While viewers may not have thought that a real estate show could be engaging (or lucrative), 'Selling Sunset' proved that selling houses can definitely be sexy.

Of course, though many of the show's biggest attractions (like former Playmate Heather Rae Young or Sports Illustrated model Emma Hernan) are also the biggest points of contention. After all, critics have alleged that many of the show's agents are only on the series for ratings -- and aren't actually selling real estate.

And sure, Netflix doesn't show everything about 'Selling Sunset,' and what it's really like to work in real estate. But as it turns out, there is plenty of work going on in the Oppenheim twins' real estate office.

Still, just how lucrative is this industry, how much is the Oppenheim group worth, and how do they make their money?

Who Created 'Selling Sunset'?

Though the Oppenheim twins are the brokers and co-founders at the Oppenheim Group, the show was devised by Adam DiVello. Of course, that doesn't mean it's all fake; the real estate agents on the show do have their licenses.

And while the twins don't personally handle every real estate transaction, it is their legitimate business. The thing is, they seem to be so extremely wealthy even without the paychecks Netflix is cutting them. So what gives?

How Much Are Brett And Jason Oppenheim Worth?

Brett and Jason Oppenheim are reportedly worth about $50 million -- but sources seem to disagree on whether that's per twin, or a combined net worth. They're clearly the wealthiest of their team, either way, and many of the staff members have side gigs, say news sources.

As most fans of the show realize, real estate agents make their income based on commissions. So they earn a percentage of each sale, which can add up when they're selling luxury properties worth millions.

Still, it's not easy to build up $50M in net worth as a realtor. So how did the Oppenheim twins manage it before starting their Netflix series?

How Did The Oppenheim Twins Make So Much Money?

Though they're undoubtedly earning cash for appearing on 'Selling Sunset,' the Oppenheim brothers didn't make all their money selling property. In fact, real estate is each of their second careers.

Both Oppenheim brothers began their careers as lawyers, which explains where a lot of their cash came from. Thanks to their joint ventures as part of the Oppenheim group, Brett and Jason Oppenheim were able to stow away their cash and keep piling it up.

Their family business is real estate, so it makes sense that the brothers are good at what they do. But it definitely helped that they likely had a nest egg to start off with after working as lawyers for around four years. Neither is a bad gig, but there may just be more money in reality TV (and fame) than in the legal field.
