Direct Answer
This page is a research brief for a REIT Due-Diligence Note on Realty Income Corporation (O). It is not yet a completed analysis: no figures below have been pulled from a primary source, and none are stated.
See “What This Note Is Teaching” below for the specific research skill this brief demonstrates, and “Primary Sources to Review” for exactly what the completed note will draw from.
What This Note Is Teaching
How to evaluate a net-lease REIT: property and tenant concentration, lease structure, and funds from operations (FFO) rather than net income, the metric REIT investors typically rely on instead.
REIT Snapshot
Realty Income Corporation is a real estate investment trust that owns and leases commercial properties, predominantly under long-term net-lease agreements with retail, industrial, and other commercial tenants. It trades on the NYSE under O and is publicly known for paying dividends on a monthly rather than quarterly schedule.

Primary Sources to Review
The finished note will be built from these primary documents, not from a secondary summary or another publisher's report:
- Most recent Form 10-K and Form 10-Q, including the FFO reconciliation typically provided in the earnings release
- Most recent quarterly earnings press release and supplemental operating and financial data package
- Most recent investor presentation for tenant and industry concentration detail
- Dividend declaration history for the monthly payment record

Risks & Contrary Evidence
General risk categories relevant to this business, to be substantiated with specific, sourced evidence once the completed note is written:
- Tenant concentration and tenant-credit risk under long-term leases
- Interest-rate sensitivity given the REIT structure’s reliance on external financing for growth
- Industry concentration risk if a large share of tenants operate in the same sector
- Occupancy and re-leasing risk at lease expiration
Open Questions
- What is the current tenant and industry concentration among the top lease-revenue contributors?
- What is funds from operations (FFO) per share, and how does the dividend payout ratio look measured against FFO rather than net income?
- What is the portfolio’s current occupancy rate and weighted-average remaining lease term?
What New Information Would Change This Analysis
- A disclosed tenant bankruptcy or lease default materially affecting a top tenant
- An FFO payout ratio, once pulled from the primary filing, materially different from the pattern this note assumes
- A material acquisition or portfolio disposition announced after this brief was written
Source List With Dates

Frequently Asked Questions
What is a REIT Due-Diligence Note?
Property portfolio, lease structure, and funds-from-operations mechanics of a real estate investment trust.
Why isn’t the Realty Income Corporation note finished yet?
This page is a research brief: an outline of what the finished note will cover and exactly which primary sources will support it, published before the data pull rather than after. Swoopr’s live data integrations do not include an archived source for the figures this note needs, and the site’s editorial policy does not allow publishing a number that has not been pulled from a named primary source. See the Primary Sources to Review section on this page for the specific documents the completed note will draw from.
Where does Swoopr source the data for research notes?
Swoopr’s research notes are built from primary filings and disclosures, such as SEC filings, a fund’s own prospectus, or an issuer’s own investor relations materials, never from competitor stock reports or secondary summaries. See the References section on this page for where to start, and the Research Methodology page for the full research process this note follows.
Why does a property trust note start from funds from operations rather than net income?
Because real estate depreciation is a large non-cash charge that reduces reported earnings without reflecting the economics of buildings that are being maintained. Funds from operations adds it back and removes gains and losses on property sales, producing a measure closer to the recurring cash the portfolio generates. Net income for a property trust can be a small fraction of its cash generation, which makes an earnings-based multiple close to meaningless.
What is the quarterly supplemental package, and why is it a primary source here?
A detailed disclosure most listed property trusts publish alongside results, containing property-level and portfolio-level information that the regulated filings do not present in that form: occupancy, lease expiry schedules, same-store performance, tenant concentration, and the debt maturity profile. It is produced by the trust itself, which makes it primary, and it is where most of the operating detail a due-diligence note needs actually lives.
What does a lease expiry schedule reveal that occupancy does not?
When the current occupancy has to be re-established. A portfolio fully leased today with a large share expiring within a short window faces a leasing market on a date fixed years earlier, while one with expiries spread evenly renegotiates a small share at a time. Occupancy is a snapshot; the expiry schedule is the forward exposure, and two trusts with identical occupancy can be positioned very differently on it.
Why is tenant concentration examined separately from property diversification?
Because a portfolio can be geographically spread across many buildings while depending on a small number of tenants across all of them. The relevant exposure is to the credit of whoever pays the rent, not to the location of the property. A trust with hundreds of properties and a concentrated tenant roster carries a credit exposure that a property count conceals entirely.
How does the payout requirement shape a property trust’s balance sheet?
By removing retained earnings as a funding source. A trust distributing most of its taxable income cannot fund acquisitions or development from retained cash, so growth depends on issuing equity or raising debt. That makes the cost of capital a direct constraint on growth, and it means the share price itself affects whether expansion is accretive, which is a feedback loop ordinary operating companies do not face in the same way.
What does a monthly rather than quarterly distribution schedule change analytically?
Very little about sustainability, and something about the commitment. The coverage question is the same: whether recurring cash generation supports the total annual distribution. What a monthly schedule does is make any change highly visible and frequent, which raises the cost of adjusting it and can make a trust more reluctant to reduce a distribution that the cash flow no longer comfortably supports.
