Which tool should I start with?

Comparing a loan? Start with monthly payments and the maturity balance. Evaluating a rental? Test annual operations and refinancing cash separately. Planning work? Budget the construction scope and time spent holding the property.

The examples are hypothetical. Use current quotes and transaction documents for your inputs, and avoid counting taxes, insurance or loan payments twice when moving between tools.
