New York City—Though CMBS delinquencies declined for the sixth quarter in a row in Q2, multifamily loans are exhibiting some weakness. According to Standard & Poor's structured finance division, in the second quarter, delinquent CMBS in terms of loan amount fell 5% over the first quarter to $2.35 billion. The Q2 figure is also 40% off its peak of nearly $4 billion, achieved in December 2003. When measuring the rate of delinquencies, that figure fell three basis points from Q1 to .55%, or 71% of its peak of nearly 2% at year-end 2003. The larger rate drop, says the locally based firm, reflects the significant growth of the CMBS market.

Specifically, multifamily CMBS delinquency rates declined by six basis points to 1.05%. Still, S&P notes that apartments account for the bulk of the delinquencies, mainly attributable to the decline of the condominium sector. "With excessive condo supply and speculative buyers exiting certain markets, developers are realizing that condo conversions may not currently be the best execution," S&P analysts say. "They are reevaluating their business strategies to determine if it is more feasible to abandon a conversion plan and return units to rental status."

This move, the firm warns, could lead to additional refinance risk for the impacted loans.S&P indicates that it is closely monitoring several condo conversion deals with heightened stress levels—Credit Suisse First Boston Mortgage Securities series 2005-CND1 and CND2, and Lehman Brothers Floating Rate Commercial Mortgage Trust 2006-CCL2. The firm has expressed concern that in some markets, most notably Florida, scheduled conversion plans may not take place or may be delayed due to market conditions. In some cases, particularly areas with rising apartment rents, developers are opting to convert back to rentals, or not convert at all.
