How to read a commercial real estate pro forma starts with accepting one honest fact: it's a sales document dressed up as a projection, and your job is to take it apart before you trust a single line.
What's Inside
How to read a commercial real estate pro forma comes down to a blunt, experienced-practitioner truth: every pro forma a buyer ever sees turns out to be wrong in some way, and that's not really a complaint, it's simply what a projection is.
The seller built the pro forma to sell the building. Your job, if you're the buyer or a passive investor, is to rebuild it to operate one.
Quick honesty note
This is education, not financial advice. Specific percentage thresholds below are commonly cited industry conventions, not fixed rules, and vary somewhat by asset class and market.
This assumes familiarity with NOI, cap rate, and going-in versus exit cap rate, covered in cap rate explained.
The Short Answer
In short: A pro forma is a multi-year projection, not actual results. Start by comparing Year 1 projected NOI against the trailing 12 months of actual performance; a large, unexplained gap is the single most common red flag.
Then check vacancy assumptions, expense growth relative to rent growth, the exit cap rate assumption, and whether a realistic management fee and capital reserves are included at all.
How a sponsor responds to your questions about these assumptions often tells you as much as the document itself.
What a Pro Forma Actually Is
A pro forma is a multi-year projection of a commercial property's income, operating expenses, debt service, and cash flow, built on a specific set of assumptions about rent growth, vacancy, expense growth, and an eventual exit, typically covering 5 to 10 years to match a realistic hold period.
It is a projection, not a record of actual results, and it's important to distinguish it from trailing 12-month (T-12) or year-end financials, which show what the property has actually done.
A seller's broker generally creates the marketing pro forma shown to prospective buyers; a sponsor building their own underwriting model should rebuild it independently rather than simply adopting the seller's assumptions.
The First Check: Year 1 Versus Trailing 12 Months
The single most revealing comparison in any pro forma is between the trailing 12 months of actual performance and the projected Year 1 numbers.
A large, unexplained jump in NOI from T-12 to Year 1 is one of the most common red flags in underwriting, a disciplined sponsor will show you exactly how they bridge that gap, unit by unit, whether through below-market leases rolling to market rate, a specific operational fix, or something else concrete and explainable.
If the explanation is vague or missing entirely, treat the projected number with real skepticism.
The Specific Red-Flag Checklist
- Vacancy assumed below 5%. Most disciplined pro formas model economic vacancy, covering both physical vacancy and credit loss from non-paying tenants, commonly in the 5-10% range depending on asset class and market.
- Expense growth assumed lower than rent growth. This is an internally inconsistent assumption that quietly inflates NOI over the projection period.
- Rent growth above roughly 4-5% annually without supporting market data. Ask what actual rent trends in this specific submarket have looked like over the past three years, and what the forward new-supply pipeline looks like before accepting an aggressive number.
- Exit cap rate equal to or lower than the going-in cap rate. No one can predict cap rates years in advance, and assuming today's pricing environment holds or improves is optimism embedded directly into the projected return.
- Management fee missing entirely, or below roughly 3% of effective gross income. Even a self-managed or affiliated-management structure has a real cost that belongs in the model.
- No replacement reserves, or a capital expenditure budget that's a suspiciously round number with no line items. A real capex plan should be built from specific, identifiable items, not a single tidy figure that looks convenient rather than researched.
Seller-side rent growth conventions often run around 3% annually or an inflationary assumption applied throughout the entire hold period, while more disciplined buyer-side underwriting commonly assumes flat rent growth for the first year or two before applying an inflationary rate thereafter, a meaningfully more conservative posture that compounds into a real difference in projected exit value.
How the Sponsor Talks Matters as Much as What They Show You
Some of the most useful signals aren't in the numbers at all. Language that leans heavily on urgency, exclusivity, or a fear of missing out can suggest a sponsor prioritizing momentum over genuinely informing you, while clear, measured language without hype often signals confidence in the underlying deal.
Sophisticated sponsors tend to acknowledge risk upfront rather than hiding it, and they can explain specifically how value will be created rather than relying on vague phrases.
Defensiveness, vagueness, or pressure to move quickly when you ask a direct question about an assumption is a signal worth taking seriously, sometimes the biggest red flag isn't in the document at all, it's in how your questions get handled.
The Three-Minute Verification Step
For a syndicated deal, every Regulation D offering under the common exemptions is required to file a Form D on SEC EDGAR within 15 days of the first investor commitment.
If a sponsor tells you a deal is actively raising capital and you cannot find a corresponding Form D, that alone is worth pausing on.
It takes a few minutes to check, confirms the offering type and the amount being raised, and identifies the principals behind the entity, a small step that's easy to skip and genuinely worth doing every time.
Common Mistakes (and How to Dodge Them)
- Accepting a pro forma's Year 1 numbers without comparing them to T-12 actuals. This single comparison surfaces more inflated assumptions than almost any other check.
- Not questioning an exit cap rate at or below the going-in rate. This assumes the market stays exactly as favorable as it is today, indefinitely.
- Overlooking a missing or understated management fee and capital reserves. These costs are real regardless of whether the pro forma accounts for them.
- Focusing only on the numbers and ignoring how the sponsor communicates. Defensiveness or urgency when you ask questions is meaningful information on its own.
- Skipping the Form D check on a syndicated deal. It takes minutes and confirms basic facts about the offering that should be easy to verify.
Frequently Asked Questions
What is the first thing to check when reading a commercial real estate pro forma?
Compare the projected Year 1 NOI against the trailing 12 months of actual performance. A large, unexplained gap is one of the most common signs of overly optimistic assumptions.
What vacancy rate should a realistic pro forma assume?
Most disciplined pro formas model economic vacancy, covering both physical vacancy and credit loss, commonly in the 5-10% range. A vacancy assumption below 5% deserves closer scrutiny.
Is it a red flag if the exit cap rate equals the going-in cap rate?
It can be, especially in an uncertain rate environment. No one can reliably predict cap rates years in advance, so an exit assumption that matches or improves on today's rate embeds real optimism into the projected return.
How can I tell if a sponsor's rent growth assumption is unrealistic?
Ask for actual rent trends in the specific submarket over the past three years and what the forward new-supply pipeline looks like. Rent growth assumptions above roughly 4-5% annually generally deserve supporting market data before being accepted.
What is a Form D and why does it matter for a real estate syndication?
It's a filing on SEC EDGAR required for most private securities offerings within 15 days of the first investor commitment. If a sponsor says a deal is actively raising and no Form D appears, that's worth investigating before committing capital.
Does a high projected return automatically mean a pro forma is unrealistic?
Not automatically. High projected returns aren't inherently a problem, but the underlying assumptions driving them need to be reasonable and well-supported. Unrealistic assumptions, not high numbers on their own, are the actual red flag.
Rebuild It Before You Trust It
How to read a commercial real estate pro forma comes down to treating it as a starting point for your own analysis, not a finished answer.
Check Year 1 against T-12 actuals, scrutinize vacancy, rent growth, and exit cap rate assumptions specifically, confirm a real management fee and capital reserves are included, and pay attention to how the sponsor responds when you ask direct questions about any of it.
