I think part of the issue is the "you won't know until you try" mantra of the resale boards. By this I mean, you could, for example, have a number of contracts for XYZ Villas listed at $150 per point, to which many will apply the aforementioned strategy and try to offer $5, $10, or even $20 below list price because "you never know, and if you keep trying, sooner or later someone will say yes". Then someone DOES say yes and possibly another, and NOW, the "market" price in some minds (because look at the ROFR thread) is $130 per point. Rinse and repeat, and you have people applying the mantra and offering $110 on an already downward adjusted $130 per point contract (or even one that the seller hasn't moved off their original list price because it's not that old) and finding "recalcitrant" sellers.
Now, in the current market, downward pressure should be expected, compared to last year's very bullish market, and I'm not saying this applies to anyone in particular or specifically in this thread, but I can see the exuberance to get that "sweet deal" driving offers well ahead of where natural downward pressure may take the market.
Just a thought.
