The cost when buying a Timeshare is as follows: first, the owners pay for their unit. When sold by developers, financing is available for first time buyers but most re-sales are paid for in cash. Secondly, all Timeshare holders share maintenance fees, management fees and costs of upkeep. This includes areas like pools, tennis courts and etcetera. Keep in mind fees differ so be sure to have them disclosed to you before you buy!
