Commercial Real Estate Underwriting Software Built for Acquisitions Teams

Commercial real estate underwriting software is a purpose-built platform that takes raw property data — rent rolls, expenses, loan terms, market assumptions — and generates the financial outputs investors and lenders need to evaluate a deal. That includes annual and monthly proforma statements, net operating income (NOI), debt service coverage ratio (DSCR), loan-to-value (LTV), leveraged and unleveraged IRR, and exit scenario analysis. Solsten is a cloud-based commercial real estate underwriting software that handles all of these in one workflow.

Excel proformas break silently when assumptions change. A formula reference shifts, a tab gets deleted, an inflation rate gets typed into the wrong cell — and the IRR you submit to your investment committee is wrong. Purpose-built real estate underwriting software like Solsten enforces the math, tracks assumption provenance, and re-runs every dependent calculation automatically when an input changes. The result is fewer errors, faster deal turnaround, and an audit trail you can defend.

Multifamily underwriting software has to model unit-level rent rolls (often hundreds of leases), turnover and vacancy assumptions per unit type, rent growth that varies by submarket, expense ratios that differ from commercial property types, and renovation/value-add scenarios that change the rent schedule mid-hold. Solsten supports multifamily underwriting alongside office, retail, industrial, and mixed-use — with tenant lifecycle modeling, market rent escalation, and exit cap rate sensitivity across every hold year.

Commercial real estate analysis software is used to convert deal assumptions into the metrics that drive go/no-go decisions: IRR, equity multiple, cash-on-cash return, DSCR, break-even occupancy, debt yield, and stress-tested downside cases. It also covers comparative analysis — multiple properties side by side, multiple scenarios per property, and exit-year optimization. Solsten provides commercial real estate analysis software with 15-factor risk scoring and scenario sensitivity built into every property model.

About 10 minutes for a typical property. Solsten uses 10 guided input pages — property details, rates, expenses, recoveries, market assumptions, tenants, revenues, financing, and investment structure. Excel T-12 import shortens expense entry. After inputs are in, the proforma, DCF, waterfall, and risk score generate automatically. Compare that to several hours per deal in Excel or a multi-day setup in legacy enterprise software.

Yes. Solsten reads ARGUS Enterprise rent roll and expense exports directly, with auto-detection of suite, tenant name, leased area, base rent PSF, lease commencement and expiration, escalation, recovery type, and more. It also imports T-12 operating statements from Excel or CSV via a 4-step wizard with smart column mapping. See the /argus-alternative/ page for the full ARGUS migration walkthrough.

Solsten supports office, retail, industrial, multifamily, mixed-use, medical office, and flex properties. The underwriting engine handles property-type-specific assumptions: NNN/Base Year/Modified Gross recovery structures for commercial, unit-level rent rolls for multifamily, anchor/in-line tenant splits for retail, and dock/clear-height adjustments for industrial.

Yes. Solsten generates GP/LP waterfall distributions with multi-tier promote structures, preferred returns, catch-up provisions, and lookback IRRs. Investor-ready reports cover unleveraged and leveraged IRR, equity multiple, distributions by year, and exit scenarios. The waterfall engine ties back to the same proforma cash flows the underwriting model is built on — no separate reconciliation step.
