• Judging vehicle condition and value
• Negotiating at auctions and with buyers
• Careful with title and sales paperwork

• Most states require a dealer license once you sell more than a few vehicles a year, and selling without one can bring fines, so check your state's rules
• Dealer licenses often come with a surety bond, garage liability insurance and a physical business address, so check whether a home address is allowed
• Hidden mechanical problems and title issues such as liens or odometer problems; check each vehicle history report
• Check which federal and state used vehicle disclosure rules apply, such as the FTC Buyers Guide, and how sales tax is handled in your state
• Cash is tied up in inventory, so a vehicle that does not sell can strain your finances

Monthly revenue is typically estimated at around $10,000 to $50,000, depending on how many vehicles you sell and their prices. That is revenue, not take-home pay, since purchase, repair and fee costs come out of it.

Check your state's dealer license rules, since selling more than a few vehicles a year may require one. Also check surety bond, garage liability insurance and business address requirements, vehicle history and title issues, FTC Buyers Guide rules, and state sales tax handling.
