making an offerif i make an offer, short sale or regular sale, can i give a time frame until my offer is valid, lets say 48 hours, or for a short sale a week, and if i dont hear back, the offer is no longer valid, so that i can make another offer on a different house? i dont want to wait month to hear back from a short sale, if at all.November 16 2011 - US00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
