It has always been our value system that a transaction must be a win/win situation for both parties or no deal. With our initial buyer consultation we go over the offer process, and how we come up with our reccommendations and advice on what to offer. If our clients are inclined to low ball one of the points we make is that if you offer too low you run the risk of insulting the seller so that he won't even counter. The other is that you don't want to make an offer so low that the seller must bring money to the table for the priveledge of selling you their home. Most of all, we point out that if the seller feels like they are being taken advantage of, if there are issues with the sale, or if you need them to cooperate with a glitch, they may find themselves on the short end of the stick. Win/Win is always the best way to go.
Sometimes we have clients that are just bound and determined to offer the lowball deal, and so we offer it as they dictate, they end up losing the house because they insulted the seller, and then they listen the next time.
