Expired listings expire because no one was willing to pay that price at that time. The sellers always learn this lesson and usually, when they have to sell, will re-list it at a lower price.
So, I'm curious, what would the price have to been for you to be more interested in it? I would never speculate what a seller will or will not take for their home. But the fact remains, they tried to sell it...would they have taken your offer?
