Nope. If one cannot afford to buy the other one out, and one brother wants out from under the ownership, the brother that wants out can solicit the court to dissolve the real estate deal.
He can't do it on his own, it requires an action by the court.
That means when the propety is sold, each brother will get 50% of the equity in the property.
Legally, you cannot force someone to stay in a real estate transaction.
