Rent vs Buy Calculator

Model rent growth, a fixed-rate mortgage, owner costs (taxes, insurance, maintenance, HOA), and a simple sale at the end of your comparison window. Opportunity cost on the down payment and detailed tax treatment are not modeled, use this to stress-test assumptions, not as a purchase decision by itself.
