Question 1

Why are San Francisco CMBS special servicing transfers so large compared to other markets?

Accepted Answer

San Francisco's CMBS origination market in 2015-2019 was dominated by large downtown office buildings at peak-cycle valuations. Single loans of 100-500 million dollars were common for major Financial District or South of Market office assets. When those buildings lost 40-60% of their 2019 values, the resulting CMBS losses were outsized relative to the loan count. The concentration of large loans in a single asset class (office) in a single geography (downtown SF) has made San Francisco one of the highest-profile CMBS special servicing markets in 2024-2026.

Question 2

What is the timeline for a San Francisco CMBS special servicing workout?

Accepted Answer

San Francisco CMBS workouts are taking longer than in most markets due to the scale of losses, the complexity of capital stacks (multiple mezzanine layers on many downtown office loans), and the difficulty of establishing a clearing price in a market with limited comparable sales. From transfer to resolution, SF office CMBS workouts have been running 18-30 months in recent cycles. The California trustee sale option is available but rarely used on large downtown SF assets given the title and junior debt complexity.

Question 3

Are San Francisco CMBS office-to-residential conversions viable for special servicing buyers?

Accepted Answer

San Francisco office-to-residential conversion is legally viable (the city has streamlined approval processes for qualifying conversions under state housing law) but technically challenging. Older Financial District office buildings with large floor plates are harder to convert than smaller 1960s-1970s mid-rise office buildings with narrower floor plates and window-to-core ratios that support residential units. Buyers targeting SF CMBS office for conversion should commission a conversion feasibility study as part of their due diligence, and should engage a San Francisco land use attorney to assess permitting timelines before making an offer.
