If confirmed, Trump's cabinet will be the wealthiest ever, with a combined estimated net worth of $5.6 billion.

Christopher Ritzert of Sotheby's International Realty is helping four of Trump's cabinet appointees find new homes in Washington, D.C.

"We've seen many people come through Washington with money but never this many with this much," he told Inside Edition.

He's shown them all a $4 million apartment at the Ritz-Carlton residences. It has three bedrooms and six-and-a-half bathrooms.

He said it is eight blocks from the White House and "a lovely walk down Pennsylvania Avenue."'

The cabinet appointees are also looking in the Kalorama neighborhood, also known as "Embassy Row," and fast becoming "Billionaire's Row."
