Methodology & next steps

This tool runs entirely in your browser. Change one input at a time, compare scenarios, and export the report before you talk to an agent or lender.

  1. Start with realistic income, price, rate, and cost assumptions for your market.
  2. Use presets or Snapshot as B to stress-test a second path.
  3. Read the verdict, charts, and schedule — then verify taxes, insurance, and comps locally.
