The manager is reportedly looking to shift loans from multiple vintages across its Private Markets Credit Strategies and Multi-Asset Credit funds.
The £165 million deal was completed through a joint venture, with Partners Group investing from its real estate secondaries strategy.
The firm has reportedly engaged with prospective buyers to facilitate liquidity for investors in a US-based open-ended fund managed by Blackstone Property Partners.
The deal will support the UK housebuilder's expansion toward 7,000 homes a year, with Apollo retaining control.
The partnership will also develop products for wealth investors, beginning with an evergreen private equity secondaries fund expected in the coming weeks.
The Jefferies-advised deal extends the firm's ownership over a portfolio of properties from its 2015-vintage White Rock Fund II platform.
