Advice please. Have 2 interested buyers, one wants exclusive rights.
I have a facility that was used for metal refining.  I started advertising it back in July, I immediately had these 2 interested buyers, we'll call them A and B.  Buyer A flew in first and gave me a deposit but has not been able to close the deal.  So now 4 months later I contacted buyer B who is interested and they want exclusive rights for a couple of months to give them time to work on this deal.  Buyer A is still saying they want to buy but just had some delays in getting their funding put together.  

Would you give buyer B exclusive rights for a few months?  The money that this deal will bring in is preferred to be in sooner rather than later as we're needing it to fund other deals, although I feel like buyer B might walk away if they can't have some guaranteed time on this.  I'm not highly confident that buyer A will come through, although it's definitely possible.

Thoughts?

You give a deposit, then after a certain amount of time (typically concurrent with the waiving of contingencies) it becomes non-refundable.  Then there's a deadline to close the deal or else the purchase contract becomes invalid.\n\nYou might be able to structure this with Buyer B if you choose to go with them.  But is B really that much more reliable than A?", "replies": [{"id": "ce17yag", "text": "Good info thanks.  We're very new to commercial real estate and these kind of deals are all new territory.  I think I'll seek out a lawyer to get me a contract like the one you're describing, we'll be needing it.\n\nI don't know if they're more reliable I just think they have access to the money to follow through, vs. buyer A was seeking other peoples money to finish the deal.  It's a good question you're asking, I'll have to think about this a bit more.\n\nThanks for the input!", "replies": [], "depth": 2}], "depth": 1}]
