How the ninety-day rule is quietly reshaping coastal buyers

September on the coast rarely announces itself with headlines. The beach bars are stacking their chairs a little earlier, the estate agents' windows in Fuengirola and Jávea are still full of the same handful of villas, and the market is doing what it usually does this time of year: quietly resetting itself before the autumn viewings begin.

What is different this year is not a single number but a set of smaller shifts, the kind that only show up when you talk to enough buyers, lawyers and lenders across both coasts. Borders, budgets and who is actually doing the buying have all moved a little. None of it is dramatic. All of it is worth knowing before you start looking.

We spend our days on the Costa del Sol and the Costa Blanca, not selling anything, just paying attention. Here is what that attention has turned up this September.

The days you are actually allowed to stay

For anyone holding a British passport, the arithmetic of owning a Spanish home has not changed in years, but it is being enforced more visibly than it used to be. Britons are non-EU nationals now, which means the ninety days in any rolling one hundred and eighty at the Schengen border, no more, no exceptions for owning a house here.

What has shifted is the checking. The EU's Entry/Exit System, which logs arrivals and departures electronically rather than by passport stamp, has been phasing in at Spanish airports including Málaga and Alicante since last year, with ETIAS travel authorisation expected to follow later in 2026. Overstays that used to slip past a tired border officer are now easier to catch, and harder to argue away.

We are seeing this land in ordinary conversations. Buyers who assumed they would simply spend "most of the year" in Spain are doing the maths properly for the first time, some looking at a non-lucrative visa if they want to be here for longer stretches, others deciding a shorter, more concentrated few months actually suits them better anyway.

The people who plan around the ninety days tend to enjoy the house more, not less. A clear limit forces a real decision about how you want to use the place.

Who is actually buying this year

British buyers remain the largest single nationality on the Costa del Sol, and a strong presence on the Costa Blanca too, but the mix around them keeps widening. In our own enquiries this year we have noticed more Dutch, Belgian and Polish buyers than a few years ago, alongside a steady Nordic contingent drawn by the direct flights into Málaga and Alicante through the winter months.

None of these buyers face the ninety-day limit as EU citizens, which changes how they shop. They ask fewer questions about visas and more about school terms, ferry schedules to their home country, and whether a property will suit them for four months a year or twelve. The Costa Blanca, with its longer tradition of northern European retirees, is feeling this shift earlier than the Costa del Sol, where the buyer profile has always been more varied.

Prices holding their shape, mostly

Neither coast is behaving the way headlines about "the Spanish property boom" might suggest. Prime coastal addresses, the front line in Marbella, Estepona, Jávea and Altea, continue to hold their value well, with sellers in the best positions rarely needing to negotiate hard. A short drive inland, or in towns that depend more on Spanish buyers than foreign ones, the picture is calmer and prices move less.

We would rather describe this honestly than dress it up: the sharp, headline-grabbing rises of a few years ago have given way to something steadier. That is not a warning and it is not an opportunity dressed as urgency, it is simply the pace the market has settled into this year.

Supply, and where it is quietly coming from

New-build supply on both coasts is still constrained by the same things it was last year, planning timelines, labour availability, and the cost of materials, so completion dates keep slipping by a few months rather than arriving early. Anyone buying off-plan should ask their developer for a realistic date, not the optimistic one on the brochure.

There is one supply thread worth watching that has little to do with construction. Some owners who bought with the idea of spending long stretches in Spain, and who have since worked out that the ninety-day limit makes that impossible without a visa, are quietly putting those homes back on the market. It is not a flood, but it is a real and slightly unusual reason for resale stock to appear in areas that otherwise feel tight.

What this means if you are starting your search now

If you are a non-EU national, work out your day count before you fall for a particular street. It shapes everything else, from whether you want a flat you can lock up easily to whether a longer-stay visa is worth investigating before you buy rather than after.

If you are an EU citizen, you have more freedom to choose a coast based on rhythm rather than paperwork, so it is worth spending real time in both regions across different seasons before deciding which one suits the life you actually want to live.

Wherever you sit, treat this September the way we do: as a good moment to look closely rather than move quickly. Talk to a local lawyer about the visa question if it applies to you, ask a mortgage broker what a non-resident loan actually costs once fees are in, and walk a street at midday as well as at dusk before you commit to it.

If any of this raises a question specific to your situation, we are glad to talk it through and, when you are ready, introduce you to the local lawyers, brokers and advisers we trust on both coasts. No pressure, just a proper conversation about what would actually work for you.
