I see, it is however hard to see just which properties have dropped and which havent and if they need to drop further or what. Prices seem to fluctuate wildly.
Here is one example: http://www.fotocasa.es/Building/Building_Detail.aspx?ai=127310392&opi=105&tti=1
Now would you say something like that, at that price is already priced to sell or needs to drop 30%?? further?
Obviously its hard to say looking at an online add, but there are many like this, same size, same condition, same location.
Its difficult to know what the true price is when these similar properties range from 40-100k
