You didn’t really use your timeshare you bought four years ago and are looking to sell it. You post it online and one day, you receive a call or email from a company that deals with timeshares. They say they have a client for you.
Happy to get rid of your timeshare, you agree to their terms - including a processing fee or a title search fee (both usually a few hundred dollars each). They will tell you the paperwork will be done in 14 to 20 days. When you call back after this period you will get a “number not in service” notification.
How to avoid: don’t fall for the official-looking name and logo of the company the scammers use. As realistic as the paperwork might look, always check online their reputation and past clients.
