I actually sold my house in 2005 using a price range. WIth Century 21, Not Prudential. Here is why we did it:
In spring of 2005 in my neighborhood there were so few homes on the market that there were large gaping holes in price ranges. In our case, there was maybe one house priced between 600K and 900K. We thought ours was worth 8xx K.
We priced it from the 770K to 850K (or something like that). It sold in the 820’s.
In our case, it was because we really did not know with more than 10% precision what it should sell for.
These days, in most areas, there is more than enough inventory to compare pricing relative to the competition. So it makes less sense than in the heady 2004-2005 days.
