What a 7% yield actually needs to survive

Contracted is not the same as secure

A nine-year lease from a tenant with a two-year cash runway is a two-year lease with paperwork.

Escalation versus inflation

15% every three years is roughly 4.8% annualised. Check that against your inflation assumption before calling it growth.

Exit assumptions

If your entry and exit cap rate are the same, say so explicitly. If your exit assumes compression, that is a bet, not a base case.
