The last time a big financial firm rushed into buying rental exposure (just as others were quietly leaving the sector in droves and when the ingenious Wall Street was coming up with such derivatives as Rent-Backed Securities to dump their exposure to dumb yield-starved Germans and Asians), it had a very unhappy ending for the buyer. That transaction of course was Lehman Brothers' rushed acquisition of landlord Archstone, which as many have noted over the years, was a big contributor to the Lehman bankruptcy once the rental payments dried up. But then again, as others have pointed out, Lehman was so deep in its real estate exposure by then it really had no choice but to keep doubling down all the way to the bitter end. Which may explain why while most other brand name hedge funds and P/E firms are now cashing out of the US housing market whose second bubble may already have peaked (only last night Goldman said that "On house prices, we have started to see the first signs of deceleration and expect a slowdown"), Blackstone, which is now the US' largest landlord, is digging in its heels and is not letting go. In fact, it is adding to its exposure - as the WSJ reported overnight, Blackstone has invested another $1 billion to purchase GE's stake in 80 apartment complexes amounting to 30,000 apartment units, located in Dallas, Atlanta and other parts of Texas and the Southeast.
