I think the only thing you can do as a buyer going forward is pay extra close attention to the closing date in the contract. I know one broker told me Disney refuses to accept any contract with a closing date less than 60 days out. I would just make sure your closing date is only 60 days out as that’s the best it is going to be.

It would also be wise to decide if this extra time they’re taking is worth it to you to buy resale. If I could get a good deal, it would be worth it to me, but that’s a personal decision.
I’m guessing a lot of the frustration expressed on here is because they are changing course on notification times. FWIW, I would be incredibly angry and frustrated too as I am very impatient. My advice is to take a deep breath and try to focus on something else going on. If you decide to offer again should any of these get taken, now you know the rules have changed. I am sorry that y’all are the guinea pigs on this change. It is just plain selfish that they’re taking this long so they don’t have to pony up the money sooner.
