A few thoughts...
My parents have two timeshares they purchased in Mexico....they are getting on in years and don't want them anymore. It seems that alot of the advice on here is in reference to timeshares in the states, but not those purchased in Mexico.
Any thoughts/suggestions for timeshares purchased in Mexico?
Mexican timeshare weeks are not "owned" real estate. Instead, there is likely a "right to use" contract (not a deed) which is likely of specific time duration. You'd be wise to
first learn what that expiration date is within the current contract, as that information
might influence someone's interest in taking over the contract(s).
You'd also be well advised to find out (directly from the facility) in advance if the facility charges a transfer fee to acknowledge a change in contract "owner". If there is a cost, you need to think about who is going to pay it (i.e., your parents or a prospective contract transfer recipient). Even if they give it away for free, if there is a transfer fee,
someone needs to pay that fee for the transfer to be acknowledged.
Also, acquire from the MX facility any forms which they might use and require for processing transfers.
My suggestion would be to offer the RTU contracts here in the Bargain Deals,
after you know the answers to the above details. The weeks likely have zero resale market value, but someone
might be interested in picking up the remainder of the contract, particularly if the remaining "shelf life" is relatively short...
Just my own thoughts and opinion, fwiw...
