ARGUS Enterprise and Excel are not two versions of the same tool. ARGUS Enterprise, per Altus Group's own description, is software for modeling a property's cash flow and valuing it. Excel is a general spreadsheet that can model anything, including nothing, depending on who built the workbook. The right choice depends on how complex the asset is, who will read the result and how much control you need over every cell.

The comparison at a glance
| Feature | ARGUS Enterprise | Excel |
|---|---|---|
| What it is | Software for property cash flow modeling and valuation (Altus Group's description) | General spreadsheet |
| Structure | Lease-based asset model with defined inputs | Whatever the author builds |
| Valuation methods | Discounted cash flow and capitalization approaches, per Altus Group | Any method you can write as formulas |
| Scenarios | What-if and sensitivity analysis, per Altus Group | Data tables and scenario tabs you build |
| Review | Familiar format that counterparties may expect | Open to inspection, but each model is different |
| Pricing | Tiered subscription, no list price on the page we read | Usually already installed on the desk |
| Risk | Setup time and a learning curve | Hidden errors; inconsistent models between analysts |

When ARGUS is the right tool
- Multi-tenant assets where lease terms, reimbursements, renewals and free rent drive value.
- Institutional settings where lenders, auditors or investors expect a recognized model.
- Portfolios that need consistent structure across many assets.
When Excel is the right tool
- A fast screen on a property that will probably not be bought.
- Single-tenant or simple multifamily where a lease-by-lease model adds little.
- Unusual structures, such as a development with phased income, where you need to write the logic.
- Teams that already maintain a disciplined, version-controlled model.
What fails in a spreadsheet
A model that works can still mislead. The failures that matter are procedural: a number typed over a formula, a rent roll that was never reconciled with the T-12, last deal's cap rate left in a cell, and no note of where an input came from. If an analyst leaves, the next person inherits cells without reasons. Both ARGUS and Excel need review. ARGUS constrains the structure; Excel leaves it to you.
Where AI helps in either workflow
AI shortens the least interesting part: getting clean inputs into the model. Titleman reads the OM, rent roll and T-12, checks them against each other and the market, and returns a live-formula Excel model in which every input shows its source and date and every result shows its formula. Measured over the 30 days to 18 October 2026, the median underwriting took about 58 minutes from request to delivered files. We have no measured baseline for the same work by hand.
That workbook can be a starting point for your own Excel template or for the assumptions you carry into ARGUS. See Titleman vs ARGUS Enterprise.
What none of these replace
- A licensed appraisal where required.
- Title, environmental and engineering diligence.
- Your view on rents, exit and risk.
Titleman's memo states no final price or buy or sell verdict, and it underwrites the property, not the borrower. To test the workbook on a property you know, request access.
