Global real estate is collectively worth 170 trillion dollars. That number makes property more valuable than any other asset class.

What makes the real estate market so pricey? In part, massively expensive houses that rich and famous people own, many of which cost more than 100 million dollars by themselves.

If you can’t wrap your head around the idea that houses are worth that much money then you haven’t seen the most expensive houses in the world. Below, we share with you five of the most noteworthy, almost all privately owned estates on the planet.

1. Oprah Winfrey’s Promised Land

We all know Oprah from her world-famous talk show that she hosted until about a decade ago. What you may not know about the famous television star is that she’s worth about 3 billion dollars.

As it turns out, Oprah used a small chunk of that money to construct her almost 100 million dollar mansion, Promised Land, in Montecito, California.

Promised Land features 14 bathrooms, 10 fireplaces, and several other jaw-dropping amenities.

2. Daren Metopuplos’s Playboy Mansion

You can’t talk about the most expensive houses in the world without mentioning the historic, Playboy Mansion. The mansion used to belong to Hugh Hefner who passed away in 2017. Before he died, Hugh sold the house for between 100 and 200 million dollars to Daren Metopuplos.

The house boasts 12 bedrooms, a zoo-license and sits on 5 acres of land.

3. Buckingham Palace

Buckingham Palace is often cited as being the most expensive house in the world. While the house hasn’t hit the open market which makes it impossible to know its true value, real estate experts put that mansion at about 2.2 billion GBP.

That high valuation comes thanks to Buckingham’s 755 rooms and rich history.

This house is owned by a trust, not the queen herself.

4. Bruce Makowsky’s 8th Wonder of the World

If you can’t afford to hop on to see new wonders of the world like Vietnam’s Ha Long Bay, you can head over to Bel-Air to check out a home that has been dubbed the “8th Wonder of the World”.

Real estate developer Bruce Makowsky’s almost 40,000-square-foot mansion comes complete with an infinity pool and a helicopter landing pad. It was the most expensive home in the US when it hit the market in 2017 for 250 million dollars.

5. Hearst Castle

For you cinema fans out there, Hearst Castle was built by Randolph Hearst who inspired the film, Citizen Kane. Mr. Hearst worked on his mansion’s construction until the day that he had to leave due to his health.

The house remains unfinished, per Hearst’s original specifications. Hearst Castle belongs to Heart Corp. today and features 165 rooms.
