Hello, I moved to Ireland two years ago, but not "back" as I'm not Irish and had never been here before! But my daughter is married to an Irishman, I was newly widowed and nothing was keeping me anywhere else, so here I am, and intend to stay here forever. I am 69.
The move went very easily. First I moved in with my daughter in NI just across the border while I looked for a place just south of the border, because of Brexit. I have EU citizenship (German, though I am not ethnic German, just nationalised) so that much was obvious.
I decided to move into a BnB as a semi-permanent tenant this happened organically as a B&B owner suggested it. They had a big house that was only sporadically fully let so it made sense for them. It was a lovely big country house just ten minutes from my daughter in NI, but still south of the border. I lived very happily with the B&B couple for a year they were lovely people.
What amazed me were all the connections between people in rural Ireland, and how helpful everyone was. The B&B owners for instance were related to my daughter's next door neighbours and new her in laws well, which I suppose is one of the reasons they suggested I live there! And then my son-in-law's cousin who owned a town house with flats to rent had a new build flat to rent and I took that. It's gone well and I'm still here after a year, but I'm looking to buy eventually.
Everything went smoothly from start to finish. The biggest problem at the beginning was "proof of address". It's a vicious circle. You can't get a driver's licence or bank account without proof of address, and you can't get proof of address without -- well, proof of address, and while I was staying at the B&B I didn't have utilities bill etc. In the end I was able to get the B&B people to give me their utility bill with a note at the bottom confirming I lived there.
The next big problem was car insurance!!! I had a German licence and nobody wanted to insure me for that very reason. The only offer I got, through a broker, would have cost me a couple of thousand a year, even though I had a good no claims discount. The broker advised me to swap my licence for an Irish one and I did that, but of course there was the problem with proof of address.
Anyway, those problems overcome, I'm settled here but hopefully in about a year I shall have my own place and then I'll be needing lots of advice. Property up here is relatively cheap.
In three years time I will be eligible for Irish citizenship and I will certainly be applying! The only thing I dislike is the weather.
