Bear in mind that Rabo's special rate of 5% on the first 10K ends in the new year. They are now paying 4.3% regardless of the size of the balance.
You will get much better than this if you're prepared to lock your money away for a few months.
On the other hand, Rabo have an excellent credit rating and this may be important for a large deposit.
Regarding First Active - yes, the 5.22% rate only applies if the balance is up to €15,000 - so you'll need to transfer money out each month. No charges apply for transfers.
Might be worth considering putting some money in FA though... for example:
* set up FA E-Saver with balance of €14,900 - rate is 5.22%
* set up FA Regular Saver with initial deposit of €1,000 - rate is 7.15%
* transfer €1,000 per month from the E-Saver to the Regular Saver (AFAIK this must be done manually)
* the extra interest you'll get will be €157 approx after-tax over the full year compared to a 12-month deposit at Anglo at 4.76%.
€15,900 will grow to €16,662 approx.
Of course you'll have to weigh up whether the extra interest is worth the manual effort... and the risk that rates drop in FA.
