How We Partner
A process built for sponsors who need a decisive capital partner.
From first call to closing, Castelan moves at the pace institutional transactions demand — with the structuring flexibility a family-office and closely held platform can offer.
Our Process
Four steps from introduction to close.
Origination & Sourcing
Transactions are sourced directly through sponsor relationships, brokerage networks, and off-market introductions — screened against our target markets and asset criteria before diligence begins.
Underwriting & Diligence
Our team underwrites the market, the asset, and the sponsor's track record in parallel — stress-testing the business plan against conservative rent growth, exit cap rate, and capital expenditure assumptions.
Structuring & Capital
Once terms align, we structure the equity — GP co-investment, programmatic JV, or preferred equity — around the sponsor's promote, control provisions, and refinance or exit timeline.
Asset Management & Reporting
Post-closing, Castelan maintains active oversight — quarterly reporting, budget review, and capital markets support through refinance or disposition.
Partnership Models
Structured around how the sponsor wants to grow.
01
GP Co-Investment
Equity committed alongside the sponsor's own capital on a single transaction — aligning incentives from acquisition through disposition, with shared control provisions.
02
Programmatic Joint Venture
A standing capital commitment to sponsors with a repeatable pipeline — reducing time-to-close on future transactions and building a long-term platform relationship.
03
Preferred & Structured Equity
Downside-protected capital for sponsors who want to preserve upside and control — priced to the risk of the specific business plan rather than a fixed template.
“We underwrite the sponsor as closely as the asset. Alignment on the business plan — not just the return — is what makes a partnership work through a full hold period.”
