90 day use of spanish property

No, you can stay a maximum of 90 days in any 180 day period.  So if you stay for 90 days, you must then exit the Schengen zone for the equivalent period, i.e. 90 days.

It is not per calendar year, so you can’t roll two 90 day periods back to back, it is a rolling 180 days.  If you plan to come back and forth, the best idea is to use one of the various free online Schengen Visa calculators to make sure you don’t end up  overstaying.

Overstaying by a few weeks could have a disastrous effect on any future residency application.

Hi and thank you for that. I am looking to apply for residency but may just use it as a hol home for 1st year till i adjust&get use to my new life rather than just move as never been to spain.

Ok, but just remember when you apply for residency, once your NLV has been granted, you have 90 days in which to take it up - i.e. move to Spain, then on arrival, 30 days in which to apply for your TIE.  Once you have taken up residency, you may not be absent from Spain for more than 10 months aggregate in the first 5 years.

So if you want to get used to Spain, do not apply for residency until you are absolutely certain you want to live here.  If you don’t really know the area, it may be better to come across for a few weeks and take a short term rental whilst you have a look around and decide what area would suit you best.

A successful residency application “stops the clock” on any counting of previous time spent here in previous 180 days, but it starts the clock on you migrating here permanently.

Hi i will be coming on an EU Passport so dont need NLV and i will come for a couple weeks to get a feel of areas hence i will use home as a holiday home for 1st year

In which case ignore previous 😁

EU Passport (Irish I presume) leaves you free to do just that - the only restriction there is that once Residencia is obtained, you must spend a minimum of 183 days a year in Spain to maintain continuous residency.  This of course will make you tax resident in Spain as well

Hi yes i know i will be in tax system once i spend more than 183 days so another thing to look into. Soooo much to sort lol

Correct, after 5 years, an Irish passport holder may be absent for up to two years.  UK passport holders are granted up to 5 years absence when permanent residency attained, but that was because of the deal that was struck by … I think it was David Cameron.  All other EU countries get 2 years absence allowed, but as a permanent resident, even if absent for more than 183 days, you remain tax resident in Spain

Good question that.. There are some pages that give you a 90-day calculator, but even that's con dusting
