Ways to partner with Greenline

Explore our partnership and investment structures.

Co-GP

We contribute local market knowledge, established relationships, and specialized construction expertise. We partner with Co-GPs who can provide additional capital, financial strength, or access to investor networks. Co-GPs participate as active partners and receive a share of the General Partner’s profits in exchange for their contribution.

Preferred Equity

Preferred equity investors rank senior to common equity but remain subordinate to the senior lender. In exchange for their senior position and defined return profile, their upside is generally capped. Preferred equity typically targets returns of 8–14%, depending on the project, risk profile, and investment structure.

LP Common Equity

Most of our investors participate as Limited Partners (LPs). LPs are passive investors with no day-to-day management responsibilities. Their liability is generally limited to the amount of their investment, while their potential returns are uncapped, allowing them to participate fully in the project's equity upside.

For the cabinets at 186 Huron, weathered wood from the pre-existing building was polished and repurposed. This recycling saved on cost and lowered the carbon footprint of the build-out. Plus, the vintage appearance was a draw for buyers.
