While Donald Trump is busy running the United States of America, his children, Donald Jr., Eric and Ivanka Trump will be busy running his billion dollar business. Although Trump-branded properties faced a decline following Trump’s decision to run for president, the real estate mogul’s properties have apparently shifted upward since he won the 2016 presidential election.

Some of Trump’s properties, like Trump International Hotel and Tower in Chicago, saw increases between 25 and 75 percent in value since he became the president-elect, Fox Business reported. Chezi Rafaeli, who has sold over 200 apartments in Trump’s Chicago location, said the Trump Tower in New York City went up almost 200 percent in value. The Coldwell Banker Residential Brokerage realtor said he had been receiving calls from people in Russia, Asia and Brazil looking to invest in Trump properties throughout the states.

“The property, in my opinion, will go up tremendously, especially if he does well in office,” Rafaeli said.

Trump has been adamant about his plans to turn over the Trump Organization to his oldest children. A Trump Organization spokesperson recently told CNNMoney that the company is already “vetting various structures with the goal of immediate transfer of management” to the oldest Trump children.

Trump has refused to put the company in a blind trust and hand it over to an independent trustee. He said during an interview with “60 Minutes” Sunday he has no interest in what happens to The Trump Organization and that his main focus was on saving the U.S.

“I don’t care about hotel occupancy. It’s peanuts compared to what we’re doing,” Trump said.

Trump's business holdings took a hit during the presidential campaign after he made controversial remarks about Mexicans, immigrants and Muslims. Macy’s stopped selling Trump brand merchandise, and NBCUniversal, Univision, Nascar and Serta mattresses called off business deals with him.
