Usually the highest offer is the one the seller takes but there are times when a "cleaner" offer that is a little less money is the better route for the seller. In this seller's market, buyers should try to structure their offer to suit the seller's needs. The buyer's agent is well advised to talk to the seller's agent a try to figure out what the seller is looking for in an offer. Not so much the dollar amount but the terms. Sometimes sellers have a natural inclination to refuse to pay closing costs for a buyer. Even though an offer can be structured to net the seller the same amount he wants, some sellers have illogical or emotional reasons for not taking a particular offer that is otherwise very strong. In a multiple offer scenario the buyer may not get a second chance to present the best offer possible or to modify terms to suit the seller's idiosyncrasies.
In this fast selling market buyers need to be thoughtful about their approach to an offer.
