Timeshare cons are among the most frequently complained about scams in the United States.

Typically, timeshare owners receive unexpected phone calls from con artists, posing as timeshare sales representatives. The scammers claim that they can sell the property within 60-90 days. They pair their offers with high-pressure sales maneuvers, adding urgency to the deal.

Once the timeshare owners have agreed, they’re charged with an upfront fee to cover up ad costs. With the promised sale, most timeshare owners surrender their credit card information. And once the funds have cleared, the scammers disappear without a trace.

In select cases, victims of the scam consult timeshare fraud recovery companies—which, from time to time, are scammers too.

The best approach when dealing with resale companies is to check the business name with the Better Business Bureau.
