About

Rent vs Buy is a home-decision explorer: it runs hundreds of Monte Carlo simulations on real market data to show not just whether to buy, but when, where, and how the choice plays out over time. Every scenario accounts for mortgage amortization, PMI, property taxes, maintenance, tax deductions, investment returns, and home appreciation — all with realistic variance from historical data. No two runs are identical because markets aren't.
