Last time, we looked at Realty Income (O) as a case study in how using earnings per share (EPS) to calculate payout ratios for real estate investment trusts (REITs) can produce misleading results.
As noted, some public data providers showed payout ratios for Realty Income well above 100%, which might alarm income-focused investors at first glance.
But as noted, the proper metric is adjusted funds from operations (AFFO), a non-GAAP measure that adjusts net income by adding back non-cash items like depreciation and amortization.
This is critical in real estate, where property assets lose book value on paper despite often appreciating in reality. It also excludes gains or losses from property sales, offering a clearer picture of recurring cash flow.
Realty Income is a flagship REIT, well known for its monthly dividend payments and its membership in the S&P 500 Dividend Aristocrats Index, having increased its dividend for more than 25 consecutive years.
Today’s piece builds on that by taking a closer look at the underlying mechanics that allow Realty Income and other high-quality REITs to grow their distributions over decades without compromising sustainability.
Dividends Must Follow Cash Flow
The chart below illustrates exactly what investors should hope to see from a high-quality REIT: consistent growth in AFFO.
While Realty Income’s dividend shows the familiar stair-step pattern of monthly increases over time, what’s most important is that this growth appears supported by a steadily rising AFFO base.
This relationship is key: dividends don't exist in a vacuum. They're funded by real operating cash flow, and here we can see that AFFO has grown roughly in tandem with distributions, especially since the sharp post-pandemic rebound beginning in 2021.
This alignment is what helps ensure long-term dividend sustainability. Without it, dividend growth would eventually come at the cost of balance sheet health.
Occupancy Rate Is Your Anchor
One of the most reliable indicators of a REIT’s health is its occupancy rate. This metric tells you what percentage of a REIT’s total properties are currently leased and producing rental income.
It’s calculated quarter to quarter as the number of leased properties divided by the total leasable properties in the portfolio.
What’s considered “good” varies depending on the REIT’s focus. For example, post COVID-19 an office REIT may naturally carry a bit more vacancy than one focused on essential retail. But in all cases, stability is key.
Realty Income continues to set the standard. As of March 31, 2025, its occupancy rate stood at 98.5%. That’s down just slightly from 98.7% at the end of 2024 and 98.6% a year prior.
In other words, almost no change, which is especially impressive when managing over 15,000 properties. That level of consistency offers a clear signal that tenant demand remains strong and that management is effectively executing renewals or filling vacancies quickly.
For income-focused investors, this stability is foundational. A high, steady occupancy rate anchors rental revenue, which in turn supports consistent FFO growth.
Over the long run, we believe investors should look for REITs with occupancy rates consistently above 95% and minimal quarter-to-quarter volatility.
Same Store Rental Revenue is Your Organic Growth Driver
While occupancy rate provides a solid foundation, it doesn’t tell the full story. What really drives income growth is how much tenants are paying over time and whether those payments are increasing at a healthy pace. That’s where same store rental revenue comes in.
Same store rental revenue compares the income generated by a consistent set of properties over time, filtering out the noise from acquisitions or dispositions. It reflects the organic growth of the portfolio by assessing whether existing tenants are renewing at higher rents.
Ideally, those increases help outpace inflation over time. If inflation averages 2%, you want to see rental revenue growth comfortably at or above that level to preserve purchasing power.
Realty Income’s latest quarterly results show same store rental revenue rose 1.3% year-over-year across 14,702 properties. While slightly below the inflation benchmark, that still reflects a positive contribution to FFO and ultimately dividends.
In today’s tighter environment for tenants and rent growth, any gain, particularly across such a large base is notable. It suggests leases are being executed or renewed at favorable terms, reinforcing Realty Income’s reputation for operational discipline and tenant quality.
