Pro Forma Pressure Test

What you get

A verdict you can hand to your committee

Enter your pro forma and the Pressure Test stresses every assumption — then returns a clean, white-labeled report built to make one call: build it, fix it, or pass.

The verdict, up top

Proceed, restructure, or pass — right beside the covenant scorecard: minimum DSCR, investor IRR and the funding gap. No digging required.

Where the deal breaks

Every driver ranked by how hard it pushes you toward a breach — plus a 4,000-run Monte Carlo showing the real probability the deal clears, not one tidy base case.

So anyone can read it

A plain-English glossary defines every term — DSCR, IRR, covenants, Monte Carlo — so your whole committee reads the same numbers the same way. Stress scenarios and full assumptions are in there too.

Your logo on the cover and your project's numbers throughout — only a small BuildLab credit stays locked in the footer.
Illustrative model. This pressure-test runs on a simplified, placeholder underwriting engine — loan sizing, equity timing and the IRR waterfall are stand-ins, not your funded terms. Use it to see how a deal bends under stress, not as a substitute for a fully underwritten pro forma. Talk to BUILDLAB to model your actual deal.

Tornado — driver sensitivity

Each bar spans the metric from −20% to +20% of the driver. Longest bar = sharpest knife.

Scenarios — bundled stress

Several drivers move together. This is where compounding failures surface that a single-variable sweep misses.

Loan sizing, equity timing and the IRR waterfall use placeholder logic — swap in your spec's math, then validate against a hand-underwritten deal before trusting any output.
