Most repeat homebuyers don't like selling their current home until they know where they're going. However, most repeat homebuyers can't qualify to buy before selling. So, how do you structure a contingent-sale offer so you get what you want without being homeless?
Sellers prefer offers that aren't contingent on the sale of another property. If the buyers' home doesn't sell, they can't buy the sellers' home -- and the sellers are stuck looking for another buyer.
