Also in 10 years a home will be worth more than you pay at today's prices. i would think blackrock has area's of the country its targeting. if you pick the right markets this is a genus move even if the homes go down 10% more in the long run this will be a money making machine. its sad though it shows how people won't have the money to buy in the future because 1/3 of american's make less than 25k a year.
