Workflow comparison

General AI can answer questions. Cactus keeps underwriting work connected.

The gap is not raw intelligence. The gap is whether the package, source trail, assumptions, reviewer decisions, model output, and memory survive after the first response.

One-time AI

Fast thinking from a blank page.

  • A prompt, a pasted file, and an answer that can drift from the source.
  • Helpful if the team remembers to ask where each number came from.
  • Discussed in a chat, then rebuilt by the analyst inside the model.
  • Draft support that still needs a separate model and separate handoff.
Cactus

Analyze. Prove. Remember. Handoff.

  • OMs, rent rolls, T-12s, leases, and spreadsheets become a reviewable deal package.
  • Key facts stay tied to page context, confidence, timestamp, and reviewer state.
  • Editable assumptions sit beside comps, market context, and team approval.
  • Excel-ready analysis, IC support, lender review, BOV support, and reusable firm context.
Product walkthrough

Follow one deal from intake to Proprietary Memory.

Input

Drop in the materials your team already receives.

Start with the OM, rent roll, T-12, lease files, broker notes, lender package, spreadsheet model, or market export. Cactus organizes the deal package before the model changes.

Process

Extract facts with the source trail still attached.

The workspace shows the number, source, confidence, timestamp, and state. Analysts are not asked to trust a summary without seeing where it came from.

Review

Put assumptions beside comps, market context, and team judgment.

Cactus does not hide the model. It gives the team a review surface where rent growth, taxes, insurance, cap rates, debt, and comp support can be accepted, changed, or flagged.

Output

Move approved work into Excel, IC support, and lender review.

When the team approves the assumptions, the work becomes an editable handoff with source context still attached, not a static AI answer floating outside the workflow.

Memory

Save the approved logic into Proprietary Memory.

Approved facts, comps, templates, and decisions become reusable firm context so the next multifamily or self-storage deal starts with what the team already knows.

What changes

Underwriting becomes a reusable workflow, not another disconnected output.

Cactus can combine uploaded materials with approved market sources, customer-owned exports, internal comp history, public records, and analyst review where permitted.

From deal package to reviewed facts

Rent roll and T-12 line items

Upload OMs, rent rolls, T-12s, leases, spreadsheets, lender packages, broker notes, and market context. Cactus organizes the package into facts your team can inspect before the model changes.

From line item to market support

Rent comps and sales comps

Rent comps, sales comps, cap-rate support, debt terms, public records, taxes, flood and zoning context, and approved market-source data can sit beside the assumptions they influence.

From analyst edit to approved assumption

Cap rates, debt terms, taxes, and insurance support

Analysts, principals, brokers, and credit teams can change, approve, or reject assumptions while the source context and reviewer state remain visible.

From one model to Proprietary Memory

Supply, demographics, flood, zoning, and public-record context

Approved facts, comps, templates, and review decisions can become reusable firm context, so future deals do not start from an empty chat or a forgotten folder.
