Going through the Variant Perception report on the perilous state of Spain's banking system, I couldn't help stopping and thinking hard about this point from the Spanish newspaper Expansion:

The valuation of the guarantees of the mortgage book of the cajas and banks and of its real estate gains importance. The thirteen companies tied to financial entities represented 47% of all real estate appraisals in 2007. The valuation of these real estate assets has taken on new importance for banks in the context of the current economic recession. The valuation of the mortgage guarantees and of the real estate assets they are taking on through the courts and debt for equity swaps is key to calibrate the solvency of the financial system. This situation has placed the focus once again on the links between banks and the real estate appraisers that goes beyond in many cases a mere commercial relationship.
