Bridge Loan vs CMBS: Which Structure Fits Your Deal?

The Core Difference: Transition vs Stabilization

Bridge and CMBS are both commercial real estate loans, but they solve fundamentally different problems. Bridge is transitional capital — financing that covers a specific change in the property's life: acquisition speed, value-add renovation, lease-up from C of O to stabilization, PIP execution, or CMBS maturity rescue. CMBS is stabilization capital — long-term, fixed-rate, non-recourse permanent debt for properties that are already stabilized and will be stabilized for the foreseeable future.

The mistake first-time sponsors make is thinking of them as competitors — choosing one instead of the other. Experienced sponsors think of them as sequential: bridge for the transition period, then CMBS refinance at stabilization. The bridge premium over CMBS (200–500+ bps of rate) is the price of transition flexibility, NOT an inferior product.

The second mistake sponsors make is using bridge when CMBS works today. If a property is stabilized, the tenant base is sticky, the DSCR supports 1.25x+, and CMBS is pricing at 6.5%–7.5%, paying 9%–10% for bridge is paying 250+ bps for capital flexibility you don't need. Save the bridge premium for deals that actually need transition capital.

The third mistake is using CMBS when the property isn't ready. CMBS underwriters require 85%+ occupancy for 12+ months trailing. If you're closing on a property with 65% occupancy that needs 18 months of lease-up, CMBS will either decline or underwrite at such a low LTV that the sponsor equity check doubles. Bridge is the right structure for that deal, with a pre-mapped CMBS refinance at stabilization.

Head-to-Head: Rate, Terms, Structure

**Rate.** Bridge 7.5%–13% depending on asset class and sponsor. CMBS 6.0%–10% depending on property type and LTV. CMBS is materially cheaper per year on rate — always. The question is whether CMBS is available for your specific deal today.

**Amortization.** Bridge is 100% interest-only (no amortization). CMBS is typically 30-year amortizing on multifamily/retail/industrial/self-storage and 25-year on office/hotel. Some CMBS offers 2–5 years of interest-only during the term with amortization kicking in later.

**Term.** Bridge 6–36 months (with 6-month extensions typical). CMBS 10-year fixed standard (5-year and 7-year variants available). Bridge is designed for short-term transitional use; CMBS is designed for long-term hold.

**LTV / LTC.** Bridge typically 65%–75% LTV on purchase, 75%–80% LTC on value-add (acquisition + capex). CMBS 75% LTV on stabilized multifamily / industrial / grocery retail; 65%–70% on unanchored retail / hotel; 55%–65% on office. Roughly similar LTV limits.

**DSCR.** Bridge typically 1.0x–1.15x on pro-forma (allows for current stress during transition). CMBS 1.25x–1.60x on trailing 12-month NOI (stricter — underwrites to current-state cash flow).

**Close time.** Bridge 14–45 days depending on asset class. CMBS 45–75 days from LOI signature. Bridge is materially faster — which matters when acquiring off-market deals on compressed timelines.

**Recourse.** Bridge varies by deal and sponsor — institutional bridge often non-recourse with bad-boy carve-outs; smaller bridge deals or construction-adjacent bridge often include completion guarantees or partial recourse. CMBS is uniformly non-recourse with standard bad-boy carve-outs (fraud, voluntary bankruptcy, waste, misappropriation).

**Prepayment.** Bridge typically allows prepayment with 1–3 months of interest as the only fee (or fully open after 12 months). CMBS has defeasance or yield maintenance — both can be expensive when interest rates drop between origination and prepayment.

**Covenant tests.** Bridge typically includes ongoing covenants on construction progress, lease-up milestones, DSCR stress tests during transition. CMBS has annual financial reporting but few active covenants — primarily bad-boy carve-outs and property-level insurance / tax compliance.

When Bridge Beats CMBS

**Transitional cash flow.** Property not yet stabilized — value-add with 18–30 months of lease-up, C of O + lease-up, PIP renovation + stabilization. CMBS will decline or size way down. Bridge is the right structure; CMBS refinance comes at stabilization.

**Fast close required.** Off-market deal closing in 14–21 days. CMBS can't close that fast — 45–75 day minimum. Bridge closes 14–45 days depending on asset class. Premium pricing is the cost of speed.

**Short hold horizon (3–5 years).** If you're planning to sell in 3–5 years, CMBS defeasance cost at exit can eat the rate savings. Bridge-to-bank-debt or bridge-then-sale often beats CMBS on total 5-year IRR.

**CMBS maturity rescue with weak trailing NOI.** Existing CMBS matures in 6 months; NOI is 20%+ below what new CMBS would require. Bridge gives 18–30 months to improve NOI, then CMBS refinance at stabilization.

**Partnership restructure / GP buyout.** Bridge funds the partner buyout; permanent CMBS refinances at stabilization post-restructure.

**1031 exchange bridge.** Bridge closes inside the 180-day 1031 window (standard CMBS can't), then CMBS refinances 12–24 months post-exchange.

When CMBS Beats Bridge

**Stabilized property, 7+ year hold horizon.** Property is at 90%+ occupancy for 12+ months; trailing DSCR supports 1.25x+; you're planning to hold 7+ years. CMBS wins on rate (6.5%–7.5% vs 9%–10%), amortization (builds equity), and 10-year rate certainty. Save bridge premium for deals that actually need transition capital.

**Rate certainty matters.** In a rising-rate environment, locking in 10-year fixed at today's CMBS rates is material value. Bridge exposes you to re-financing into a higher-rate CMBS environment at stabilization.

**Non-recourse is critical.** CMBS is always non-recourse (with carve-outs). Bridge sometimes is, sometimes isn't. For sponsors with significant personal net worth exposure, the non-recourse certainty of CMBS is a major factor.

**Large loan size $25M+.** Very large CMBS SASB (Single-Asset Single-Borrower) deals access institutional CMBS conduits at tight spreads; equivalent bridge pricing at that scale is typically 200+ bps wider.

**Multifamily with agency alternative.** For stabilized multifamily, Fannie Mae DUS or Freddie Mac Optigo are typically tighter than CMBS (25–75 bps) — take agency, not CMBS, and not bridge.

The Bridge-to-CMBS Decision Matrix

For value-add, lease-up, and CMBS-maturity-rescue deals, the real question isn't 'bridge or CMBS?' — it's 'direct-to-CMBS at closing, or bridge now with CMBS refinance at stabilization?' Run a 5-year IRR model on both scenarios:

**Scenario A: Direct-to-CMBS at closing.** Take CMBS at today's rate with whatever LTV the trailing NOI supports. Accept potentially lower LTV than sponsor wanted. Accept defeasance risk if planning to sell or refinance before maturity.

**Scenario B: Bridge-to-CMBS.** Take bridge at today's rate for 24–30 months. Execute value-add / lease-up / PIP during bridge term. Refinance into CMBS at stabilization, at a higher LTV (once trailing NOI supports) and possibly a better rate (if rates have moved down).

The bridge-to-CMBS scenario wins when: (a) stabilization unlocks 10–20% higher LTV than direct-CMBS would support, (b) the sponsor can pull out more equity at stabilization refinance, (c) the rate environment is neutral or improving, (d) the value-add thesis is credible and on a realistic timeline.

Direct-to-CMBS wins when: (a) property is already stabilized or close to stabilized, (b) rates are rising and locking in today protects future cost of capital, (c) the value-add thesis is marginal and bridge premium won't be recovered at stabilization refinance.
