The resale value of a timeshare is typically much lower than the initial purchase price, and finding a buyer can be extremely difficult.
Some timeshare contracts are automatically transferred to next-of-kin upon the owner's death. Families often have to file a "disclaimer of interest" within a specific time limit to avoid inheriting these obligations.
You have a contractual right to use the property for a set number of years, but the developer retains ownership.
