mortgage interest relief and rent

Hi all,
My husband and I rented out our house last year because I got a better job in a different county and we had to move.We're now renting a house.We're getting mortgage interest relief at source alright but are we entitled to rent relief on the house we are now renting?

You should not be claiming Mortgage TRS on a property that is not your principal private residence. You should notify Revenue immediately that you have been receiving Mortgage TRS on a property which is not your principal private residence or face penalties when they catch up with you.

What is the story if wife and kids are living in home and I'm paying rent in a flat where I work during the week. What rent relief am I elegible for as a married man?
