Hang on a minute now! They don't save €1,000 in CAT. They save 33% of whatever that €3000 has increased to whenever they would have inherited it.
If the increase was indeed 100% then the 3k slice of house (about a square meter's worth!) would have increased to 6k. CAT, if inherited at that point, would be 2k. If sold at that point, CGT would be only 1k. The benefit is not wiped out completely.
This assumes the child sells the house on the death of the parent(s) and has already exceeded the CAT threshold. Should the child.choose to live in the house as PPR, then the CGT falls away and the benefit is 2k per annual transfer. (Minus any stamp duty which is quite small)
True, but let's assume they already own a home.
It can work - in certain, admittedly limited, circumstances. Let's assume we've got a property owner who has:
A) a valuable, mortgage-free property in which they intend to remain living for the rest of their life.
B) not a lot of free cash
C) a child to whom they would like to leave the house to in their will
D) said child has already received an apartment worth €335k from the parent
E) said child is a practicing solicitor who can handle the transaction in firm.
