I made a written offer yesterday, with a 24 hour deadline. The deadline came and I phoned the agent, no answer, with an SMS about half an hour later saying he would let me know asap. 2.5 hours later, here we are! I've never not had a response before, from vendor or agent! I have no problem walking. It's strange. My mother is an agent and is flabbergasted that I've heard nothing. I suspect the agent didn't convey the deadline.
