Estimating REIT NAV from NOI, Cap Rates, and Claims
Distinguish the U.S. REIT distribution test from FFO, then use an illustrative NOI, cap-rate, and debt calculation to assess the assumptions behind NAV per share.

1. Structural Mandates and Corporate Tax Conduit Rules
In the United States, a Real Estate Investment Trust (REIT) is an institutional vehicle designed to aggregate investor capital for purchasing, operating, and financing income-producing commercial properties. Under U.S. tax law, a REIT generally must distribute at least 90 percent of its taxable income to shareholders to qualify for the regime; rules and tax treatment differ by jurisdiction. REIT returns are not equivalent to direct property ownership.
2. Accounting Earnings and FFO
Real-estate depreciation lowers accounting income but does not by itself measure a building’s economic value or maintenance needs. Nareit’s U.S. FFO definition adjusts net income for specified items, including gains on property sales, and adds back real-estate depreciation and amortization; FFO is a non-GAAP measure. It is not the same as operating cash flow or cash available for distribution, so it should be read alongside capital spending, debt service, and measures such as AFFO.
3. Estimating NAV and Comparing It with Market Price
A publicly traded REIT’s market price can differ from estimates of the underlying property value. One simplified direct-capitalization method divides stabilized net operating income (NOI) by an appropriate capitalization rate, then adds other assets and subtracts debt and senior claims to estimate NAV. NOI and cap rates are estimates, and results depend on valuation date, asset mix, liabilities, and transaction costs. A NAV discount or premium alone does not establish mispricing or a buy signal.
Illustrative calculation: If stabilized annual NOI is assumed to be $50 million and the assumed cap rate is 5%, estimated property value is $50m ÷ 0.05 = $1,000m. Simplifying to no other net assets, subtract $400m of debt and $100m of preferred or other senior claims: estimated common equity NAV is $500m. With 50m common shares, estimated NAV is $10 per share; a $8 share price is 0.8× this estimate. This is arithmetic under stated assumptions, before other assets/liabilities, dilution, transaction costs, or uncertainty in NOI and cap rate; a discount alone does not show undervaluation.
