Lease Durability Index: Measuring Tenant Quality, Renewal Probability, and Rent Resilience
A framework for evaluating whether rental income is repeatable, not just temporarily elevated.

Headline rent growth can be fragile
Strong asking rents do not automatically translate into stable long-term income. Durability depends on tenant affordability, renewal behavior, and competitive supply pressure.
A practical durability scorecard
Track renewal ratios, turnover intervals, and vacancy refill speed by building and micro-location. These signals reveal how income behaves when market momentum cools.
What durability means for valuation
Assets with resilient lease profiles generally support tighter exit spreads and stronger downside protection. Durable income quality is often rewarded at both hold and exit stages.
