Not at all.
With a co-owned home, you own a portion of the home (not only the right to use time there). You actually own a share of the home’s equity, and you can benefit from any appreciation in the value of the underlying real estate over time. By contrast, with a timeshare, you own only the right to use the property, typically for a fixed period of time each year.
If you want to sell a timeshare, you must attempt to sell it back to the resort operator who sold it to you, which often results in a loss relative to your purchase price. In general, with a co-owned home, you simply need to list your share on the provider’s marketplace to find another buyer.
Timeshare properties are typically hotel rooms or condo units in a resort property, while co-ownership properties are standalone vacation homes in prime locations chosen for their physical beauty, cultural heritage, and access to multiple outdoor activities.
