Why is GAAP net margin misleading for REITs?

GAAP accounting requires buildings to be depreciated over an assumed useful life, treating them like consumable manufacturing equipment. In practice, well-maintained real estate often holds or increases in value over time rather than depreciating away. Because depreciation sits above the net income line as a substantial non-cash expense, GAAP net margin systematically understates the economic profitability of a property portfolio. This is not an accounting error, it is a conservative convention, but it is why the industry publishes FFO and AFFO as practical alternatives.

What is funds from operations and why do REIT investors focus on it?

Funds from operations adjusts GAAP net income primarily by adding back real estate depreciation and excluding gains or losses on property sales, producing a measure closer to the cash-generating power of the operating portfolio. Adjusted FFO further normalizes for maintenance capital expenditures and non-recurring items. Together these measures give a much more usable view of REIT profitability than GAAP net margin does, and they form the basis on which the sector is typically analyzed, valued, and ranked by specialists.

What Net Margin Means for Real Estate Companies

Net margin inside real estate is structurally distorted by the way GAAP treats real assets. Property owners book significant depreciation on buildings that, in many cases, hold or grow their economic value over time, which drags reported net income well below the actual cash profitability of the portfolio. As a result, GAAP net margin for REITs and property operators often understates the business, which is why the industry standardized around alternative performance measures.

Why It Matters Less in Real Estate

For real estate, the more meaningful margin framework is funds from operations and adjusted FFO, which add back real estate depreciation to produce a number closer to true cash-generating capacity. It is worth noting that acquisition and disposition gains, fair-value adjustments on investment properties, and impairment charges can move reported GAAP net margin meaningfully from period to period even when underlying portfolio economics are stable.

What to Read Alongside

Pair net margin with Revenue to understand portfolio scale, Gross Margin for a view of property-level economics, and Return on Equity for how efficiently equity capital is being deployed across the portfolio.

How this ranking is built

Companies are ranked by net margin as reported in their most recent annual filing with the SEC. Figures shown are in US dollars (or percent, as noted), rounded to two decimals.

Source: annual 10-K / 20-F filings from companies trading on US exchanges (NYSE, Nasdaq, AMEX).
Fiscal year: whichever annual period the company has most recently filed. Fiscal years don't always align with the calendar year, so the "as of FY" stamp above reflects the most common year across the table.
Filtered out: warrants, preferred shares, and duplicate listings that share a parent company's financials.
Update cadence: refreshed as companies file new annual reports (typically within 60–90 days of fiscal year end).
