This is an old scam that targets Mexican timeshare owners. The "company" is fake and run by criminals outside of the US. The cold call (red flag) and offer a huge price (red flag) for a timeshare that is worth little to nothing. After one is hooked thinking they are getting big bucks the "company" asks for made up fees or taxes that need to be wired to Mexico (red flag). Many, many people fall for this and are out thousands of dollars with no satisfaction that someone is going to jail. If you are still doubting if it is a scam just substitute your 1998 Hyundai for the timeshare.
(Phone rings) Owner: "Hello?"
Scammer: "Hi, I am calling from Property Scamming Company and have great news. I have someone that wants to buy your 1998 Hyundai for $35,000. I will have some official looking contract documents e-mailed to you. Don't worry, no upfront fee!
Contract e-mailed - owner signs it and returns it gleefully waiting for $35,000 to be sent to him for a 21 year old Hyundai. One week passes.
(Phone rings) Owner: Hello?"
Scammer: Good news, your $35,000 check had been approved to be released to you! However, Mexico requires a SAT tax for on the proceeds. It needs to be paid by you but you will be reimbursed by the buyer at closing. Please wire $4,000 to Mexico and then your check to be received will be $39,000.
Owner wires $4,000 to Mexico. A couple of days passes.
(Phone rings) Owner: "Hello?"
Scammer: "Hello, we are close! Unfortunately, because you are not a resident of Mexico we have been informed by our lawyers that there is a new non-citizen application fee that is required for any vehicle proceeds leaving the country of Mexico. Please wire us $5,000 to Mexico and we will pay this fee on your behalf. We have gotten the buyer to agree to reimburse all closing costs so your check to be received, already approved by our management, is now $44,000.
More requests for funds to be wired continues until the owner finally stops at which point the "company" disappears.
No one in the right mind would fall for this scam if they got the cold call about their car. However, too many timeshare owners don't have a clue that their timeshare is not worth anything remotely close to what is being offered by the scammers. Most Mexican timeshares are worthless on the resale market.
