Most expensive house (we could get into): Battery Park, NYC

They're calling it "The Penthouse Collection." We call it, New York City's mansion in the sky.

This listing is a once-in-a-lifetime opportunity to combine not one penthouse, but three! Yep, you read that right: The combination of these units would take up the entire top two floors of the Residences at the Ritz Carlton in NYC's Battery Park City.

The owners of three contiguous apartments are simultaneously putting their units on the market.

The asking price? It can be yours for $118.5 million.

The potential duplex penthouse has stunning 360-degree views from its four terraces, which offer a total of 2,200 square feet of outdoor space. A potential resident can wave to Lady Liberty or soak in the views of One World Trade Center from the outdoor hot tub.

If combined, the trophy penthouse would have more than 12 bedrooms, 15 or more bathrooms and at least three kitchens. With a grand total of 17,634 square feet of space, the buyer also gets the bragging rights of owning one of the largest single-family residences in Manhattan.
