Is this true ? I didn’t realise… surely one can get permanent residence if they own a house? It must be different in different countries too…
Yes it is true and applies to UK citizens throughout most EU countries.
No, you can't just get permanent residence if you own a house. You need to show tax records for previous years. Here in France, the deadline for UK citizens to apply for a residence permit (carte de sejour) is the 30th June. No idea what the process will be for anyone arriving after that.
We have friends who have decided to move from here to Spain, but they had to be there for 3 months prior to Dec 2020 in order to qualify for a residence permit there.
You can no longer just rock up and buy a house. You will be limited to 90 days in any one period and yes, customs are now stamping passports when you cross the channel so it is all recorded somewhere.
You may also have issues with qualifying for healthcare, registering your car and having a valid driving license.
You may not be eligible to work either.
Brexit has had a huge impact on things that UK citizens have previously been entitled to/taken for granted and it will be interesting to see how this is reflected in programmes such as Place in the Sun.
