A relative is considering buying a 2 bed apartment in Dublin for around 200k. Property would be for an elderly parent who is currently paying rent at a high rate and also for visits to see him (2nd bedroom) and visit the other parent who lives nearby (they are separated). Idea would be that when the parent dies (hopefully not for a long time) property could be either used for kids to go to college - or if they decide not to go to college in Dublin then it could be rented providing some rental income approaching retirement. Any tax implications of giving a room to a parent in an apartment cost free ?
