Ok, know it, they do a half marathon every February but cancelled this year for whatever reason. An awful lot of Irish have purchased out there and property is very plentiful and cheap. Don't know why you would borrow money when you already have it although I also understand what you're saying about the CGT. Wouldn't you have to pay that tax regardless at some stage, unless you're thinking of bringing it with you?
On the other hand, flights are cheap, rentals aren't costing a lot out there and you could have a huge amount of holidays for €75k to MOST PARTS OF Spain. I know it's not a big amount of money, but think about it, there'll be plenty of other costs associated with buying and owning a property over there, never mind getting a phone call in the middle of the night over in Ireland telling you something has gone wrong.
