Useful without pretending to know everything.
DealYield provides educational pre-tax estimates. It does not verify a property, approve a loan, or recommend an investment.
How DealYield approaches analysisExplain the math
Formula references sit near the results so each output can be reviewed instead of accepted as a black-box score.
Keep caveats visible
Warnings and educational boundaries are part of the workflow, not hidden behind a registration or payment step.
Protect the core workflow
Calculator updates happen locally, and optional services must never control or rewrite the financial calculation.
