If you saw my recent story ("Deep pocketed investor paying cash for hundreds of Twin Cities homes") about Invitation Homes, a division of Blackstone, buying once-distressed houses in the Twin Cities as part of a massive rental portfolio - and a hedge on the housing recovery, you'll be interested in a recent story that says the Oaktree Capital Group is preparing to put its portfolio of 500-plus, fully leased rental homes on the market, suggesting that the group is ready to exit the buy-to-rent business. Oaktree doesn't have any holdings in the Twin Cities, but this move might be a sign of things to come for other investors.
