One can not blame Mort Zuckerman for being bullish on housing (or at least some segments thereof): after all the outspoken Obama critic just splurged $930 million on the John Hancock building (which recently went into foreclosure at a $660 million valuation, but Mort has a story about how improvements in the parking lot and somesuch are worth the 50% hike in price). Yet what the Boston Properties chairman likes in commercial real estate (and for a contrarian and somewhat more lucid view feel free to peruse comparable thoughts by Howard Davidowitz) he loathes in residential real estate, which would be bad news for Bank of America if the bank's real name wasn't Bank of Banana Republic. In an interview with CNBC's finest, the USNews editor said that the record shadow inventory is "what’s going to put downward pressure on residential prices. And in my judgment, that’s going to continue forat’s going to continue for several years. We’ve seen home prices go down now for four months in a row, according to the Case-Shiller Index , by 1.3 percent in the last month. So it’s an accelerating downtrend in those prices. This is on top of three to four years of declines.” Oddly enough, no mention of the fact previously discussed by Davidowitz that "we have 21 square feet of selling space for every man woman and child in this country" but then again that may not be too bullish for CRE. And at the end of the day everyone has an agenda.
