The problem at the moment is there is a lack of good rentals, and rents increased 10% in just a year. Therefore there is more demand than supply, and renters could get screwed by this change. So that is why I wonder if the government won't bring in some form of rent control. But guessing they are doing a 'wait and see' approach, so they have some evidence.
Are you sure? If houses rise 20% in a year, you would expect rents to rise also
