It started with the Mayan properties, and has now spread to the timeshare properties owned by the Bulnes family - Solmar, Grand Solmar, and Playa Grande.
Without any notice, the Bulnes family raised the "Resort Transfer Fee" for their properties to be 10% of the original sales price (NOT the price you may have paid for your week/unit). If you use a broker or other third party to sell your timeshare, then they will pay 40% of the original sales price in the form of a "Resort Transfer Fee".
What does this mean? Let's say last year you purchased a Playa Grande timeshare week on eBay for $2,000. This week originally sold (back in the day!) for $30,000. If you decide to sell your unit, you will have to pay to Playa Grande a $3,000 "Resort Transfer Fee". That is $1,000 more than what you paid for the week in the first place!
If you use a broker to sell your week, the "Resort Transfer Fee" jumps to $12,000!
The Bulnes owned resorts do not have any type of resale program for owners, so owners have no choice but to sell their units themselves if they no longer want them. Now, you are effectively prevented from selling your unit, unless you want to take a huge loss (even greater than the normal loss you'd take when selling a timeshare unit).
If you already own at a Bulnes resort, please feel free to contact them and voice your displeasure. Fair warning, they do not care and if you make your complaint publicly, such as on their Facebook page, they'll respond that they'll "contact you shortly" but then will hide your post from their timeline so that no one else can see it. Then it will eventually be deleted a few days later.
If you do not own at the Mayan or at a Bulnes property, but you do own a Mexican timeshare, you'd better go check your contract to see if Resort Transfer Fees are listed in your contract. If not, then your resort can choose to raise the fee anytime they want, without consequence. And, no doubt, once this catches on, your resort will eventually follow suit as well.
As an owner of four timeshare units that are now essentially worthless and cannot be resold, please heed my warning. It could happen to you.
And if you do not already own a Mexican timeshare, please consider yourself warned! The Resort Transfer Fee at the time I purchased my units was $100. Now it is thousands and thousands of dollars! I'm stuck, but it's not too late for you.
