Richard Sandomir and Ken Belson of the New York Times, the Wilpons and Mets team president Saul Katz are willing to sell more than 20 to 25 percent of the team as long as they hold the majority.
"Let's just say that a noncontrolling stake could be north of 25 percent," said Steve Greenberg, who is advising the Mets on the sale.
Time for a process of sale like this (according to the NY Times) can take awhile. Bidders have to get a background check from Major League Baseball, which includes their Financial records so they can prove they can back their financial investment.
The Times is claiming that the portion (25%) which the Mets are looking for can run about $100 Million.
Then once the bidder is approved by all owners and MLB the bidder can examine all the Mets Financial Books. Bidders can adjust their expectations on what to offer for a piece of the club, or walk away.
