Members of Bournemouth's supporters' trust have voted to support the club's proposal to sell their Dean Court ground for �3.5m and lease it back. A secret ballot of members of the Community Mutual (CM) saw 258 vote in favour, 17 against and three abstain.
The proposal will now be put before the club's shareholders at an Extraordinary General Meeting on Friday evening.
The CM holds two "golden shares" in the League One club, which gives them 51% of the voting rights.
However, in a statement, the Mutual has said that the club now needs to show it can adequately restructure its business before its votes are cast.
Earlier in the week, Cherries chairman Peter Phillips reiterated that he would be forced to quit if the proposal is thrown out at the EGM.
"I've worked as hard as I can, and done my very best to keep the club alive in what have been very difficult times," he told BBC Radio Solent.
"We got some things right and some things wrong, but we've always tried to do the best for the club.
"If the vote goes against us on Friday, then there's only one conclusion, and that is that myself and the rest of the board would have to resign."
Phillips has also warned that if the proposal is thrown out, that the club would be forced into receivership.
If the deal goes ahead, the stadium would belong to a property company, with the Cherries having to pay rent each month.
But a supporters' pension scheme, headed by Dave Stone - a fans' representative on the football club's board - is still hopeful of raising enough money to buy back the stadium from the new landlord.
