Computed in exact decimal
A tested engine runs the math. AI proposes inputs for your review and never touches the arithmetic.
The workflow
From files to decision
Altyst reads what the broker sent and builds the full model. You review the inputs. The engine does the math.
01Intake
Start with the documents
Drop the offering memorandum, rent roll, T-12, debt quote, and lease schedule in whatever format they arrived in.

02Extract and reconcile
Documents checked against each other
Rent roll, trailing financials, and tenant schedule are extracted and then tied out against each other. Conflicts and low-confidence values come to you to settle.

04Debt and leasing
Structure debt and rollover
Size debt on LTV, minimum DSCR, or debt yield, then layer mezzanine, an interest-only period, or a bridge to refinance. Lease rollover carries TI, LC, downtime, renewal probability, and expense stops.

What you get
Every deal, three ways
The live underwriting
The model above, editable end to end. Every figure traces to a document.
The Excel workbook
Live formulas on every tab, from assumptions through sensitivities. Provenance and self-checks ship inside the file, and changing a cell recalculates it.
The memo and the deck
A one-page memo that makes the call to proceed, reprice, or pass, and shows where the deal is fragile. The deck comes editable, in PowerPoint or PDF.
The engine
Numbers you can defend
Every figure has a source
Click any number for its formula and the document it came from.
Edit anything, recompute everything
Change one input and returns, cash flow, debt, and downside all move.
Built for what you underwrite
Multifamily, office, retail, industrial, self-storage, mixed-use, and land, each with the leasing, debt, and waterfall it needs.
Break it before you bid
Base, upside, and downside side by side, with two-way grids on the drivers. Reprice in one click to the bid that hits your return.
Exports that reconcile
The workbook, the memo, the deck, and the lender and offering packages. Every figure in every file ties back to the engine, so what you send matches what you built.
Trust
What keeps it honest
Deterministic core
Results come from tested code, not a language model. AI reads the documents; each figure is flagged for your review, with its source and confidence.
Provenance and review
Extractions arrive with a source and a confidence. You can override any figure before the model relies on it.
Workspace isolation
Your deals and documents live in your workspace alone, behind role-based access and enforced separation.
Your data, deletable
Delete a deal, or the whole workspace, and the documents underneath are removed too.
