Washington -  U.S. President Donald Trump took out a new 30-year mortgage on a sprawling oceanfront house steps from his own Mar-a-Lago estate in Florida, and it is sitting empty on the rental market, according to financial disclosures made public on Thursday by the Office of Government Ethics.

The $18.5 million West Palm Beach mansion was purchased in May 2018 from one of Trump’s older sisters and was secured with an $11.2 million mortgage that has a 4.5% interest rate, Florida public records show.

Trump disclosed the loan as a liability in financial disclosure forms filed this week.

A real estate website lists the eight-bedroom house, which is near the Mar-a-Lago beachfront estate and private club in Palm Beach, as available for rent for about $81,000 a month.

The Palm Beach Daily News reported that the president’s two adult sons, Eric and Don Jr., who are running his business while he is in office, bought the more than 10,000-square-foot (930-square-meter) house last year from Maryanne Trump Barry, a former federal judge.

Beginning in 2023, the interest rate can be increased, but is capped at a 2-percentage-point increase a year, according to mortgage documents filed with the county.

The White House declined to comment on the filings.

The financial disclosures are mandated by law and offer a peek into the president’s sprawling finances.

Unlike all other modern presidents, Trump has refused to release his tax returns, which would offer a clearer picture of how much money he is bringing in. The disclosures give a glimpse of the number of properties he and his businesses own.

Last year in May, Trump’s disclosure form made public for the first time that he repaid more than $100,000 to former personal attorney Michael Cohen, who had paid hush money to porn star Stormy Daniels about an affair she alleges to have had years before with the president. Read more at Reuters
