Solsten 2026 Review: Details, Pricing & Features

Solsten Overview

Solsten is an end-to-end commercial real estate investment platform designed for small- to mid-sized owner-operators who need institutional-grade underwriting and reporting without the complexity of enterprise software.

Solsten is developed by Nordic Real Estate Services, a U.S. veteran-owned company focused on building institutional-grade CRE analysis tools for owner-operators.

The platform spans the full lifecycle of a property—from acquisition analysis through ongoing asset and portfolio management—allowing users to transition seamlessly from underwriting to live operations. Unlike traditional tools that silo analysis, asset management, and investor reporting, Solsten consolidates these functions into a single system.

A core differentiator is its architectural philosophy: while AI is used to accelerate onboarding and user workflows, Solsten relies on deterministic financial engines to power calculations and investment outputs. This ensures consistent, repeatable results—an important distinction in a market increasingly saturated with “black box” AI tools.

Pros Explained

Institutional-grade underwriting without enterprise complexity: Solsten delivers many of the advanced modeling capabilities traditionally associated with enterprise CRE software while maintaining a significantly simpler user experience. The platform combines underwriting, operating statements, lease modeling, financing analysis, and waterfall structures into a single workflow, reducing reliance on disconnected spreadsheets and legacy tools.

Deterministic calculation engine improves transparency: A key differentiator is Solsten’s deterministic engine—meaning identical inputs always produce identical outputs. This contrasts with AI-driven “black box” tools that may introduce inconsistencies. The platform uses centralized single-source-of-truth (SSOT) calculation frameworks across inflation, occupancy, projections, and waterfall distributions to ensure accuracy and repeatability.

Built-in audit trails and version transparency: Every action within the system is logged, versioned, and traceable. Users can view historical states, track changes, and identify who made specific updates, enhancing internal controls and investor trust.

AI-powered onboarding and guided workflows: While calculations remain deterministic, AI accelerates onboarding. New users can generate example properties and receive guided walkthroughs, significantly reducing the learning curve.

Strong operational forecasting capabilities: The platform continuously updates projections over time, allowing lease expirations, vacancies, financing events, and reserve requirements to impact forecasts dynamically. Solsten also blends actual operating history with assumptions through machine learning–enhanced forecasting to improve long-term projection accuracy.

Integrated portfolio and investor management: Solsten allows firms to aggregate assets into portfolios and provide investors with role-based access to dashboards, ownership information, distributions, and performance reporting. Sponsors maintain granular control over visibility and permissions while avoiding the need for separate investor management software.

More affordable than legacy platforms: Compared to many institutional CRE analysis tools that charge thousands of dollars annually per seat, Solsten offers significantly lower pricing while still providing advanced underwriting and operational modeling functionality.

Cons Explained

Does not currently support hospitality or self-storage: Solsten does not currently support hospitality or self-storage properties, which may limit adoption among firms specializing in those sectors.

Early-stage, rapidly evolving platform: As a newer entrant, Solsten is still building its user base and expanding its feature coverage. Some advanced capabilities found in mature enterprise platforms — such as hospitality and self-storage modeling and a public API — remain on the roadmap. The platform is backed by an extensive automated test suite and a deterministic calculation engine designed to prevent regressions, and new functionality is released on a rapid cadence.

Key Features

Full-Stack Proforma Modeling

Solsten generates institutional-style annual and monthly operating statements covering the full pipeline from PGI and EGI through NOI, debt service, and cash flow. Users can drill into line items, compare going-forward versus since-acquisition returns, and model exit scenarios across multiple hold periods.

The platform also incorporates contract-rate vacancy methodologies that dynamically adjust forecasting assumptions as leases expire and rollover scenarios evolve. Built-in exit scenario analysis models IRR, NPV, and equity multiples by year, helping users evaluate potential disposition timing and long-term investment performance.

Three-Column Operating Statement (Actuals + Projections)

Solsten generates a three-column operating statement showing Actual Year-to-Date, Projected Remaining, and Full-Year Forecast side-by-side. As actual operating data is recorded, projections automatically blend with reality — eliminating the need to maintain separate “actual” and “budget” workbooks. This format is uncommon outside of ARGUS and is particularly valuable for asset managers tracking variance, lenders monitoring covenant compliance, and LPs reviewing performance against pro forma.

End-to-End Property Lifecycle Management

Unlike traditional underwriting software that primarily focuses on acquisitions, Solsten is designed to remain active throughout the full investment lifecycle. Users can analyze a property, transition to active ownership, and continue managing leasing, financing, forecasting, and investor reporting on the same platform.

Tenant and Lease Lifecycle Modeling

The platform includes detailed lease management tools covering lease terms, rent escalations, renewals, holdovers, subleases, rent abatements, security deposits, tenant improvements, and vacancy assumptions. Weighted renewal probability modeling allows users to forecast multiple occupancy outcomes more realistically than traditional static underwriting models.

Recoveries and Expense Modeling

Solsten supports NNN, base year, and modified gross recovery structures with automatic expense linking and institutional-grade recovery methodologies. Users can model unlimited expense categories with custom frequencies, fixed versus variable allocations, and import directly from T-12 operating statements through a smart auto-detection wizard.

Financing and Waterfall Analysis

The platform includes advanced financing tools that support fixed, floating, hybrid, and construction loans, as well as amortization schedules, DSCR covenants, refinancing assumptions, and prepayment penalties. Solsten also supports institutional-style waterfall structures with GP/LP splits, preferred returns, catch-up provisions, and reserve forecasting.

Lender View & Covenant Tracking

Solsten provides a dedicated lender-facing view with actual DSCR, LTV, debt yield, and per-loan covenant compliance tracking computed against operating actuals rather than original underwriting. This is useful for refinancing conversations, quarterly bank reporting, and identifying covenant pressure before it becomes a problem.

Deterministic Financial Engine

One of Solsten’s biggest differentiators is its deterministic financial architecture. Rather than relying on AI-generated projections, the platform uses centralized rules-based calculation systems across forecasting, occupancy modeling, inflation assumptions, waterfall distributions, and return calculations. This helps improve consistency, transparency, and auditability.

Machine Learning Forecasting

While calculations remain deterministic, Solsten selectively uses machine learning to improve forecasting accuracy over time. As actual operating data is entered, the system begins to identify historical trends in inflation, occupancy, expenses, and revenue performance, blending real-world property behavior with user assumptions. Solsten’s “fluid timeline engine” automatically adjusts projections as time passes, allowing vacancies, lease expirations, rollover assumptions, and financing events to dynamically update without requiring users to rebuild models manually. 

15-Factor Risk Scoring

The platform automatically evaluates properties using 15 weighted risk indicators, including WALT, tenant concentration, DSCR, LTV, break-even occupancy, debt maturity exposure, and vacancy risk. These metrics feed into a centralized risk scoring dashboard designed around a “what breaks first” philosophy — surfacing vacancy drift, expense creep, and exit cap compression before they erode returns. Combined with year-by-year exit scenario analysis, the system helps operators stress-test assumptions before acquisition or refinancing decisions are finalized.

Saga AI Assistant

Saga is Solsten’s AI-powered assistant designed to accelerate onboarding and improve usability. Users can generate example properties, ask natural-language questions about assumptions or return drivers, and receive grounded responses tied directly to their models and property data.

Portfolio and Investor Management

Solsten includes integrated portfolio and investor management tools that allow firms to aggregate property performance, ownership structures, and distributions into a single environment. LP investors access dedicated dashboards showing only their own ownership percentages, contribution history, distributions, and investment performance — privacy is enforced at the data layer, so LPs never see other investor names, capital amounts, GP fees, or waterfall tier structures. Sponsors maintain granular control over disclosure levels and visibility, eliminating the need for separate investor portal software.

Excel Import and Data Validation

To reduce setup time, Solsten includes import tools that map tenant and expense data directly from spreadsheets, with smart auto-detection for T-12 operating statements and rent rolls — including Excel files exported from ARGUS Enterprise. The system automatically validates data, flags inconsistencies, and checks occupancy totals before information is added into the model.

Collaboration, Sharing, and Auditability

Solsten allows teams to manage permissions at both the organization and property levels while securely sharing models with investors, lenders, brokers, and analysts. External users can view properties in read-only mode or clone models into their own workspace without impacting the original file. The platform also maintains searchable audit logs, version history, and historical states for improved transparency and governance.

User Experience

Solsten follows a structured, step-by-step workflow similar to tax preparation software, guiding users through property setup and ensuring required inputs are completed before advancing.

The interface includes tooltips, validation checks, and real-time feedback, making it accessible even for users transitioning from spreadsheets. AI-assisted onboarding further reduces friction for new users.

Compared to traditional enterprise underwriting software, Solsten feels significantly more modern and approachable while still offering institutional-level analytical depth.

Customer Support

Currently, customer support is highly personalized, with direct access to the founder for troubleshooting and feedback. The built-in AI assistant (“Saga”) also provides real-time guidance on both platform usage and financial logic.

As the platform scales, support is expected to expand to include dedicated teams and more formalized resources.

Pricing

Solsten offers four pricing tiers designed to scale from individual investors to institutional teams. Plans range from a free entry-level option to custom enterprise pricing, with paid plans starting at $99/month, based on property count, analysis volume, collaboration needs, and portfolio management functionality.

The Professional tier, geared toward active firms and brokerages, costs $179/month on monthly billing or $161/month when billed annually, and includes advanced capabilities like unlimited analyses and waterfall modeling. The Starter tier is $99/month monthly or $89/month annually. Enterprise pricing is tailored for larger organizations that require API access, custom branding, and dedicated support.

Compared to legacy CRE analysis platforms that can cost several thousand dollars per seat annually, Solsten positions itself as a more affordable institutional-grade alternative for owner-operators and growing investment firms.
