Shelter Growth Capital Partners

Shelter Growth Capital Partners has raised more than $200 million since January, according to a person with knowledge of the matter, bringing its assets under management to $482 million as of July 1. That's a big increase for the fund, which was started in early 2015 with $11 million. Shelter Growth buys mortgage loans, using leverage, or borrowed money, that can amplify investments. Including leverage, the firm at the start of June managed about $1.1 billion, more than double its assets, according to a regulatory filing. The firm is betting on the $13.5 trillion residential and commercial mortgage markets, which banks have pulled out of following post-crisis regulatory burdens.
