While you may never be able to purchase your own luxury home, according to an article in The Wall Street Journal, people can still have the perks of owning a big home by becoming fractional owners.  

Fractional real-estate ownership differs somewhat from timeshares. It typically applies to high-end properties, and ownership is split among fewer people. Periods of annual usage are typically three to four weeks rather than one to two, and privileges may extend to more than one luxury property. Another draw is concierge-level services that a guest would receive at a luxury hotel.

Fractional owners are able to sell their stake, leave it in a will or put it in a trust, the article explained. However, the deal does come with some negatives, like limited ability to make changes to the property.
