Underwrite your deal in one session, not three days.
Institutional-grade engine. One consistent dashboard - whether you're screening a $500K BRRRR, underwriting a $10M value-add multifamily, or modeling a $50M ground-up development.
Solo or team. The same institutional standard either way.

One session. Complete deal.
Step 1 - Import
Upload your Excel model, rent roll, or P&L. The AI maps it to platform fields - you review and confirm before saving. No silent assumptions.
Step 2 - Model and Test Alternatives
Switch asset classes, restructure financing, change waterfall structures, swap exit strategies - every option recomputes instantly. Test scenarios your Excel model can't even open without rebuilding from scratch.
Step 3 - Export and Share
Export a Project Summary PDF, a formula-linked Excel proforma your accountant can audit, or share a live link with role-based views - lenders see debt metrics, LPs see returns.
Built for every deal type
Ground-Up Developers
Phase-aware financing from land to stabilization
- Residual land value solver - find your maximum buy price at your target IRR
- Construction-to-permanent loan rollover with exact interest-carry calculations
- Pre-sale deposit offsets that reduce equity draw during the quiet period
Multi-Family and Commercial
Built for syndicators raising capital and operators scaling portfolios
- Bifurcated PropCo/OpCo waterfall with operating and capital event paths - model the structures real syndicators actually use
- Lease rollover with vacancy, concessions, and rent bumps across every unit
- Value-add renovation modeling - see exactly how CapEx lifts cap rate and exit value
BRRRR Investors
The only platform that models the full BRRRR chain
- Sequential refi chain - cash-out from each deal funds the next acquisition automatically
- Multiple refi events per property - rate-and-term plus future cash-out refis on the same deal
- Blended IRR across your entire chain - one number that captures the full recycling strategy
Analysts and Modeling Freelancers
Replace the spreadsheet you've been patching for years
- IRR solver with 200-iteration bisection at 1e-10 tolerance - no more #REF! or circular reference errors
- Multi-LP class waterfall with GP catch-up, IRR hurdles, and equity multiple gates
- Built-in auditor checks deals against your firm's investment thresholds before you present
The BRRRR chain. No one else has modeled this.
Most tools model one deal. OneStopReal models the entire capital recycling strategy.
Each refinance cash-out automatically flows to the next acquisition
Equity injections fill the gap when cash-out falls short
Blended IRR across the entire chain - one number that tells the full story
Weeks of revisions. Or one 2-hour meeting.
See how OneStopReal compresses the entire deal structuring cycle into a single live session.

Engine Integrity
200-iteration bisection IRR solver with 1e-10 tolerance. No circular references. No approximations. The same precision your investment committee or capital partner expects.
Test Coverage
200+ financial invariant test cases verify that equity splits match LTV, debt service matches the amortization schedule, growth rate overrides apply correctly to exit valuation, and the levered cash flow identity holds - automatically, on every calculation.
Two Layers of Audit
The calculation methodology is publicly documented - every assumption, every derivation, every edge case. Excel exports include clearly labeled schedules so every number is traceable back to its source. And the built-in Underwriting Auditor checks your deal against your firm's investment thresholds before you walk into the room.

Frequently Asked Questions
Can I import my existing Excel model?
Yes. Upload your model and the AI maps fields automatically. You review every mapped field before saving.
How accurate is the math?
Audit-grade. The engine is verified against 200+ financial invariant test cases. Our full calculation methodology is published openly.
Can I export to Excel for my client, lender, or CPA?
Yes. Every project exports to a clean Excel proforma and a bank-ready PDF lender package. Excel exports include clearly labeled schedules - every number is traceable to its source. Role-based sharing gives lenders debt metrics only, while investors see the full return picture.
What if I cancel my subscription?
Your projects remain accessible in read-only mode. Export to Excel before canceling to keep working copies.
Is there a free trial?
Yes. 14 days, no credit card required.
What's the difference between Pro and Team?
Pro supports one editor. Team supports up to six collaborators editing together. Both have the same calculation features.
Do you support international markets?
Yes - real estate models are typically built pre-tax, and the platform's flexible expense structure adapts to jurisdiction-specific costs like stamp duty, property tax, or council tax. Currently supports USD, EUR, GBP, ILS, AUD, AED, NZD, SGD, CAD, CHF, and INR, with additional currencies added on request.
