There’s a new twist on the old timeshare. It’s a start-up called Pacaso that takes the timeshare model and expands it to something closer to owning your own single-family vacation home. Instead of owning a second home and all the costs that go along with it, Pacaso finds co-owners to share the expense. Scheduling for use of the home is flexible, and allows for much greater access than a timeshare. And, Pacaso takes care of all the management.
