Case Study: CMBS Loan Execution on a $15M Office Building

8 min
5/6

Key Takeaways

  • CMBS offers higher leverage (70% LTV) and non-recourse terms but with rigid structures.
  • Life insurance companies offer the lowest rates but the most conservative leverage.
  • Portfolio loans offer prepayment flexibility and recourse but shorter terms and higher rates.
  • Financing selection must align with hold period—CMBS rigidity is costly for short holds.

This case study examines the process of obtaining a CMBS loan on a stabilized office property, illustrating the underwriting, structuring, and execution differences between CMBS and conventional commercial lending.

Scenario: Stabilized Suburban Office — $15M Acquisition

Scenario: Stabilized Suburban Office — $15M Acquisition

An investor group is acquiring a 60,000 SF Class A suburban office building for $15 million. The property is 92% occupied with a weighted average lease term (WALT) of 5.2 years and generates $1.35 million in NOI. The investor solicits financing from three sources: a regional bank offering a portfolio loan, a national bank offering a CMBS execution, and a life insurance company. The target is maximum non-recourse leverage at the lowest all-in cost.

Analysis and Execution

Analysis and Execution

The investor selects the CMBS execution for three reasons: (1) highest loan amount ($10.5M vs. $9.75M and $9.0M), reducing required equity by $1.5M; (2) non-recourse structure protecting personal assets; and (3) 10-year fixed rate providing certainty through the hold period. The trade-offs are the longer closing timeline (75 days), rigid prepayment structure (defeasance would cost approximately $800K at current rates), and limited modification flexibility. The investor proceeds with CMBS, understanding that early exit or refinance will be expensive, aligning with their planned 10-year hold strategy.

Key Takeaways

  • CMBS offers higher leverage (70% LTV) and non-recourse terms but with rigid structures.
  • Life insurance companies offer the lowest rates but the most conservative leverage.
  • Portfolio loans offer prepayment flexibility and recourse but shorter terms and higher rates.
  • Financing selection must align with hold period—CMBS rigidity is costly for short holds.

Common Mistakes to Avoid

Choosing a CMBS loan for a property you plan to sell or refinance within 5 years

Consequence: Defeasance or yield maintenance costs can add 15-30% of the loan balance to the exit cost, significantly reducing returns

Correction: Model the prepayment penalty at your expected exit date and compare the total cost against a portfolio loan with more flexible prepayment terms

Ignoring the impact of rising rates on CMBS debt yield requirements at refinance

Consequence: A loan that qualifies at origination may not qualify at refinance if rates rise and debt yield thresholds tighten

Correction: Stress-test the refinance scenario at origination: model 100-200 bps higher rates and verify the property still qualifies on debt yield and DSCR
