The prompt

Build an interactive single-page land deal calculator Artifact. I flip vacant land and sometimes sell with owner financing.

Inputs (editable, with sensible defaults I can change):
- Estimated market value (from my comps)
- My target offer % of market value (default 25-35% for rural land; let me set it)
- Closing costs, title, doc prep, recording (flat $ or %)
- Back taxes / liens, survey, marketing, holding cost per month and months held
- Exit A, cash sale: sale price, agent/marketing fees
- Exit B, seller finance: sale price, down payment, interest rate, term in months, servicing fee per month

Outputs:
1. Max offer price to hit my target profit [e.g. $10,000] or ROI [e.g. 100%] on cash exit.
2. Cash exit: net profit, ROI, annualized ROI given months held.
3. Seller-finance exit: monthly payment, total collected, profit, months to recoup my cash, and IRR estimate. Show the amortization table in a collapsible section.
4. A green/yellow/red flag based on my thresholds.
5. A "save deal" list so I can compare several parcels side by side, plus CSV export.

Show formulas or a "how this is calculated" note under each output. Label everything as an estimate, not financial advice.

Paste the prompt into Muse and set your default thresholds once.
For each new lead, enter comps-based market value and the costs you know.
Ask Muse to compare saved deals: 'which of these three should I offer on first and why?'
Verify numbers with your title company and CPA before closing.
