CO-OP selling a property with HIGHEST AND BEST..

[Tom Server]

Hello I have a question, if anyone might know. A rehab property in a co-op has been put up for sale. The co-op is the one selling it since the original owner didn't pay their taxes the co-op became owners. So now the property is listed. my realtor is the listing agent. The co-op HOA wanted "Highest and Best". There were 4 other offers. Since my realtor is the listing agent, I'm pretty sure I have the Highest offer, its all-cash offer, no inspection and I have same things in the contract as the other offers. so, my offer is more and i should be the winner?

They were supposed to have a response yesterday and now my realtor states the HOA is meeting up again to decide.

I have nothing against me, no criminal record, good credit, job, income, savings, single male, no kids... could the HOA decline my highest offer the property to whoever they choose?
