REIT investment-grade rent mix measures the portion of portfolio rent associated with tenants, parent companies, guarantors, or other counterparties that meet an issuer's investment-grade definition.
A common analytical form is:
Investment-Grade Rent Mix =
Rent from Investment-Grade Counterparties ÷ Total Portfolio Rent
Why it matters
The measure can help frame tenant credit quality and the durability of contractual rent.
But it does not eliminate property-level risk, lease rollover risk, or the possibility of credit deterioration.
Methodology differences
Check whether the REIT:
- uses tenant or parent ratings;
- includes affiliates;
- accepts NAIC ratings;
- uses published ratings only; and
- weights by ABR, revenue, or another measure.
Realty Income and Agree Realty both disclose investment-grade exposure as a share of annualized base rent, but their definitions should still be reviewed before direct comparison.

Investment-grade rent mix is a tenant-credit composition measure, not a guarantee of rent collection.
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.
