Since the high season might stretch from December through March, this gives the owner a bit of trip flexibility. What kind of residential or commercial property interest you'll own if you purchase a timeshare depends upon the kind of timeshare bought. Timeshares are generally structured either as shared deeded ownership or shared rented ownership. With shared deeded ownership, each owner is approved a portion of the genuine residential or commercial property itself, correlating to the amount of time acquired. The owner gets a deed for his or her percentage of the unit, defining when the owner can use the home. This means that with deeded ownership, lots of deeds are issued for each residential or commercial property.
