In addition to the phenomenon of "foreclosure stuffing" described here extensively before, one of the main reasons for the artificial drop in housing supply has been the ongoing government-subsidized, GSE/FHFA endorsed REO-to-Rent initiative, through which large asset managers have been encouraged to take advantage of government funded, risk-free financing and purchase foreclosed properties in bulk, with the intention of converting them into rental properties. The REO-To-Rent has traditionally been open to the biggest of financial companies, or at least those who don't have the stigma of legacy mortgage origination resulting in billions in litigation reserves, which means mostly hedge funds and PE firms. One of the main players in the space, Och-Ziff, decided to pull out of the landlord business in October of last year because, as Reuters reported, "the returns it is generating from rental income are less than expected and it is looking to take advantage of a recent rebound in home prices in northern California." In other words, selling while the selling is good. Of course, there is another, far more traditional way to offload risk while preserving some of the upside: dump the balance sheet exposure to others while giving them a fraction of the potential upside yield. This is precisely what the big banks were doing during the last housing bubble when massive residential mortgage-backed security portfolios were packaged, spliced, securitized (sometime without the feedback of firms like Paulson pre-shorting the MBS courtesy of firms like Goldman) and sold off to other yield-starved investors. Everyone knows how that ended. So fast forward to today, when this final missing link from the credit and housing bubble is finally here too, following news that mega-PE firm Blackstone is pushing forward with the first ever REO-To-Rental securitization.
