CPFC 2010, a group headed by London businessmen who wanted to buy the club, had made the purchase of the stadium in south London a condition of going ahead with the deal.
The stadium deal had run into a last-minute hitch and the club, founded in 1905, had faced the prospect of going into liquidation on Tuesday if no agreement had been reached.
Many of the club's financial problems stem from more than a decade ago when the ownership of the club and the stadium were separated under the terms of an earlier takeover.
"PWC has reached an agreement in principle with CPFC 2010 in relation to the sale of Selhurst Park. This enables the consortium to go ahead with the purchase of both the Crystal Palace Football Club and Selhurst Park," banking group Lloyds said in a statement.
"We can now confirm that there are no material differences between ourselves and the Bank of Scotland regarding the sale of Selhurst Park," CPFC 2010 said in a statement on the club's website.
"Whilst it is not 100 percent done, we are confident that all the main barriers have been removed."
