The buyer sometimes has no control of how fast the lender operates. Sometimes certain deals take longer than other to provide a commitment letter. If the buyer attached a Commitment contingency with the offer than the seller has to give the deposit back if the seller wants to back out of the deal. The best thing to do is to have a real estate lawyer look at the offer and at any other contingencies that were provided with it.
I think this question emphasizes the importance of quality communications between all parties in the process. Real estate should be conversational and not confrontational and issues are much more easily resolved when all parties have been actively conversing throughout all stages of the deal.
Good luck and keep us posted!
