(82)Action by Member States alone is likely to result in different sets of rules, which may undermine or create new obstacles to the functioning of the internal market. Since the objective of this Directive, namely the creation of an efficient and competitive internal market in credit agreements relating to residential immovable property whilst ensuring a high level of consumer protection, cannot be sufficiently achieved by Member States and can therefore, by reason of the effectiveness of the action, be better achieved at Union level, the Union may adopt measures, in accordance with the principle of subsidiarity as set out in Article 5 of the Treaty on European Union. In accordance with the principle of proportionality, as set out in that Article, this Directive does not go beyond what is necessary in order to achieve that objective.
