15 extravagant vacation homes you can rent with the Airbnb for billionaires

Buying a second home is a big commitment. But what if that investment granted you access to an exclusive club with luxury properties around the world? You might never have to pay for a hotel again.

That's the idea behind 3RD HOME, a "reciprocal travel club" or "AirBnB for millionaires and billionaires," as Forbes aptly put it.

The concept is simple: list your property (of $500,000 value or more), pay a $2,500 initiation fee, and feel free to book vacations to any of the more than 4,800 estates around the world currently in the 3RD HOME portfolio. A selection of high-end partner resorts, including the Ritz-Carlton Destination Club, are also part of the membership.

"What people like is that the quality level is above most rental sites," Steve Zacks, chief marketing officer for 3RD HOME, said to Business Insider.

Here's a teaser of just a few of the gorgeous properties 3RD CLUB members have access to.
