The projected financial performance of a deal — what could be.
A pro forma is a projected financial statement for a real estate investment — typically projecting income, expenses, NOI, debt service, and cash flow for a stabilized or post-renovation operating period. Pro formas underpin every commercial real estate investment decision, but they're also the most consistently overstated documents in the industry.
A pro forma serves two distinct purposes that often conflict. From the seller's perspective, a pro forma is a marketing document — designed to show the property's potential at its highest reasonable interpretation. Rents are at the top of market range, vacancy at the bottom, expenses at the lowest reasonable level. The seller's pro forma usually produces a higher value than trailing financials would support.
From the buyer's perspective, a pro forma is a diligence tool — the basis for underwriting whether the deal will perform as advertised. Sophisticated buyers haircut the seller's pro forma aggressively: rents reduced to median market (not top), vacancy increased to historical norms, expenses stress-tested with actual vendor quotes and tax reassessment risk. The buyer's pro forma usually produces a value 5–15% below the seller's.
Lenders take an even more conservative approach. Most lenders underwrite to trailing 12-month performance — not pro forma — for purposes of sizing senior debt. Pro forma assumptions are only used for forward DSCR and debt yield tests on transitional deals where the asset isn't yet stabilized. Lenders have seen too many "stretched" pro formas to take them at face value.
For investors, the discipline of building a realistic pro forma is everything. Start with trailing actuals (not pro forma). Apply market-supported rent assumptions (use comps, not seller projections). Use conservative vacancy (market average minimum). Stress-test all major expense categories with actual vendor quotes. And model the realistic stabilization timeline, not the best-case. Conservative pro forma underwriting is what makes the difference between a deal that delivers and one that doesn't.

A projected financial statement showing the expected performance of a real estate investment — usually at stabilization or post-renovation. The basis for valuation and underwriting decisions.
Sellers market their property at the highest reasonable interpretation — top-of-range rents, optimistic vacancy, minimum expenses. The pro forma supports a higher asking price than trailing actuals would justify.
Start with trailing 12-month actuals. Apply market-supported rent assumptions (use closed comps, not seller projections). Use conservative vacancy (market average minimum). Stress-test all expense categories.
Most senior lenders underwrite to trailing 12-month performance, not pro forma. Pro forma is used for forward DSCR / debt yield tests on transitional deals (bridge, value-add) where the asset isn't yet stabilized.
T-12 is actual trailing performance — verifiable from operating statements. Pro forma is projected future performance — a model, not actuals. T-12 is what is; pro forma is what could be.
Matrix underwrites loans on trailing performance and realistic stabilized projections — so the loan that funds reflects what the property can actually do.
