An 86-acre island with a six-bedroom, nearly 12,000 square foot home in Maine is currently on the market, according to ABC News.

But hey, these other pads aren't too shabby either.

From the days when Cornelius Vanderbilt built The Breakers in Newport, Rhode Island to Donald Trump's conversion of Mar-a-Lago into a private residence for his family, Americans have been obsessed with mansions.

The housing market has continued to rebound significantly throughout the country, especially benefiting the high-end, as stock markets hit record highs. In an April 2017 Redfin report, home sales rose 9% year-over-year as of March 2017. The average price continued to rise, up 7.5% year-over-year to $273,000. This comes as more people are looking for homes, be it first-time buyers or families looking to move into larger dwellings.

Even though the American dream has come roaring back, $273,000 is still a far cry from the multi-million dollar mansions spread out across the country.

From California to New York to Texas, some of the country's most expensive homes for sale scream opulence and decadence. Courtesy of real-estate listing service Trulia, TheStreet has compiled a list of the 15 most expensive across the country.
