REITs, FFO and AFFO

Real estate investment trusts require a different analytical language. Standard EPS and FCF are distorted by depreciation on assets that often hold or increase in value. REIT analysis depends on FFO, AFFO, occupancy, lease quality, leverage, and the spread between acquisition yields and funding costs.

Structure

What is a REIT?

A Real Estate Investment Trust (REIT) is a company that owns, operates, or finances income-producing real estate. In exchange for meeting requirements around asset composition (typically ≥75% real estate), income sources (≥75% real-estate-related), and distribution levels (typically ≥90% of taxable income), REITs receive favorable pass-through tax treatment.

For investors, REITs provide access to real estate economics — rents, occupancy, lease escalators, and property appreciation — through publicly listed securities with daily liquidity. The structure also creates a strong dividend mandate, since the distribution requirement means REITs must regularly return cash.

“
Key takeaway
The REIT structure forces income distribution, which creates high yields but also limits retained capital for growth. REITs must often access capital markets (equity issuances, debt) to fund acquisitions — making balance sheet discipline and market cost of capital critically important.
Accounting

Why REITs require different metrics

The problem with applying standard corporate metrics to REITs is depreciation. GAAP requires companies to depreciate real estate assets over time (typically 27.5–39 years), which reduces reported net income even when the underlying properties are maintaining or increasing in value.

01
Worked example
Why net income understates REIT earnings
Rental revenue$500M
Operating expenses($150M)
Interest expense($100M)
Real estate D&A($180M)
Net income (GAAP)$70M
Add back: D&A+$180M
FFO$250M

Net income of $70M makes the REIT look like it barely earns anything. FFO of $250M reflects the actual recurring economic output. The $180M D&A charge is an accounting entry — not cash leaving the business.

Core metric

FFO — Funds From Operations

NAREIT definition of FFO
FFO = Net Income + Real Estate Depreciation − Gains on Property Sales + Impairments
Industry standard defined by NAREIT. Removes the distortion of D&A while excluding non-recurring gains.

FFO adjusts GAAP net income for real estate depreciation and property sale gains/losses. It is a widely used measure of recurring operating performance, though it is not fully standardized — companies apply slightly different definitions. Always read the reconciliation table in quarterly filings.

FFO is not cash flow
FFO does not subtract recurring capital expenditures (maintenance of properties, tenant improvement allowances, leasing commissions). This is why AFFO is generally preferred for dividend safety analysis.
Better metric

AFFO — Adjusted FFO (the dividend safety metric)

Common AFFO definition
AFFO = FFO − Maintenance Capex − Straight-line Rent Adjustments − Recurring Leasing Costs
Not standardized. Read each company's definition carefully. Some include/exclude different items.

AFFO goes further than FFO by subtracting recurring capex needed to maintain the property portfolio, leasing commissions, and straight-line rent adjustments (which inflate revenue for properties with stepped rent increases). AFFO is the closest approximation to distributable cash — the real basis for dividend safety analysis.

Why AFFO > FFO for dividends

FFO ignores the recurring cost of maintaining properties and renewing tenants. A net lease REIT may have minimal maintenance capex; a mall REIT may have very high tenant improvement costs. AFFO captures this difference.

The non-standardization problem

Unlike FFO, AFFO has no single industry definition. Some companies define it more generously (higher AFFO) than others. Always check the reconciliation and be skeptical of large unexplained adjustments.
Dashboard

The 8 metrics every REIT analyst tracks

FFO / AFFO per share
The core earnings metrics. Track trend, year-over-year growth, and payout ratio.
AFFO payout ratio
Dividends ÷ AFFO per share. Generally safe below 80–85% for most REIT types. High for net lease REITs (85–90%) is typical and acceptable.
Occupancy rate
The percentage of leasable space occupied. >95% is generally strong. Trends matter more than absolute levels.
Same-store NOI growth
Measures revenue growth from properties owned for >12 months — isolates organic growth from acquisitions.
Net Debt / EBITDA
Leverage metric. Most analysts prefer < 6–7× for investment-grade REITs. Above 8× creates refinancing risk.
Weighted average lease term (WALT)
Longer WALT = more income visibility. A REIT with 10-year average lease duration is far more predictable than one with 2-year leases.
Tenant concentration
If the top 3 tenants represent 60% of revenue and one is distressed, the dividend is at risk. Prefer diversified tenant bases.
Cost of capital spread
The gap between cap rates on acquisitions and the REIT's cost of debt/equity. Positive spread = accretive growth. Negative spread = value-destructive growth.
Pricing

How REITs are valued

P/FFO and P/AFFO

The most common REIT multiples. P/AFFO is preferred. Compare to historical range and sector peers. A net lease REIT at 15× P/AFFO is valued similarly to a stable bond-like business; a growth-oriented industrial REIT might trade at 25–30×.

P/NAV (Price to Net Asset Value)

Compares market price to estimated value of the underlying property portfolio less net debt. Trading at a discount to NAV can indicate value; a premium suggests growth expectations. NAV requires cap rate assumptions — a source of significant estimation risk.

Dividend yield vs. history

REITs with mandatory distribution requirements often have mean-reverting yields. A yield significantly above the 5-year historical average may indicate distress — or genuine opportunity if AFFO coverage is intact.

Implied cap rate

Enterprise value divided by NOI gives the implied cap rate the market is placing on the portfolio. Compare to prevailing direct real estate transaction cap rates to see whether the REIT is priced at a premium or discount to private market values.
Sector guide

REIT property sectors — quality varies dramatically

Property typeQuality profileKey dynamics
OfficeModeratePost-pandemic occupancy pressure; lease terms typically 5–10 years
Industrial / logisticsHighStructural tailwinds from e-commerce; high demand, low supply
Retail (strip / power)VariableGrocery-anchored is resilient; discretionary retail is challenged
Residential (multifamily)HighDurable demand; rent growth tied to wages and supply dynamics
Self-storageHighCounter-cyclical demand; very low capex; high margin
Healthcare / medicalModerateLong-term demographic tailwinds; tenant creditworthiness matters
Net lease (triple-net)HighTenant pays opex; very predictable income; low management overhead
Data centersVery HighDigital infrastructure demand; power and connectivity moats
Malls (regional)LowStructural decline; significant anchor risk; redevelopment optionality
◆Analyst note
Property type is one of the most important initial filters. Industrial and self-storage REITs have very different risk profiles from mall or office REITs, even at the same yield. A 7% yield from an industrial REIT looks very different from a 7% yield from a struggling mall REIT.
Risk

Main risks in REIT investing

Leverage and refinancing risk
REITs are frequent capital market participants — they must regularly refinance debt and issue equity. Rising interest rates increase refinancing costs and can make acquisition math unattractive, slowing external growth. Highly leveraged REITs face the additional risk of covenant breaches or forced asset sales.
Tenant quality and concentration
A REIT is only as safe as its tenants. A single large tenant that files for bankruptcy can trigger vacancy, capex for re-leasing, and a dividend cut all at once. Research the top 10 tenants, their credit ratings, and lease expiry schedules before investing.
Secular headwinds in certain sectors
Office and retail REITs face structural changes in demand that may not be cyclical. Permanently lower office utilization and e-commerce competition are not problems that recover automatically with the next economic expansion.
Questions

Frequently asked questions

REIT structures typically require distributing most taxable income. Combined with D&A-heavy financials that depress net income (creating the impression of high payout ratios), REITs often show elevated yields. But a high yield must always be tested against AFFO coverage, leverage, and tenant quality.
