Donald Trump sold a condominium at one of his Manhattan properties for almost $14.1 million -- about a sixth less than the price listed last month -- as luxury home prices in the borough slide.

The 4,192-square-foot (389 square-meter) apartment spanning the entire 27th floor of 502 Park Ave. has a private elevator, four bedrooms and six-and-a-half baths, according to property website StreetEasy. It was listed Dec. 1 for $16.8 million, the site shows. Trump sold a unit on the building’s 24th floor for $21 million in July.

Amanda Miller, a Trump Organization spokeswoman, confirmed that the sale occurred. The billionaire never lived in the condo, according to a Wall Street Journal report on the transaction Wednesday.

A Bloomberg analysis valued Trump’s net worth at $2.9 billion in July, including $200 million for condominium stock at 502 Park Ave. The analysis valued the 27th-floor apartment at $18 million, based on then-recent sales at the property.

Trump is a leading contender to become the Republican nominee in the race for the U.S. presidency. A Bloomberg Politics/Des Moines Register Iowa Poll released Wednesday shows Trump and U.S. Senator Ted Cruz locked in a tight race for first place in Iowa, the first state to cast votes in the election.
