Since the high season may extend from December through March, this offers the owner a little bit of holiday versatility. What kind of property interest you'll own if you buy a timeshare depends upon the type of timeshare purchased. Timeshares are generally structured either as shared deeded ownership or shared leased ownership. With shared deeded ownership, each owner is granted a portion of the real estate itself, correlating to the amount of time acquired. The owner receives a deed for his or her percentage of the system, specifying when the owner can use the property. This means that with deeded ownership, lots of deeds are issued for each property.
