Mr. Kieran Culhane:

We do not know either. We use the data. The census does not ask questions on landlords; it asks the tenant whether they rent their property.

It does not ask who a tenant's landlord is or for any information about him or her. As Dr. Byrne pointed out, landlords can sell and move in and out of the market without the property moving in and out of the market. There is turnover in there. We have seen that in any data sources we have looked at. Part of this exercise will be trying to see if there has been anything significantly outside of what would usually be expected in a functioning market to be seen over recent years. That is one element we can look at in the exercise we are carrying out with the RTB.
