An offer is not a percentage pulled from the air. It begins with realistic resale—not an optimistic asking price—then accounts for fees, testing, time, inventory risk, and the margin required to stay in business.

- Use comparable sold results, not active listings.
- Subtract marketplace and transaction costs.
- Account for time, grading risk, returns, and slow inventory.
- Put the number and assumptions in writing.
