It might not be such a wise investment 80 years from now.
Trump has not one, but two addresses at Pennsylvania Avenue. In addition to his residence at the White House, he owns the opulent Trump International Hotel down the street.
In August, the Washington Post reported that the new hotel turned a $1.97 million profit so far in 2017. It charges an average of $652 a night — more than most hotels in the nation's capital.
Because the Hollywood Beach, Florida, property sits between the Atlantic Ocean and a waterway, it could be inundated with floodwaters from both sides due to sea-level rise.
The newest oceanfront condominium in the president's real-estate portfolio is Trump Hollywood, a 41-story glass tower that contains 200 units, all with private elevator access.

Trump owns part of 555 California Street, a brown behemoth located in the city's Financial District. It's often referred to by its former name, the Bank of America Center.
Trump has few supporters in San Francisco and even fewer real-estate properties.
It currently sits vacant. In 2100, it could see massive amounts of flooding.
New Yorkers have a range of gambling options within a three-hour's drive of the city. Trump Plaza in Jersey City was one of the closest casinos, until it shuttered in 2014.

Located just up the beach, Trump Grande consists of a beach resort and two residential buildings. The hotel is known for its sprawling lagoon pool and man-made waterfalls.
By the year 2100, an oceanfront view might not be such a luxury.
The Trump Towers are three nearly identical pillars located on the edge of the quaint seaside community of Sunny Isles Beach, Florida. They contain 813 luxury condo units.
Extreme sea level rise could devastate Wall Street. It might reach the tower's doorstep.

The good news for Trump, who owns about a dozen properties in the city, is that most of his hotels and residences sit inland where the effects of sea-level rise are usually less catastrophic.
New York City is situated on one of the world's largest natural harbors, which makes it more vulnerable to sea-level rise. The Hudson River could flood the city's low-lying areas.
But Trump will be out of office by the time anything like that happens.
If sea levels rose by as much as 12 feet, the Mar-a-Lago estate would not fare well.

Trump has spent more than a quarter of his presidency in Palm Beach, Florida.
The new owners have plans to reopen the Taj Mahal in 2018, but polar melting, carbon emissions, and ice-sheet could cause flooding to destroy the tower within the century.
Trump built the Taj Mahal casino for $1.2 billion in 1990. It overlooks the beaches of Atlantic City, New Jersey, and has been described by Trump as the "eighth wonder of the world."
In a worst case scenario, flooding caused by polar melting and ice-sheet collapses could cause a sea level rise of 10 to 12 feet by 2100, NOAA reported in January.
