Question for Realtors re Contingent Offer

[Bruce Woodruff]

So let's say that you've got a house for sale and you accept a buyer's offer contingent upon the sale of a property they own.

Then you get a cash offer from another party wherein their Realtor tells you that in your state, if you, the seller, gets a cash offer, then Buyer 1 has 72 hours to come up with their money or lose their contingent offer.

Not getting anywhere looking this up, so BP is the go-to info machine.

Something sounds off about this.....?
