Looks like I have to explain further, since someone gave me a "thumbs down" probably figuring I was trying to push my own buyer off the fence.
We had a listing that was languishing on the market, and we'd had many showings. One couple had seen the house 3 separate times, but they had a house to sell, too. They were very hesitant to bring an offer, with a house-sale contingency because they were concerned that we would not accept one.
Recognizing that we were hurting ourselves by "sitting" on the market, we made a pre-emptive strike by writing up a reverse-offer to this couple, with a house-sale contingency.. 30 days to get under contract, 90 days to close, at 98% of our list price... this got the buyer off their seats, and we began negotiating in earnest, and came to an agreement 60 days to get under contract, 90 days to close @ 96.5%. This is a deal that never would have happened, since we had a very tentative buyer, their property wasn't on the market yet, and I doubt they would have ever made the move.
Our next step would have been a price reduction, which would have taken us BELOW 96.5%... so this was a win-win!
