you put up all come back to those same two questions. Once you analyze a lender through that lens, almost every number on a term sheet starts to make sense.
Different Lenders, Different Appetites
Not all loan money comes from the same place. A lender’s own cost of capital, its regulators, and its tolerance for risk all shape the rates it can offer. Here’s a rough tour, starting with the typically cheapest money and working toward the most expensive:
• Agency lenders (Fannie Mae and Freddie Mac) focus on multifamily housing. Their government sponsorship keeps pricing sharp on apartment deals.
• Banks and credit unions fund loans largely with deposits, which is inexpensive money. They tend to price well, especially for borrowers who bring deposits along, but regulators keep them on the conservative side.
• SBA lenders make loans partially guaranteed by the U.S. Small Business Administration. That guarantee shrinks the lender’s potential loss, and the SBA also limits how far above the base rate lenders can go.
• CMBS lenders bundle loans and sell them to bond investors. Pricing follows the bond market, and the terms tend to be more rigid once the loan closes.
• Debt funds and bridge lenders use investor capital that expects higher returns. They’ll finance transitional deals a bank won’t touch, but at a higher cost.
• Private and hard money lenders sit at the far end. They move fast, focus mostly on the asset, and charge accordingly.
See the pattern? The lenders with the cheapest money tend to have the strictest requirements. In fact, the two go hand in hand. They can afford to charge less because they only take on the safest deals. As you move toward lenders willing to accept more risk, such as bridge and private lenders, the requirements loosen up and the rates rise to match. So if your deal doesn’t qualify with one type of lender, that doesn’t make it a bad deal. More often, it just means the deal is a better fit for a different kind of lender.
How Underwriters Decide Whether You’ll Pay Them Back
Once a deal lands on an underwriter’s desk, it gets sized up in a few different ways. Which approach a lender leans on tells you a lot about how it will price.
Cash flow comes first for most lenders
Banks, SBA lenders, and most long-term real estate lenders are cash-flow lenders. Their main concern is whether the business or property earns enough to cover the loan payments with room to spare. The key metric here is the debt service coverage ratio, or DSCR. It’s simply net operating income divided by the annual loan payments.
Say a property produces $150,000 a year in net operating income and the loan payments total $120,000. That’s a DSCR of 1.25, meaning there’s a 25% cushion between what comes in and what goes out. Many lenders treat 1.20 or 1.25 as a floor. Push that number up toward 1.50 and you’ll often see the spread tighten, because the odds of a missed payment drop considerably.
Some lenders look at the asset first
Hard money and many bridge lenders flip the script. They care less about today’s income and more about what the collateral is worth, and how quickly they could sell it if something went sideways. That’s why they can close on a vacant building or a fix-and-flip. It’s also why they charge more. The lender’s first line of defense, steady cash flow, is thin or missing entirely.
And almost everyone looks at you
Nearly every lender also underwrites the people behind the deal. They’ll review credit history, net worth, liquidity (actual cash and near-cash you could tap in a pinch), and experience. A developer on her tenth ground-up project reads very differently than someone attempting a first one.
For operating businesses, many lenders also run a global cash flow analysis. That rolls the company’s income together with the owners’ personal income and debts, so the lender can see the whole financial picture rather than one slice of it. A strong sponsor can offset a slightly weaker deal. Unfortunately, the reverse is true too.
Collateral: The Lender’s Plan B
Cash flow answers “how likely is a default?” and collateral answers “how bad would it be?” A few factors carry most of the weight here.
Loan-to-value (LTV) is the big one. It’s the loan amount divided by the collateral’s appraised value. At 60% LTV, a property’s value could fall 40% before the lender’s principal is at risk. At 80%, that cushion shrinks to 20%. Lower leverage almost always means better pricing, and it’s one of the few levers you directly control.
Property and asset type matters as well. Lenders generally view multifamily and industrial as steady performers, while hotels, special-use properties like car washes or event venues, and certain office buildings carry more perceived risk. Business assets such as equipment, inventory, and receivables tend to lose value faster than real estate and can be harder to sell, so loans secured mainly by them usually cost more.
Then there’s lien position. A first lien gets paid first if things go wrong. A second mortgage waits in line behind it. A mezzanine loan, secured by the ownership interest rather than the property, sits further back still. That’s why those rates run noticeably higher.
Finally, recourse. A full-recourse loan lets the lender pursue the guarantor personally if the collateral falls short. A non-recourse loan limits the lender to the property itself. It’s a trade-off. Non-recourse protects you, but you’ll usually pay for that protection through lower leverage, stricter underwriting, or tougher prepayment terms, and sometimes a higher rate.
The Fine Print That Changes Rates
Beyond risk, a handful of structural choices shift your rate too. Sometimes more than borrowers expect.
Longer fixed-rate terms usually cost a little more, since the lender is locking in and absorbing more uncertainty about where rates are headed. Floating rates can start lower but move with the market. Prepayment penalties, oddly enough, can work in your favor on price: a loan you agree not to pay off early is worth more to the lender, so stiffer prepayment terms can buy a lower rate. Interest-only periods and longer amortization schedules ease your monthly payment but increase the lender’s exposure, which can nudge the spread up.
Loan size plays a part. A $400,000 loan takes nearly as much work to underwrite as a $4 million one, so smaller loans sometimes carry a wider spread to make the effort worthwhile. And relationships count. Banks in particular will often sharpen their pencil for a borrower who moves operating accounts and deposits over.
Putting It All Together
Let’s go back to those two business owners from the beginning.
The first is buying a stabilized, fully leased industrial building. She’s putting 35% down, the property covers its loan payments 1.6 times over, and she’s owned similar buildings for fifteen years. Low odds of default, a big equity cushion, a proven operator. Her spread is thin, and it should be.
The second is buying a partially vacant retail center with 20% down. His DSCR to start hovers around 1.10, and his plan is to lease the space up over the next two years. Nothing about that plan is unreasonable. But nearly every factor above points toward more risk, and his quote reflects it. He might be better served by a bridge loan now and a permanent loan once the center is stabilized.
Same loan amount. Same week. Completely different risk profiles, and completely logical pricing.
Why the Right Lender Matters More Than the Lowest Advertised Rate
Here’s what all of this adds up to. Your best rate isn’t found by chasing the lowest number you see online. It comes from matching your deal to the lender whose appetite genuinely fits it, and then presenting the deal so the risk looks clear and manageable.
That’s a big part of what a good commercial loan brokerage does. An experienced advisor knows which lenders are actively competing for your property type and loan size right now, and which ones will politely pass. They know how to package a deal so an underwriter sees the strengths up front: the sponsor’s track record, realistic cash flow projections, the story behind a vacancy. And they can often spot structural trade-offs, like a bit more equity, a different prepayment option, or a shorter term, that shave real dollars off your cost of capital.
