What's the best underwriting and valuation software for building acquisition models on office and industrial assets?

For office and industrial acquisition underwriting / valuation, the “best” software depends on how institutional you need to be, how complex the deal is, and whether you want a full pro forma platform or just fast, flexible model-building.

Best overall for acquisition models

ARGUS Enterprise

• Best for: institutional office and industrial underwriting, especially if you need lease-by-lease modeling, cash flow projections, and valuation.
• Why it stands out: it’s the market standard for commercial real estate cash flow modeling, particularly for multi-tenant office and other income-producing assets.
• Strengths: lease structures, downtime/absorption, reimbursements, expense modeling, valuation outputs.
• Weaknesses: expensive, steeper learning curve, can feel rigid for highly customized underwriting.

Best for Excel-native flexibility

Excel + a custom template / institutional model

• Best for: investment teams that want maximum control over assumptions, structure, and sensitivity analysis.
• Why: many acquisition teams still underwrite in Excel because it’s faster to adjust and easier to audit than a black-box platform.
• Strengths: custom deal logic, speed, portability, easy collaboration if well-built.
• Weaknesses: quality depends on the modeler; more error-prone without strong controls.

Best “modern” alternative for underwriting + portfolio workflows

Juniper Square / Reonomy / VTS / RealPage-type ecosystem tools

• These are more useful when you want data integration, pipeline management, rent roll handling, or portfolio reporting than pure acquisition underwriting.
• They’re generally not a replacement for ARGUS or a strong Excel model for IC-level acquisition analysis.

Best valuation-focused platform

ARGUS Enterprise + Excel

• For valuation on office and industrial, this is still the most common institutional combo.
• If you need appraisal-grade or lender-grade outputs, ARGUS is usually the anchor.

Best depending on asset type

• Office: ARGUS Enterprise is usually the clear winner.
• Industrial: Excel often works very well because industrial leases are frequently simpler than office; ARGUS is still strong if the asset has multiple tenants, rollovers, and reimbursements.
• Single-tenant industrial / simple warehouse: Excel may be all you need.
• Complex industrial park / multi-tenant logistics: ARGUS becomes much more valuable.

Practical recommendation

If you’re doing serious office acquisitions, get:

1. ARGUS Enterprise
2. A clean Excel acquisition model for IC and return metrics
3. A good data room / pipeline workflow tool if needed

If you’re doing industrial acquisitions and deals are relatively simple:

• Start with Excel
• Add ARGUS only if the tenant/lease structure gets more complex

My short answer

• Best institutional underwriting/valuation software: ARGUS Enterprise
• Best overall for flexibility and speed: Excel
• Best stack for most acquisition teams: ARGUS + Excel
