About the BRRRR Portfolio Simulator
Model acquiring properties each year via BRRRR and watch your doors and monthly cash flow compound.
It's built for directional planning: change any assumption and watch the whole projection move, the way a seasoned operator pressure-tests a plan before committing capital. Everything is computed live in your browser — nothing is sent anywhere.
How the BRRRR Portfolio Simulator Works
The model takes 3 assumptions and returns 3 headline metrics plus a full breakdown. Here is exactly what goes in and what comes out — no black box.
The Inputs
| Assumption | Example value |
|---|---|
| Deals per year | 3 |
| Cash flow / door / month | $300 |
| Years | 5 |

The Operator's Read
BRRRR's magic is recycling the same capital deal after deal — so the portfolio compounds without new savings. The real constraints are deal flow and financing, not cash.
Assumptions & Limitations
- •The model is deterministic: it projects your inputs forward with clear arithmetic, not a Monte-Carlo or probabilistic forecast. It shows one scenario at a time — run several to bracket a range.
- •Defaults are illustrative benchmarks, not your business. Replace every field with your real numbers before drawing conclusions.
- •It abstracts away taxes, financing, seasonality, and one-off events unless a field explicitly captures them. Treat the output as a directional estimate.
- •This is an educational tool, not financial, investment, tax, or legal advice. Validate real decisions with a qualified professional.
