If you’re buying a house and agree a fee, some people may believe they’ve got a deal. Others may be a bit more cautious and wait until they have the mortgage approved before they tell friends that they have a deal. I would prefer to wait until the survey (due diligence) has been completed and I’m happy to proceed, even though I still don’t own it at that point, I know I would be happy to proceed and would only pull out if something unusual happened, like I suddenly lost my job. To me the deal is then agreed.
In reality the deal isn’t done until the contracts have been signed, but most people are happy to consider the deal to be done before that (rightly or wrongly), even though it’s not 100% guaranteed at that time.
This deal looks as though the new owners are happy to proceed, and are just tying up a few loose ends, so it looks like a done deal to me. Obviously they may decide to pull out at the last minute after putting in a lot of effort to buy the club, but likewise they could buy it and decide it was a bad move and decide not to invest further funds into the club, but does it really matter, they’ve agreed a deal and it’s almost signed off. A week or two in the timescale of a major takeover is minuscule.
