Is there an offer low enough to be not worth offering?

[Padric Lynch]

After a couple direct mail calls, I have gotten some frustrated sellers. The responses range from "Your offer is unethical" to "We are absolutely not in the same ball park" and the typical "NO". The offer is always based off of my criteria, which comes directly from a spreadsheet. I figure that most of my leads will be losers. My philosophy is that if I spent the time and capital marketing, I should at least throw out an offer. Is this sound judgement? Or are there situations where it is just not appropriate to make an offer?
