CFDL

This example models a development lifecycle with construction-phase financing (interest-only) and permanent financing (debt service). The transition is hardcoded by stream dates: no events are used.

  • Construction interest: loan.construction — stream runs from 2026-01 to 2027-06 (18 months).
  • Permanent debt service: loan.permanent — stream runs from 2027-07 to 2031-12 (after conversion).

Property-side: CRE pack for construction stub, lease, and exit; standalone streams for ops revenue and ops expense (per guidance). Loan-side: standalone streams for construction interest and permanent debt service.
