As far as I know, McCarthy is completely opposed to this First Time Buyers' Grant. I don't know if any independent economist does support it. That doesn't mean he is right or wrong.
I am not opposed to it, probably because as I see it as a refund of the 12% VAT on the sale price of a new house.
Those who support it, often say that it should not be paid to First Time Buyers who are buying a house for €600k. (In practice, it probably doesn't matter, as I doubt very few FTBs buy a house for €600k with an 80% mortgage.)
If a FTB does want to buy a house for €600k, they have to borrow a minimum of 80% or €480k.
To buy this, they must have a combined salary of at least €137k ( 3.5 times 137 = €480k)
So, I think, that the minimum salary required to buy a €600k house is €137k.
There is no maximum salary to which this applies. So it helps anyone on any salary. Especially if they don't have the deposit.
It helps people on €137k
It helps people on €143k
It helps people on €171k.
€171k x 3.5 = €600k. That €171k figure is not relevant. So if Colm McCarthy used it, he got a minor calculation wrong.
But that does not in any way invalidate his argument. It certainly does not merit a headline "Colm McCarthy wrong about the €600k property."
The deposit is 10% of €220k and 20% of €380k, a total of €98k. If the State gives them €20k, they pony up €78k.
If they are on high incomes, the banks will probably give them a 90% mortgage.
So they can get a mortgage of €540k
They get €20k from the state, so they need to borrow €520k.
So they can get this grant with a salary of €148k.
If I have got my calculations wrong, it does not merit a headline "Brendan Burgess is wrong about €600k properties"
Likewise, if you have got your calculations wrong, it does not merit a headline "Gordon is wrong about €600k properties"
