Add mezz when leverage need is incremental, the deal supports the additional debt service, and the sponsor wants to keep the equity stack thin. Bring JV equity when leverage is already at senior-lender ceilings, the deal is heavier business plan, or the sponsor needs balance-sheet capacity for other deals.
How sponsors decide between filling the gap with debt or equity
Cash-flow test: mezz adds debt service. On a stabilized deal with strong DSCR coverage, the deal can absorb mezz comfortably. On a value-add or lease-up deal where DSCR is thin or projected, the additional mezz debt service can push the deal into cash trap or a covenant breach. JV equity has no scheduled debt service, distributions only happen when there is excess cash flow.
Sponsor balance-sheet test: every dollar of LP equity raised reduces the sponsor's reliance on its own balance sheet and frees capacity for other deals. Sponsors running multiple concurrent deals often prefer JV equity (deal-specific) over mezz (debt obligation tied to one property) because the equity model preserves balance-sheet flexibility.
