How long will take a builder to counter back or accept offer

[Jaimie Chen]

I am working my first deal to help my client to get his home settle. It is a quick move-in property and will be ready in a month.

The sales person was really hard to talk to lower his price (or my communication skill needs more improvement), but he finally gave in and accepted our low offer orally. He mention he will give us response next day. I mentioned low, it is low, but not the lowest I can find on the MLS records under same condition.

As I said this is my first transaction, my mentor told me just wait and see. But I really want to know how long the wait is reasonable. I don't want to call back and check to give builder an impression that we have to have that house.  I just need to know if we should go ahead to move on or keep waiting.

PS. Property is in DFW area. Sales mention he is selling 6-7 house a month.

Thanks.
