Rent-vs-buy financial calculator for Chicago real estate decisions
A Python-based tool that compares buying versus renting in Chicago by modeling all real costs including mortgage, HOA, taxes, insurance, and opportunity costs. It provides tornado charts, breakeven solvers, and Monte Carlo simulations for uncertainty analysis. The project has a clean modular structure with core math functions, Jupyter notebooks for analysis, YAML-based property and scenario configurations, and a pytest test suite.
