President Trump’s net worth fell to $2.9 billion from $3 billion over the last year, according to a report.

Trump’s $100 million doozy is getting blamed on a trio of Manhattan skyscrapers that aren’t generating as much cash as Trump’s lenders for the properties expected.

Trump Tower, as well as the president’s buildings at 40 Wall Street and 1290 Avenue of the Americas, have seen their value cut by a combined $380 million, Bloomberg reported Wednesday.

Those hits more than offset gains Trump’s other properties, including Mar-a-Lago, which saw a 25 percent jump in sales during the past year.

The dud buildings “are victims of a changing New York office market, where gleaming new skyscrapers are attracting tenants and demand for space in vintage properties is falling,” according to Bloomberg.

Trump Tower was appraised at $480 million in 2012, but has been downgraded to $450 million after an increase in expenses damaged earnings, according to lender documents found by Bloomberg showed.

Trump Tower generated $14.1 million in profits last year, versus $20.4 million in 2012, according to the documents.

The tower at 1290 Avenue of the Americas was expected to net $97.7 million last year, but fell short, only netting $77.7 million and failing to meet lender expectations.

“We’re in the biggest development pipeline in Manhattan since the 1980s,” Keith DeCoster, director of real estate analytics at Savills Studley, told Bloomberg. “Older buildings — circa 1980s, 1990s — are having a tougher time competing.”

Trump’s total debt, meanwhile, has shrunk to $550 million, from $630 million last year.
