Such properties are usually in the form of resorts/condominiums/vacation homes, where multiple owners share the rights to use a particular property at different times (pre-decided or allotted) of a year. There are basically four types of timeshares:
 Fixed Week
In this format, a sharer usually owns the right to the property/unit only during a particular week each year, for the entire duration of the contract. This option has very little scope for flexibility. With this type of timeshare, the owner can rent out his/her share or exchange with owners of a different property, which is normally feasible only if the location of the said property is in high demand.
 Floating share
This type offers the owner the right to reserve his/her share for a given period of the year. It has more flexibility than the Fixed Week system, but is prone to possible date clashes with other owners, especially during the peak seasons.
 Right-to-Use
In this arrangement, the owner leases the property/share for a given amount of time each year for a fixed number of years. In this manner, the sharers maintain the ownership rights, and yet earns some revenue from leasing.
 Points Club
This is like the to the floating timeshare, but owners have the right to stay at various locales depending on the number of points accumulated from buying into a particular property or purchasing points from the club. Points, here, are used like currency, and time-slots are reserved on a first-come basis.

Although the prospect buy used timeshare property for $1 is tempting, it is not a fruitful investment, since a potential buyer has to pay much more in the end. The main reasons for this deduction are as follows:
 High maintenance fees
Buying a timeshare does not just mean purchasing a certain amount of time at a particular property. The catch is the compulsion of paying extra fees for upkeep of the same, which are usually quite high.
 Long-term commitment
Timeshares are long-term affairs, and quite expensive too. In order to get rid of this obligation, owners, apart from selling their properties at trivial amounts, offer to pay for all the contract closing and transfer costs eagerly.
 Lack of control
An investment is not a good one if the real decisions are taken by a third party. Same is the case with timeshares.
 Low resale value
Given the drawbacks of the concept, resale of timeshare properties is not a rosy affair.Go here : https://www.timeshareforadollar.com/
