How to read this decision

House Hack Frame answers the question listings never do: a hard property decision framed with clear trade-offs. Rent from a spare unit or rooms against your mortgage — live-for-less math.

There is nothing to install and no account to create — enter numbers, run it, and adjust until the picture is clear.

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.
  • Copy report or Print / PDF for a shareable decision page.
  • Save scenarios on this device or copy the share link in the address bar.
  • Export CSV/JSON when you want numbers in a spreadsheet.
