Inside Four Mansions With Underground Secrets

[magno]

Got to say, that Swiss mansion really reflects that the architect had a great eye for design. Hands down, blew the other mansions away.

[Ralph-cxgk]

Honestly that first home in Switzerland should of been #1

[c.]

Imagine quarantining in one of these houses

[dreplays]

First home is my dream home, I’d never leave lol

[rrdigital]

Asked for 53 million got 22 million geez !!!

[capncris]

Imagine trying to find your 3 year old son in those mansions.

[Clamburglars]

"Pool the size of a lake". Smallest lake I've ever seen

[supersquare]

I would 100% get murdered on the staircase of the first home

[FlipsterFlipinoy]

Hacienda de la Paz listed for $53M, sold at auction for $22.4M. BARGAIN BASEMENT!

[alys]

Yikes!! The third house sold for just over the cost of the tennis court alone. They took a massive hit on that house😬

[siriosstar]

So if these homes are dream homes for the owners, then why did they sell them ?
Did the upkeep become a nightmare ?

[sharksport]

I'm definitely painting the front door of my trailer gold now.

[BeingSardar]

I would feel scared in such a big house...

[sugamoppie]

As a Moroccan I'm jealous of the second home's hammam it's freaking gorgeous!

[BadDollsTV]

can you imagine how much the electricity bill is for these “houses”? sheesh.

[TheDanielleDenise]

I think its pretty smart to optimize your space by building underground.

[MiniM]

If a property is sold at auction, doesn’t that mean it was a foreclosure? That place was basically a bargain!

[cervacio]

"former fitness model, one time Patron girl" 😂😂nuff said.

[afterthestorm]

Beautiful spaces for sure, but to me I would never feel quite at home being so spread out from one another. 💚

[Henry-snjs]

“360 Degree, See Through Shower, hope you’re not shy!”

You didn’t have to do me like that
