&gt; <i>Just because another buyer came in &quot;after&quot; that had a better price changes nothing;</i><p>If the broker landed what was truly the highest price at the time, then you&#x27;re right.  However, the implication is that the broker managed to get the deal done (ie, misrepresented the market-value) and then collected money in a side transaction when the second transaction completed.  That&#x27;s pretty dirty, if it&#x27;s the case.
