If a seller chooses to make a house unavailable, undesirable, and unmarketable then it commands a lower price.
Sellers are free to ask any price they wish! When we trade stocks we establish an "ask" price and if and when it meets someones "bid" price we have a trade!!!
There are no exceptions to the premise. With less marketing, which translates to less demand, the house sells at a lower price.
One again, houses sell on the steps with NO marketing, no photos, no viewings etc. My premise states that you either have to decrease the price or increase the value.
That actually supports my corollary rather than disprove it. The house with "Fang" sells at a lower price. When you remove the dog you increase the value of the property.
Houses sight unseen sell on the courthouse steps all the time but the price offered will assume potential risks.
