Commercial Real Estate Underwriting Software That Starts From the Documents
Underwriting software automates the path from a data room to a decision: extract the financials from rent rolls and leases, reconcile income honestly, model the debt, and stress the assumptions. EVALUAITE builds that entire path from the documents you upload — with every figure traceable back to its source.

The Five Layers of an Underwrite
1. Document extraction. The underwrite is only as good as its inputs, and the inputs live in PDFs. AI lease abstraction reads rent rolls, leases, and operating statements into structured data — the layer where manual underwriting burns most of its hours.
2. Income reconciliation. Commercial documents routinely disagree — the rent roll says one thing, the operating statement another, and both carry in-place and stabilized bases. Underwriting software should reconcile them explicitly and tell you which income basis each metric is built on, because a cap rate quoted on the wrong basis is a mispriced deal.
3. The model. NOI, cap rate, cash flow, multi-year projections — and strategy-aware structure: a value-add deal needs rehab, holding, and refinance phases; a development deal starts from land and construction. One flat template can't model four deal shapes. See how to build a real estate proforma for the anatomy.
4. The debt. Loan sizing against DSCR floors (check yours here), refinance scenarios, and — for Canadian multifamily — CMHC MLI Select premiums and tier gates modeled natively. Debt structure decides more deals than price does.
5. The stress test. Sensitivity analysis across vacancy, rates, and exit assumptions — because deals rarely fail everywhere at once; they fail in the one assumption nobody tested. Reverse valuation answers the buy-side version: what's the most I can pay and still hit my constraints?
Where EVALUAITE Fits
EVALUAITE covers all five layers in one workflow: upload the deal documents, AI extracts and reconciles the financials (with per-document source tracking), and the strategy-aware proforma engine builds the model — buy-and-hold, value-add, disposition, or development — with CMHC scenarios, sensitivity analysis, and report generation on top. It works entirely from your documents, so off-market and private deals underwrite as easily as listed ones.

Frequently Asked Questions
What does commercial real estate underwriting software do?
It turns a deal's raw inputs — rent rolls, leases, operating statements, financing quotes — into a decision: what the property earns, what it should trade at, and whether the deal works at your price and structure. Modern platforms automate the mechanical layers (document data extraction, income reconciliation, model assembly) so the analyst's time goes to the assumptions that actually need judgment.
How is automated underwriting different from a spreadsheet?
A spreadsheet starts empty every time and every number is typed in by hand — which is where transcription errors and stale-template bugs live. Underwriting software starts from the documents: data is extracted once, reconciled against source, and flows into a model whose math is tested code rather than inherited formulas. The spreadsheet skill doesn't disappear; the re-keying does.
What should underwriting software handle for Canadian deals?
CMHC-insured financing is the big one: MLI Select's points tiers change maximum LTV, amortization, DSCR floors, and insurance premiums, and a model that can't represent them misprices most Canadian multifamily deals. EVALUAITE models CMHC premiums and MLI Select scenarios natively, alongside conventional structures.
Does underwriting software replace the analyst?
No. It replaces the transcription and assembly work — reading documents into data, building the first-pass model, flagging inconsistencies. Which income basis to underwrite, how to weight comparables, and what a risk is worth remain human calls. The honest pitch is time reallocation, not replacement.
What does 'defensible underwriting' mean in practice?
Every number in the model traces to a source: a rent from the rent roll, an expense from the operating statement, a term from the lease. That's the standard a lender or investment committee holds you to, and it's the design principle behind EVALUAITE's extraction — figures carry their provenance, and anything the AI can't read confidently is flagged rather than guessed.
How much does commercial real estate underwriting software cost?
Enterprise platforms are typically custom-priced per seat or per portfolio. EVALUAITE uses flat monthly tiers — free to evaluate, Solo at $79/month, Team at $199/month, Business at $399/month — with document extraction, the proforma engine, CMHC modeling, and market intelligence included in one subscription.
