Hi all, Opened a bit of a can of worms here. In relation to some of the questions raised above, the rent charged is possibly a little below the going rate for the area (by €30/month, max), but my friend had just reckoned it was a good deal and had to get somewhere fast.
In relation to rent tax credit, yes they have this from another rented house. When i was renting i found that you apply for this tax credit and you still had it years later, even though you could have moved to ten different rented houses.
The landlord did not ask the tenant to forego this tax credit, or to give free/reduced rent etc. The landlord did say to the tenant that he had got a disabled persons grant and it is obvious from the apartment that it is for disabled/elderly people.
