funds from operations

Funds from operations restates reported earnings by adding back real estate depreciation and adjusting for gains on property sales, because depreciating buildings that hold their value distorts earnings comparisons. In the cataloged sources FFO appears three ways at once.

Nareit’s T-Tracker lists FFO first among its seven headline metrics — “FFO, NOI, same-store NOI, dividends, occupancy, leverage and cap rates” — broken out by property sector, with the lodging/resorts, residential and office sector hubs each publishing the same quarterly aggregates. SEC EDGAR treats ffo as a filing-search keyword for lodging REITs, and the SEC XBRL Company Facts API carries ffo-modeling and leverage-metrics tags on its per-filer fact feed. REITNotes exposes per-period FFO amounts through its REITFFO tool across an 839-REIT database (Q2 2026) after a free signup.

Reported net income alone misprices REITs, and any dataset that stops at reported earnings inherits the depreciation distortion straight into your models.

• Comparability depends on a common definition. Nareit computes T-Tracker aggregates on one basis across industrial, lodging, residential and office portfolios; mixing a vendor’s bespoke FFO with the Nareit baseline manufactures growth that is not there.
• Filings carry the raw material. Searching EDGAR on the ffo keyword surfaces the filings, and the XBRL company-facts feed gives per-filer facts you can rebuild the measure from.
• Some series sit behind signup walls. REITNotes releases FFO amounts only after free registration across its 839-REIT universe — build that step into the collection job.

Sector context lives on the hotel-resort-reits data and industrial-reits data hub pages.

1. Confirm quarterly sector breakouts. Nareit’s T-Tracker reports FFO by property sector, not just portfolio-wide totals; a source without the sector cut limits peer comparison.

1. Check the metric family around it. FFO sitting beside NOI, same-store NOI, occupancy, leverage and cap rates lets you normalize per sector.

1. Test filer-level reconstruction. Pull the SEC XBRL Company Facts API and confirm the ffo-modeling and leverage-metrics tags resolve for the filers you track.

1. Verify benchmark linkage. Monthly and annual XLS files from the FTSE Nareit US Real Estate Index Series — tagged index-returns, total-return and benchmark — sit alongside the FFO series on reit.com, tying fundamentals to returns.

1. Price the access friction. REITNotes’ REITFFO tool requires a free signup before quarterly FFO rows are exposed.
