CMBS vs Life Insurance Company vs Debt Fund: Which Lender Fits Your Net Lease Deal?

TL;DR

Four lender types dominate net lease financing, each with a different profile. CMBS is the workhorse for high-leverage, non-recourse, long-term fixed-rate financing — but carries defeasance lockouts that limit flexibility. Life insurance companies offer lower leverage and conservative terms in exchange for the most attractive pricing on stabilized investment-grade properties, often with yield-maintenance prepayment. Debt funds trade higher leverage and structural flexibility for higher cost — their sweet spot is transitional or value-add deals, or situations banks and life cos won't touch. Banks remain active in the space but typically require recourse and are most interested in relationship-driven portfolio lending. This post walks through each one's structural features and where each actually wins.

The Four Main Capital Sources

1. CMBS (Commercial Mortgage-Backed Securities)

CMBS loans are originated by investment banks and specialty lenders, then packaged into bond pools and sold to institutional investors. The originator is typically an arm of a large bank (Morgan Stanley, JPMorgan, Wells Fargo, Goldman Sachs, etc.) or a specialty shop (Ladder Capital, Starwood Property Trust's CMBS arm, Greystone, etc.).

Key features:

• Non-recourse (standard) — the property is the only security for the loan; the borrower isn't personally liable outside of "bad boy" carveouts (fraud, environmental liability, intentional misrepresentation)
• Fixed rate for the full loan term (typically 10 years)
• Interest-only or IO + amortization structures common
• Defeasance or yield-maintenance prepayment penalty throughout the lock-out period
• Assumable — when you sell, the buyer can typically assume the loan with lender approval (assumption fee usually ~1% of loan balance)
• Single-asset or portfolio structures both available
• Pricing: spread over 10-year Treasury + servicing spread, with final pricing typically set 3-5 business days before closing

Where CMBS wins:

• High-leverage net lease (LTV up to ~75%)
• Long-term fixed-rate financing (10 years)
• Stabilized, investment-grade tenant with long remaining lease term
• Buyer who doesn't need to sell or refinance before maturity
• Deal size $2M-$100M+ (smallest loans may cost too much in CMBS fixed expenses to pencil)

2. Life Insurance Companies

Life cos fund commercial mortgages from the asset side of their balance sheet to match against long-duration liabilities (life insurance policies). Major life-co lenders include MetLife, Prudential (now PGIM), New York Life, MassMutual, Pacific Life, Allianz, Northwestern Mutual, and Guardian.

Key features:

• Non-recourse (standard) — same structure as CMBS
• Fixed rate for terms typically 7-15 years, sometimes longer
• Conservative LTV — typically 55-65% for investment-grade net lease, lower for more complex properties
• Yield maintenance prepayment standard (vs CMBS defeasance)
• Relationship-oriented — life cos prefer to lend on properties they understand with borrowers they know
• Typically not assumable — sale triggers payoff (sometimes with negotiation)
• Pricing: spread over Treasury, generally the tightest pricing among all four sources for top-quality deals

Where life cos win:

• Stabilized investment-grade net lease at 50-65% LTV
• Longer-term holds (matches their duration needs)
• Higher-quality credit (life cos are most selective on tenant credit)
• Deal size $3M-$75M+ (some life cos prefer $5M minimum)
• Borrowers who don't need maximum leverage and prioritize pricing

3. Debt Funds

Debt funds are private investment vehicles (often REIT-structured) that originate loans directly and hold them on balance sheet. Examples include Blackstone Mortgage Trust, Starwood Property Trust, Apollo Commercial Real Estate Finance, KKR Real Estate Finance Trust, TPG RE Finance, and many others.

Key features:

• Non-recourse or partial recourse — varies by fund and deal
• Floating rate more common than fixed (many debt funds prefer floating to match their own floating-rate financing)
• Higher leverage available — 70-80%+ LTV for the right deal
• Flexible structures — bridge loans, mezz, preferred equity, stretch senior
• Faster execution — debt funds can close in 30-45 days vs 60-90 for CMBS/life co
• Pricing: meaningfully wider than CMBS or life co — the tradeoff for leverage and speed

Where debt funds win:

• Transitional or value-add deals (not fully stabilized)
• Higher-leverage requirements (>65% LTV)
• Short-to-medium hold periods (3-5 years)
• Deals that CMBS and life cos pass on (tenant issues, short remaining lease term, refinance with cash-out)
• Borrowers prioritizing execution speed and flexibility

4. Banks

Banks (FDIC-insured commercial banks — national, regional, or local) lend on net lease properties typically through their commercial real estate groups. Large bank lenders include Wells Fargo, Bank of America, JPMorgan Chase, and regional banks like PNC, Truist, Regions, and KeyBank.

Key features:

• Typically recourse — banks generally require personal or corporate recourse from the borrower, though non-recourse is available on the strongest deals with appropriate guarantees
• Shorter terms — 5-7 year terms common, sometimes with balloon payments
• Portfolio or balance sheet — banks hold these on their own books, not securitizing
• Relationship-driven — banks prefer to lend to existing commercial customers
• Pricing: varies by bank and borrower; generally between life co and CMBS for stabilized deals
• Flexibility on property type — banks will touch deals life cos and CMBS won't (unusual property types, shorter remaining leases)

Where banks win:

• Smaller deals ($1M-$10M, though some banks go larger)
• Borrowers with existing banking relationships
• Bridge-to-perm or construction-to-perm financing
• Deals requiring faster closing than CMBS
• Situations where recourse from a strong sponsor is acceptable

Side-by-Side Comparison

The Prepayment Penalty Question

One of the biggest structural differences between the four lender types is how they handle prepayment. For a buyer planning to sell before loan maturity, this is often the most important term in the loan.

Defeasance

Used on most CMBS loans. The borrower must "defease" the loan by purchasing U.S. Treasury securities that replicate the remaining cash flows of the loan — the securities are substituted as collateral, and the loan continues to be serviced with the Treasury cash flows rather than the property. The borrower's out-of-pocket cost is the premium required to purchase Treasuries that generate those cash flows, which depends on current Treasury yields vs the loan's original coupon.

When Treasury yields are below the loan coupon, defeasance is expensive. When yields exceed the original coupon, defeasance can even result in a net gain to the borrower.

Defeasance is administratively complex — transactions take 30-60 days to execute and involve specialized defeasance consultants. For net lease buyers planning short holds, CMBS defeasance is often the limiting factor.

Yield Maintenance (YM)

Standard on most life co loans and some CMBS structures. The borrower pays a prepayment fee equal to the present value of the interest the lender would have earned over the remaining loan term, discounted at the current Treasury yield. Mathematically simpler than defeasance (no securities purchase), but conceptually similar in cost when rates have moved lower than the loan coupon.

YM is usually cheaper to execute (no Treasury purchase costs, no specialized consultants required) but produces similar or sometimes higher economic cost than defeasance at equivalent rate environments.

Open / Stepdown

Used on bank loans, debt fund loans, and some structures. Typically a fixed prepayment fee schedule (e.g., 5% in year 1, 3% in year 2, 1% in year 3, open thereafter) or a single "lockout" period with free prepayment after.

Far more flexible than defeasance or YM, and usually the preferred structure for short-hold investors. The tradeoff: lenders price for the flexibility with higher spread or tighter other terms.

Pricing Basis

Understanding how each lender prices helps you evaluate term sheets apples-to-apples:

• CMBS pricing: spread over the 10-year Treasury, set at closing. The "rate lock" happens 3-5 business days before close. Borrowers bear rate risk from application to rate-lock.
• Life co pricing: spread over the matching-duration Treasury (typically 10-year for 10-year loans, 7-year for 7-year loans). Rate-locked at commitment (earlier than CMBS), so borrowers face less rate risk during diligence.
• Debt fund pricing: typically floating-rate — spread over SOFR. Some debt funds offer fixed-rate options at higher spreads.
• Bank pricing: varies. Fixed-rate portfolio loans priced over matching Treasury; floating-rate loans priced over SOFR (or occasionally prime).

A life co offering "T + 175" for a 10-year fixed isn't directly comparable to a debt fund offering "SOFR + 275" for a floating 5-year. You're buying different structures. Always evaluate on all-in cost over your expected hold period.

Which Lender for What Deal

Simplified decision framework:

Core, investment-grade net lease, long hold: Life co is usually best. Conservative terms, tight pricing, matched duration.

Core, high leverage, long hold: CMBS. Access to 70-75% LTV at competitive spreads for stabilized deals.

Short hold (3-5 years) with plans to sell or refinance: Debt fund with open prepayment, or a bank portfolio loan. CMBS/life co prepayment makes short holds expensive.

Transitional, value-add, short remaining lease term: Debt fund is likely the only option. Bank might step in if the sponsor has relationship value.

Small deal ($1M-$3M): Bank or smaller regional lender. CMBS and large life cos may not want the deal at this size.

Unusual property type or tenant: Depends on what "unusual" means. Bank relationships often matter most here.

What to Ask Before Running a Process

Before taking a deal to market, know the answer to these four questions:

1. What hold period is realistic? 3 years vs 10+ changes which lender makes sense.
2. What recourse tolerance does your sponsor have? If no recourse, rule out many banks.
3. What leverage do you actually need? Don't chase 75% LTV if 60% clears your equity return target — lower leverage unlocks the best-priced lenders.
4. What's your timing constraint? If you need to close in 45 days, debt fund or bank. 90 days, everyone.

Running a process against the right 2-3 lender types produces better outcomes than sending a deal to every lender with a pulse. Lender time is limited; if your deal doesn't fit their box, you waste it.

The Bottom Line

Understanding the structural differences between CMBS, life cos, debt funds, and banks is one of the foundational skills in commercial real estate finance. The "best rate" is almost never the best loan — the best loan matches your deal's leverage needs, hold period, prepayment flexibility, and sponsor tolerance for recourse to the capital source that genuinely wants that profile of business.

The fastest way to become a better net lease broker is to be able to look at any deal and name the 2-3 lender types most likely to quote competitively — and know why.
