What Is a CMBS Conduit Loan?
Think of a conduit as a big pipe. Lots of small commercial mortgages go in one end. They get bundled together, and a bond—called a Commercial Mortgage-Backed Security (CMBS)—comes out the other end.
These are not bank loans. A bank holds your loan on its books. A conduit lender originates your loan just to sell it into that big pipe. Because of this, the rules are very strict and standard.
How Do These Loans Look?
Conduit loans are famously predictable. You know exactly what you’re getting: a long term, a fixed rate, and no personal guarantee hanging over your head. You lock in the payment and forget about it, at least until maturity.
But the flexibility is zero. You can’t just pay it off early without a penalty. The trade-off is simple: give up flexibility, get a lower rate and no personal risk.
The goal is to create a boring, predictable bond that pension funds want to buy. The lender follows rigid rules to make sure your loan cash flow matches what bond investors expect.
If you hate surprises, this product might be for you.
| Feature | CMBS Conduit Loan | Traditional Bank Loan |
|---|---|---|
| Recourse | Usually non-recourse | Often full or partial recourse |
| Rate Type | Fixed (5 to 10 years) | Often floating or shorter fixed |
| Prepayment | Locked out or expensive yield maintenance | Usually allowed with small fee |
| Amortization | Often 30 years | Typically 20 to 25 years |
| Underwriting | Cash flow focus (DSCR) | Relationship and cash flow focus |
A real estate investor buys a boring strip mall for $5 million. A local bank offers a 5-year loan with a floating rate. A conduit lender offers a 10-year fixed rate at 5.5%. The investor takes the conduit loan. He sleeps better at night knowing the payment won’t change.
The Big Three Numbers Lenders Watch
When you apply for a conduit loan, the underwriter opens a spreadsheet. They are staring at three main numbers. If these numbers don’t hit the mark, the deal is dead before it starts.
It doesn’t matter how nice the building looks. It’s a math problem. You need the cash flow to cover the new debt, you need skin in the game, and the property needs to pay for itself with room to spare.
| Metric | Standard Threshold (2025) | Why It Matters |
|---|---|---|
| DSCR (Debt Service Coverage Ratio) | Usually 1.25x minimum | Shows if income covers the mortgage payment. Higher is safer. |
| LTV (Loan-to-Value) | Typically 65% or lower | Limits how much you can borrow. Protects the lender if you default. |
| Debt Yield | Often 10% or higher | Net income divided by loan amount. An extra safety net for lenders. |
Digging Into DSCR and Debt Yield
DSCR is simple: take your net operating income (NOI) and divide it by your total yearly mortgage payment. If the number is 1.25, you have 25% more cash than you need to pay the mortgage. That buffer is what the bond market demands.
Debt yield is even more strict. It tells the lender how fast they get their money back if they have to take the keys tomorrow. It ignores interest rates completely. A low debt yield means the loan is too big, no matter how much cash flow you have today.
Conduit lenders don’t care about your personal income. Your tax returns barely matter.
It’s all about the property’s operating statement. If the rent roll is strong and expenses are normal, you have a shot.
| Property Type | Typical Min DSCR | Reasoning |
|---|---|---|
| Multifamily (Apartments) | 1.20x – 1.25x | Stable demand, easy to model |
| Industrial / Warehouse | 1.20x – 1.25x | Strong sector performance |
| Retail (Strip Mall) | 1.30x or higher | Higher risk of tenant turnover |
| Office | 1.35x or higher | High vacancy risk post-Covid |
| Hotel (Hospitality) | 1.40x – 1.50x | Daily lease risk, volatile cash flow |
An office building has a strong NOI of $500,000. The requested loan payment is $400,000 per year. That’s a 1.25x DSCR. Sounds okay, right? Not to a conduit lender in 2025. They worry about companies downsizing office space. They demand a 1.35x DSCR. The buyer has to put up more cash to bring the loan payment down.
The Lockout and Defeasance Puzzle
You cannot just sell the property and pay off the loan on day one. Conduit loans have a mechanism called defeasance. It sounds scary, but it’s just a swap. You keep paying the loan, but you swap the collateral.
You buy a basket of government bonds. Those bonds make the payments for you. The lender gets paid exactly the same amount on the exact same days. Then you can sell the property free and clear.
| Period | Option | Cost to Borrower |
|---|---|---|
| Year 1 to Year 2 | Fully Locked Out | No exit allowed |
| Year 3 until 90 days before maturity | Defeasance or Yield Maintenance | Cost of buying Treasury bonds (decreased rates = higher cost) |
| Last 90 days | Open Period | Small administrative fee, full payoff allowed |
If rates have gone down since you got your loan, defeasance is expensive. You are paying for high-rate bonds to replace your high-rate loan. If rates have gone up, you actually make money. The bonds are cheap, but you still get to pay off the loan.
A borrower had a 6% fixed rate loan. Rates dropped to 4%. He wanted to sell. To defease, he had to buy bonds yielding 4% to cover the 6% payments. It cost him a fortune. He decided to hold the property until the open period.
Reserves and Escrows Are Non-Negotiable
Bank loans can be casual about taxes and insurance. You might pay them yourself. In the conduit world, that doesn’t fly. Lenders want control. They sweep your cash every month to pay taxes and insurance for you.
They also hold back money for repairs. It’s called a replacement reserve. It doesn’t matter if the roof is brand new. They take a little bit of your cash flow every month, just in case. This protects the bond investors from surprise repair costs destroying the cash flow.
A Master Servicer and a Special Servicer watch your loan. If you miss a payment, the Special Servicer takes over. They can make big decisions—like foreclosing—based on what’s best for the bond holders, not you.
You are dealing with a computer system and a legal contract, not a friendly local banker.
| Escrow Type | Typical Monthly Collection | Purpose |
|---|---|---|
| Real Estate Taxes | 1/12 of annual bill | Prevent tax lien foreclosure |
| Property Insurance | 1/12 of premium | Ensure asset is covered |
| Replacement Reserves | $250 - $400 per unit (Multifamily) | Fund future capital repairs |
| Tenant Improvement Reserves | Negotiated per lease | Cover future leasing commissions |
The servicer pulls this money out of your account automatically. The cash you see at the end of the month is the cash you can actually spend. This is why in-place cash flow is what matters, not just the paper profit.
An owner bought a building thinking the NOI was $100,000. He forgot that the lender would scoop $15,000 a year for taxes, insurance, and reserves into a locked box. His actual spendable cash was $85,000. He had to adjust his lifestyle fast.
Key Takeaways
