How Opportunity Cost Works

When you buy, your down payment and closing costs are locked into non-liquid home equity, and you pay mortgage interest, property tax, maintenance, and insurance. When you rent, you invest that down payment upfront in index funds and invest any monthly savings difference.

Break-even logic: Buying typically lags in early years due to closing costs and upfront interest, but gains advantage later as loan amortization accelerates and rent compounds.
