How do you define a 'finca'.  A finca is a farm not necessarily a building.  All of the licences from the Ajuntament are for Almacens.  An Almacen is a building for you to store your farm equipment.  Many Almacens have been built as bungalow and people are living in them but they are all illegal.  That said it does not mean that you will have any trouble.  The regional government have visited several properties which now have demolition orders issued by the Ajuntament (the same office which originally gave permission to build and were aware that bungalows were being built).  If your property was not one of the ones selected then I doubt you will have any trouble as the goverment do not have the money to investigate Ginestar any more.  It is just sad for the people that have been visited as they only did what everybody else did. Where in Ginestar have you bought as I do know which properties have problems.
