Hi Kerry. I just saw your question and wanted to reply. The answer is a simple Yes!
There may be other circumstances regarding the offer like asset and income statements, pre-qual letter or a credit check. Your broker may be waiting for some documents that make offers more real.
So the question is now, how long did your broker have this "offer." Was it in writing and accompanied by financials statements, etc? Was it a crazy low-ball offer with no possible hope of acceptance. Yes, you should have been informed. Best.
