How to use home decisions tools
Begin with the tool that matches the decision in front of you and enter figures you can verify. Test a realistic case, a conservative case, and the point where your preferred option stops working. That range is usually more useful than a single optimistic result.
Review the assumptions behind each result—especially time horizon, taxes, recurring costs, financing, and opportunity cost. The tools in this housing collection are designed to expose those tradeoffs so you can compare choices consistently, not to predict an exact outcome.
