How to Evaluate a REIT: FFO, AFFO & NAV

Because GAAP net income systematically understates a REIT's true earnings, primarily due to depreciation. Under accounting rules, a REIT depreciates its buildings over time, recording a large non-cash depreciation expense that reduces reported net income each year. But real estate often holds or grows its value rather than declining — so the depreciation charge does not reflect a real economic loss the way it might for a wasting asset like equipment. Because depreciation is such a large expense for a property-heavy business, net income can be a poor measure of a REIT's actual cash-generating ability — a REIT can report modest or even negative net income while generating substantial cash. So relying on net income (or a standard P/E ratio) to evaluate a REIT is misleading. This is why the industry developed metrics like FFO and AFFO that add back real estate depreciation to better reflect the cash the REIT actually produces. So use the purpose-built REIT metrics, not ordinary net income, to evaluate a REIT's earning power.

FFO stands for funds from operations, the foundational REIT earnings metric and the Nareit (National Association of Real Estate Investment Trusts) industry standard. FFO is calculated by taking GAAP net income, adding back real estate depreciation and amortization (the large non-cash charges that distort net income), and subtracting gains on property sales (which are one-time, not recurring operating income), with some additional adjustments per the Nareit definition. So FFO = net income + real estate depreciation and amortization − gains on property sales. The logic is to strip out the non-cash depreciation distortion and the non-recurring sale gains, leaving a measure that better reflects the recurring cash earnings from the REIT's operating properties. So FFO is a far more meaningful earnings measure for a REIT than net income — it is the metric analysts and the industry use to gauge operating performance. The P/FFO ratio (price divided by FFO per share) is the REIT equivalent of a P/E ratio, used to compare valuations across REITs. FFO is the first metric to learn for REIT analysis.

FFO is calculated by starting with GAAP net income and making two main adjustments: adding back real estate depreciation and amortization, and subtracting gains (or adding back losses) on the sale of properties. The Nareit definition includes some additional adjustments, but the core formula is: FFO = net income + real estate depreciation and amortization − gains on property sales. Adding back depreciation corrects the central distortion (the large non-cash charge that depresses net income even though real estate often appreciates), and removing property-sale gains strips out one-time items that are not recurring operating income. The result better reflects the recurring cash earnings from the REIT's operating properties. REITs report FFO in their filings, and you can compute FFO per share by dividing by shares outstanding. So FFO is net income adjusted to add back depreciation and remove one-time sale gains — a measure of recurring operating earnings. Always check how a specific REIT defines and reconciles its FFO, since there can be minor variations, but the Nareit standard provides the common framework.

AFFO stands for adjusted FFO, a refinement of FFO that gets closer to the true cash a REIT has available to distribute. While FFO adds back depreciation, it does not account for the real, recurring capital a REIT must spend to maintain its properties, or for certain accounting smoothing of rent. AFFO adjusts for these: it takes FFO and subtracts recurring maintenance capital expenditures (the ongoing capex needed to keep properties competitive) and straight-line rent adjustments (an accounting smoothing of lease income). So AFFO = FFO − recurring/maintenance capex − straight-line rent adjustments, with some variation across REITs. The result is a measure closer to the actual cash available for distribution to shareholders, because it accounts for the real ongoing spending FFO ignores. So AFFO is often considered a better gauge of a REIT's sustainable distribution capacity than FFO. The trade-off is that AFFO definitions vary across REITs (there is no single standardized formula), so comparisons require care. Use AFFO to assess whether distributions are supported by real, sustainable cash flow.

NAV stands for net asset value — a measure of what a REIT is worth from a balance-sheet perspective, the value of its properties net of its debts. NAV is calculated by estimating the current market value of the REIT's real estate (and other assets), subtracting its liabilities (debt and obligations), and dividing by the shares outstanding to get NAV per share. So NAV per share represents the estimated underlying value of the REIT's net assets attributable to each share. NAV is useful for gauging whether a REIT's shares trade at a premium or a discount to the value of its properties: if a traded REIT's share price is below its NAV per share, the shares trade at a discount (potentially cheap relative to the underlying real estate); if above, at a premium. For non-traded REITs, the periodic NAV is the basis for the share value and redemption pricing. So NAV provides an asset-based valuation reference distinct from the earnings-based FFO and AFFO — a balance-sheet view of value against the underlying real estate. NAV estimates carry some uncertainty, since they rely on appraisals and assumptions.

P/FFO is the price-to-FFO ratio — a REIT's share price divided by its FFO per share — and it is the REIT equivalent of the price-to-earnings (P/E) ratio used for ordinary stocks. Because FFO is the meaningful earnings measure for a REIT (correcting net income's depreciation distortion), P/FFO is the appropriate valuation multiple for comparing REITs. A lower P/FFO suggests a REIT is priced more cheaply relative to its FFO earnings; a higher P/FFO suggests a richer valuation, which the market may justify by faster growth or higher property quality. So you use P/FFO much as you would use P/E for a stock — to compare valuations across REITs and against historical norms, ideally among REITs of similar property type and quality. Do not use a standard P/E ratio for a REIT, since net income is distorted by depreciation; P/FFO is the correct tool. Combine P/FFO with AFFO-based distribution analysis and NAV (premium/discount) for a fuller valuation picture, since P/FFO alone, like any single multiple, does not capture distribution sustainability, leverage, or asset value.

A REIT trading at a discount to NAV means its share price is below the estimated per-share value of its net assets (its properties less liabilities). In principle, this suggests the market is valuing the REIT for less than its underlying real estate would be worth — potentially indicating the shares are cheap relative to the assets. A premium to NAV means the opposite: the share price exceeds the per-share asset value, suggesting the market is paying up (perhaps for growth, quality, or management). However, discounts and premiums should be interpreted carefully: a persistent discount may reflect real concerns (poor management, bad assets, high leverage, or sector headwinds) rather than a bargain, and NAV itself is an estimate based on appraisals and assumptions, so it carries uncertainty. So a discount to NAV is a signal worth investigating, not an automatic buy — examine why the discount exists and whether the NAV estimate is reliable. Use the premium/discount to NAV alongside FFO, AFFO, debt, and qualitative analysis, rather than in isolation, to judge whether a REIT is genuinely undervalued.

The key check is the payout ratio against AFFO — comparing the distribution per share to AFFO per share. Because AFFO approximates the true cash available for distribution (after accounting for maintenance capex and rent smoothing that FFO ignores), comparing the distribution to AFFO tells you whether the distribution is covered by sustainable cash flow. A payout ratio comfortably below 100% of AFFO suggests the distribution is supported by real cash with a cushion; a ratio at or above AFFO is a warning that the distribution may not be sustainable and could be cut. You can also look at the FFO payout ratio, but AFFO is the more conservative, cash-focused gauge. Beyond the ratio, consider how the distribution has trended, whether any portion is funded by return of capital or borrowing (less sustainable), and the REIT's growth prospects. So to assess distribution sustainability, focus on the AFFO payout ratio (is the distribution covered by real cash?), the funding sources, and the trend — a high payout near or above AFFO signals risk. A sustainable distribution is covered by AFFO with room to spare.

Debt levels matter because REITs use leverage, and leverage amplifies both returns and risk. A REIT borrows to acquire properties, so its debt profile is central to its risk. Key things to examine: the leverage ratio (debt relative to assets or to a cash-flow measure like EBITDA), which shows how much the REIT relies on borrowing; the debt-maturity schedule (when debt comes due and whether it must be refinanced, possibly in a difficult or high-rate market); and interest costs (which reduce cash flow and rise with rates on variable or maturing debt). High leverage magnifies gains in good times but also losses in downturns, and near-term maturities create refinancing risk if credit conditions tighten. So a REIT's debt is a key part of its risk assessment, alongside the earnings (FFO) and asset (NAV) metrics. A REIT with high leverage and looming maturities is riskier than one with moderate, well-laddered debt, even at similar FFO. So always examine the debt profile when evaluating a REIT — it can turn an otherwise attractive REIT into a risky one, or provide reassurance about resilience.

Yes — REITs are generally sensitive to interest rates, which matters when you evaluate them. Higher rates can affect REITs in several ways: they raise the REIT's borrowing costs (especially on variable-rate or maturing debt that must be refinanced), reducing FFO and AFFO; they can pressure property values (and thus NAV), since real estate is often valued by capitalizing income at a rate tied to interest rates; and they make a REIT's yield compete with higher yields on bonds and cash, which can weigh on traded REIT share prices. Conversely, falling rates can be supportive. So when evaluating a REIT, consider its interest-rate exposure — the share of variable-rate debt, the debt-maturity schedule (near-term maturities are more exposed to refinancing at higher rates), and the sector's rate sensitivity. This ties back to the debt analysis and to NAV: a REIT with a strong, well-laddered, mostly fixed-rate balance sheet is more resilient to rising rates than one with heavy near-term, variable-rate debt. So factor interest-rate sensitivity into your evaluation alongside FFO, AFFO, NAV, and debt — it is a key part of a REIT's risk profile and can significantly affect both earnings and valuation over time.

No — no single metric tells the whole story, and relying on one can mislead you. FFO shows recurring earnings but not distribution sustainability or asset value. AFFO is closer to distributable cash but its definition varies across REITs. NAV gauges premium or discount to assets but is an estimate based on appraisals. The yield alone says nothing about whether the distribution is sustainable or how much risk you are taking. So sound REIT evaluation uses the metrics together: P/FFO to gauge earnings and valuation, the AFFO payout ratio to assess distribution sustainability, and NAV to judge premium or discount — plus debt levels and qualitative factors (property type and quality, occupancy, lease terms, management, growth prospects). Each metric covers a different dimension, and combining them gives a rounded picture no single number provides. So treat FFO, AFFO, NAV, payout ratios, and debt as a toolkit, not a single verdict, and add qualitative judgment about the business. A high yield or low P/FFO in isolation can hide real problems that the full set of metrics would reveal.

Yes — REITs typically report FFO (and often AFFO) in their financial filings and earnings releases, along with reconciliations to GAAP net income, because these metrics are the industry standard for communicating REIT performance. FFO follows the Nareit definition, which provides a common framework, so reported FFO is reasonably comparable across REITs (though you should still check each REIT's reconciliation for any variations). AFFO is less standardized — REITs may label it AFFO, FAD (funds available for distribution), or CAD (cash available for distribution), and the specific adjustments (which capex counts as recurring, how rent is adjusted) can vary — so AFFO comparisons across REITs require care to ensure you are comparing like with like. NAV is sometimes provided by the REIT (especially non-traded REITs, which report a periodic NAV) and sometimes estimated by analysts. So you can generally find FFO and AFFO in a REIT's reporting, but read the definitions and reconciliations, since the labels and adjustments are not perfectly uniform. So use the REIT's reported figures as a starting point, verify the methodology, and be cautious comparing AFFO across REITs with different definitions.

Not necessarily — higher FFO is generally good, but FFO must be considered in context. FFO measures the level of recurring earnings, but evaluation also depends on the price you pay (P/FFO valuation), the growth rate of FFO (a REIT with growing FFO is more attractive than one with flat or declining FFO at the same level), the sustainability of distributions (AFFO payout ratio), the asset value (NAV premium or discount), and the risk (debt levels, property quality). So a high FFO at a high price (high P/FFO) may be less attractive than a moderate FFO at a low price. And FFO growth matters as much as the absolute level — a REIT whose FFO per share is rising is creating value, while one whose FFO is shrinking (perhaps from dilution or declining properties) is not, regardless of the current level. So do not look at FFO in isolation or assume higher is always better; consider FFO per share, its growth, the valuation multiple, and the other metrics together. The goal is sustainable, growing FFO per share at a reasonable valuation, with sound distribution coverage and manageable debt — not simply the highest FFO.

Beyond FFO, AFFO, and NAV, several qualitative factors are central to evaluating a REIT. Property type and quality — different sectors (e.g., industrial, residential, retail, office, healthcare, data centers) have different dynamics, and higher-quality, well-located properties tend to be more resilient. Tenant and lease profile — occupancy rates, lease lengths, tenant credit quality, and rent escalators affect income stability. Management quality and track record — experienced, aligned, shareholder-friendly management matters greatly. Growth prospects — the REIT's pipeline, markets, and ability to grow FFO per share. Balance-sheet strength — beyond raw leverage, the cost and structure of debt and access to capital. And the broader sector and economic backdrop — interest-rate sensitivity and demand trends for the property type. So the metrics are tools within a broader analysis, not a substitute for judgment about the business. So combine the quantitative metrics (FFO, AFFO, NAV, payout, debt) with these qualitative factors for a complete evaluation. A REIT with strong metrics but weak assets, management, or sector outlook may be less attractive than the numbers alone suggest.
