REIT lease expiration concentration measures how much of a portfolio's contractual rent or leased area is scheduled to expire during specified future periods.
Common weighting bases include:
- annualized base rent;
- rentable square feet;
- gross leasable area; and
- lease count.
Why the maturity ladder matters
A portfolio with unusually heavy expirations in one year can face concentrated:
- renewal risk;
- vacancy risk;
- tenant-improvement spending;
- leasing commissions; and
- mark-to-market exposure.
A smooth lease maturity ladder can reduce timing concentration, although it does not eliminate tenant or market risk.
Filing examples
Realty Income discloses lease expirations by annualized base rent. Rexford Industrial discloses scheduled expirations by rentable square feet.

Lease expiration concentration measures timing exposure, not the probability that tenants will leave.
Part of the REIT Leasing and Capital Deployment
Connect lease duration, occupancy states, rent mark-to-market, tenant quality and concentration, development returns, and acquisition or disposition pricing to understand commercial real estate cash-flow durability and external growth.
How the model fits together
- Lease rollover and rent mark-to-market: Weighted average lease term and lease-expiration concentration frame when rent rolls, while tenant retention, cash leasing spreads, GAAP or net-effective leasing spreads, and net-effective rent per square foot show how much space renews and at what economics.
- Occupancy, tenant quality, and contractual rent base: Annualized base rent provides the contractual rent weighting base, leased and economic occupancy separate signed space from rent-paying space, and investment-grade mix, top-tenant concentration, and contractual rent growth describe the credit, concentration, and embedded growth profile of that rent stream.
- Development and asset recycling: Development pipeline shows future capital commitments, development yield relates expected stabilized NOI to development cost, and acquisition and disposition cap rates frame the going-in yield bought versus the property yield sold. Issuer definitions differ, so these measures support capital-allocation analysis rather than a standardized arbitrage formula.
