While what you say does hold basis in fact, there is also another equation to take into account.
Quite frequently, owners (Dominicans and/or foreigners), are under pressure from spouses or family members to sell their respective or jointly held properties ASAP, for whatever reasons one can think of. The owner in charge may agree, and put the property up for sale, but at a price he/she fully realize that nobody in their right mind will ever pay for. They appease their spouses/family members by having the property up for sale, but at the same time fully realize nobody will come near the asking price.
So, while you may "believe" this property is for sale, it really isn't.
This happens more times than not.
