MADRID.- Something is going on in the housing sector and there seems to be light at the end of the tunnel. The 'stock' of apartments on sale has been almost totally absorbed in some Spanish regions due to increased demand, according to information published in the report 'The process of adjustment of the property market in Spain and the Region of Madrid' published by Caixa Catalunya. The financial institution also indicates that the price of some of its housing developments has already increased by between 3% and 5% in those areas where the surplus offer is now almost inexistent.
