The Office of Government Ethics released Donald Trump’s 2019 financial disclosure form this week.

These forms reveal much about Trump’s finances — including the reimbursement of the hush money his lawyer Michael Cohen paid the adult-film actress Stormy Daniels — but the form also provides insight into first lady Melania Trump’s income.

Two of her disclosures were related to a one-bed, 1.5-bath apartment in Trump Tower in Manhattan that Melania bought from the building’s condo board for almost $1.5 million in January 2016, according to The Real Deal.

Melania Trump owns apartment H on the 33rd floor. There aren’t any photos of that unit available online, but these photos from StreetEasy show apartment 32H, which looks to have the same layout.

Her apartment is 1,052 square feet and located on the southeast corner of the building, overlooking Fifth Avenue and East 56th Street.

It has one bedroom, also with sweeping views. Trump’s disclosure form lists “721 33H LLC,” the apartment’s address and a pass-through company for the property, saying the real estate is valued between $1,000,001 and $5 million.

In January 2016, Melania bought the unit for $1.49 million, apparently from the building’s condo board. It appears to be the only one the board has ever bought, The Real Deal reported, citing property records.

This type of unit (a studio or one-bedroom in a luxury skyscraper) is usually used for staff members of residents who have much larger apartments in the building, or for a live-in superintendent. The condo board first bought unit 33H for $650,000 in 1997.

While it’s unclear why the first lady bought this apartment, some speculate it was for use as a library.

Or maybe it’s just a private space for her to get away from it all and relax. Since she has never mentioned the apartment, it’s a mystery.
