Another thing that often happens on this post is a massive generalization about realtors, mostly to the negative side. While there are sheer numbers of poor realtors one pleasant side effect of this downturn will be to shake the industry out somewhat.
There is never any harm in submitting lowball offers. What the buyer needs to be aware of is that if you submit a hundred lowball offers don’t be surprised if you get a hundred rejections. That doesn’t mean you shouldn’t submit the offer, you should just be cognicent of the probable outcome. In terms of “offending” the other agent that is never a concern. It is very simple to submit a lowball offer without offending the other agent or the sellers, ESPECIALLY in this market. If they will not entertain the offer then they will tell you.
