The legal position, the procedures, the rates and the cut-off dates — every statement with a date and a source. Free, because facts are not merchandise. What follows from it for your case is settled in a conversation; the costed material is in the dossier.
50 pages with three fully costed examples, checklists for viewings and the escritura, question sets for the escribano and the agent, and the list of mistakes with what each one costs.
