Not just news but important to know: Since 2014 the RDO (Resort development organisation) where Anfi Group is member, publishes the ‘Code of conduct for surrendering timeshare”:
“In the event of the death of a joint owner, the surviving owner can surrender their timeshare if they wish and additionally, the beneficiaries of a will are not obliged to take on the timeshare if they do not wish to do so
If a sole owner or either of the joint owners is suffering from a long-term illness that prevents them from travelling to their resort for the foreseeable future, the timeshare interest may be surrendered.”
This means you cannot leave the resort even if you are old but if a joint owner dies or one of the owner has health problems and cannot travel anymore the owner can leave the resort.
Nothing is said about what the resort pays back for the weeks. That may change from one resort to the other and is not published by Anfi. Normally you would expect that this is more than you get by a buy-back program.
