I know, I know, I'm a little behind, but late is better than never.
The trophy DC office property located on the 700 and 800 blocks of Pennsylvania Avenue was part of the Beacon Seattle Portfolio in WBCMT 2007-C31, WBCMT 2007-C32, BSCMS 2007-PW16, BACM 2007-2, MSC 2007-IQ14, and MSC 2007-HQ12. The $905 psf price implies an approximate cap rate of 4.22%.
Note that the $2.644b loan (20 properties) was extended from a May 2012 maturity to a 2017 maturity, and this should result in a partial and substantial release from the loan.
I'd definitely keep an eye out on any current- or next-pay bonds on these deals. For example, it represents 15.66% of the collateral behind the WBCMT 2007-C31 A2 that is currently offered at 255 $104-11 - all else equal, if you assume the full sales price is released, you lose nearly 100 bps of yield and your bond shortens by over 1 year. And, as Barclays pointed out earlier this week, or maybe last week, the reserve requirements are likely to go down as well resulting in further releases.
