Property Portals Guide Costa del Sol (2026)

The Truth About Property Portals

If you are starting to look for a home in Spain, chances are the first thing you land on is a property portal. Idealista, Fotocasa, Rightmove, JamesEdition, Pisos, Milanuncios. They look like the answer. Thousands of homes, beautiful photos, maps, filters, the dream.

And they are useful. They help you get ideas, compare styles, explore areas. But here on the Costa del Sol they also come with a catch. The photos may be real, the price may not. The property may have sold years ago, or the price may have moved a long way up. With new builds you often see starting from numbers that look great, but the unit that once started at that price might have sold long ago and the new starting point is much higher.

There are rules about what should appear in ads and when things should be updated, but they are rarely enforced in a way that protects buyers from stale or incomplete information. As long as an agency keeps paying for its ads, the listing often stays online whether or not it is accurate.

Take a villa project launched off plan in 2022. Prices may have started around five hundred thousand euros, modern detached homes that looked like a steal. They sold quickly. Fast forward to today, the project is completed, every villa is sold, and resales are worth far more. Yet the old ads still sit on portals. They catch eyes, generate calls, and keep the phones ringing.

Why This Happens

Think about it. If you are an agency or agent and you had a great looking villa or apartment at a headline price, why remove it once it sells. It means logging in, taking the time to remove it, and losing the attention it generates. That listing is a magnet. You can always tell the caller, sorry, that one just sold, but what are you looking for. You still got the lead.

Some listings are left there deliberately as bait. Others are simply forgotten because there is no single rule or penalty that forces anyone to take them down.

Spain does not have one national MLS that every property must pass through. In the United States or Canada one central database feeds the portals. Spain is fragmented. Different regions have their own networks such as MLS Nacional, Agora MLS and local groups in Madrid and Valencia. They are not connected and they are not mandatory.

On the Costa del Sol we do have serious private MLS systems. Resales Online and Inmobalia. These are paid databases used by agencies for agencies, not public portals. They require proper property details such as the referencia catastral and they track status changes much faster. Almost every serious agent on the coast checks them first.

Andalucía also asks for a simple consumer information sheet when a home is advertised or shown, the Documento Informativo Abreviado, and Spain asks that an energy performance label appears in sale and rental ads. In practice you will still see in process or nothing at all. The rules exist, the enforcement is uneven, which is why portal information can feel patchy.

The Shop Window And The Stockroom

Here is the best way to picture it.

The portals are the shop window. Big displays, plenty to look at, some real, some not.

The stockroom is Resales Online and Inmobalia. This is where professionals actually check what is in stock today. These systems cost serious money, they require proper references, and they show changes in availability faster than public portals. Buyers do not see them directly, but almost every agent on the coast uses them daily.

Then there is the locked cupboard. That is each agency’s direct listings, the properties they have been hired to sell themselves. It is up to each agency and agent how they handle these. Sometimes they are fed to portals and shared directly. Sometimes they are uploaded manually and then forgotten. And sometimes they are kept back on purpose. These are pocket listings. An agent may first pitch the property to their own clients, then to colleagues, and only later push it onto the MLS if needed. The reason is simple. If you can place the buyer yourself, you keep the entire commission cake.

The Big Public Portals

Idealista is the giant in Spain. If you type buy property in Spain into a search engine, Idealista is usually at the top. That is why every new buyer ends up there first. It is fantastic for browsing and in some cases it is exactly where you should look. More economic properties under two hundred thousand euros often appear on Idealista before they are anywhere else because many vendors at the lower end do not want to use an agent or cannot afford it, and the 300-900 euros it costs to publish on Idealista is worth it for them. If you are hunting for a bargain apartment you may actually find it here first. The flip side is that for mid range and above, many of the dream listings have been sold for years. Idealista still gives you a feel for neighbourhoods and pricing, but always double check availability before you fall in love.

Fotocasa and Habitaclia are household names in Spain. You will see their ads on TV, online, and plastered across the internet. They have good coverage and plenty of mainland Spain listings, including the Costa del Sol. They are useful if you want to compare or cross check against Idealista. But the same issues appear here too, sometimes even more so. Duplicates, old pricing, and listings that have been gone for years are common. I know because I was guilty of this in the beginning as well. I once kept an apartment I had already sold listed there for years and still got the occasional call. Mostly because it was complicated to take down, and the only thing pushing me to do it was my conscience.

Pisos, Spainhouses.net, Yaencontre, Milanuncios are less dominant but still come up in searches. Milanuncios behaves like a classifieds board. You can look for a sofa and end up with a flat. It is messy, but sometimes private sellers use it for low value properties. If you are after something cheap or quirky you might stumble across it here. Be careful with any request for money before a viewing.

Rightmove Overseas is the portal every Brit knows. In the UK Rightmove is king. In Spain, not so much. It comes up again and again because British buyers naturally type Costa del Sol Rightmove into search. It is trusted at home, which is why people use it here. Just know that the updates are rare and the prices you see are often outdated. I once had a client send me a Rightmove listing for a new development that showed three bedroom penthouses under four hundred thousand. The truth was that project had sold out two years earlier. The listing was never updated.

JamesEdition is the glossy luxury one. If you are searching for a trophy home in Marbella you will probably land on it. It looks beautiful and it is great for inspiration. But the properties you see there are not always live availability. Think of it as a magazine rather than a stock list. A villa listed there in 2023 at two million may still be up even if it sold long ago and its neighbor resold for far more.

A Place in the Sun is UK driven. It is famous for the TV show and spends heavily on marketing in Britain. That is why the name comes up so quickly in searches. It is good for browsing and gives buyers a sense of the lifestyle, but just like the others it shows more of the dream than the reality.

Why ads often feel off

Meters are counted differently here. You will see metros construidos which includes shared elements and metros utiles which is the space you actually use, and terraces are sometimes counted at a percentage. That is why one ad can say one hundred and twenty square metres and another says ninety five for what looks like the same flat. Map pins are often approximate because sellers mask exact addresses, so the place can appear to move when you get the real location. Paid positioning exists, so the same teaser can sit on top for a long time. Ads also live a long time and can be renewed with one click, which is how zombie listings survive.

The Professional Portals

Now the part buyers never see.

Resales Online is the backbone here. Almost every serious agency on the coast has access. It costs big money, it is vetted, and it covers thousands of resale listings. It also carries new developments, but it is not the gold standard for them. Good agencies still rely on their admin teams to keep the ever changing developer price lists up to date. If it is not on Resales Online there is a good chance it has sold already or it is a pocket listing.

Inmobalia is strong in Marbella and connects many agencies as well. It also carries new development stock and works as both an MLS and a CRM.

It happens often that clients send me an Idealista or Rightmove link thinking it is available. I always check it first. If it is still active, great, I will book it for us to view. If it is gone or wrong, I explain the situation. Sometimes it is best that the client hears it themselves, so I suggest and even insist they call the number. When they get the excuse or hear that “it was just sold”, the point is clear.

Why New Developments Are Extra Tricky

Resale listings are one thing. New builds are another.

When a developer launches a project, prices rise quickly. Sometimes after each sale, weekly or monthly depending on demand. If buyers rush in and reserve quickly, prices can climb fast. The market is ever-changing and that means the from price you see on a portal is almost always already out of date. Even on the developers own sites sometimes.

Add in that an agency or portal needs to constantly update a few hundred new developments from different developers with different systems, contact means and procedures… you start seeing why its almost impossible to be fully up to date.
So what happens. A portal shows a three bedroom at four hundred thousand. A buyer calls. In reality the cheapest available unit is now six hundred thousand. The ad did its job though. The call came in and you get the chance to work on that client.

This situation is not unique. It happens in almost every new development. A project might launch with two bedroom apartments starting under three hundred thousand. A few months later the cheapest units are already above four hundred, yet the old ads for three hundred are still online. Buyers see them, call, and get reeled in. And it is not only on portals. Many agency websites show the same outdated prices because their listings are not updated fast enough either.

The fix is simple. Ask the agent, agency or developer for the live price list and availability dated that day.

Exclusive versus open listings

When a seller gives the mandate to only one agency you tend to see cleaner advertising, one set of photos, one price, and faster updates across portals. When a seller gives the listing to many agencies you get several versions of the same home, different photos, different prices, and different stories. That is how duplicates happen and why the same apartment shows up five times.

Why Agencies Play Along

It is not always malicious. Sometimes listings stay online because nobody has time to take them down. Sometimes the system is manual and clumsy. But yes, sometimes it is because an agency wants to look bigger. More listings equals more credibility. Sometimes it is because a listing gets calls constantly and the agency does not want to lose that pipeline. Portals reward quantity, not accuracy, so the incentives are clear.

How To Use Portals Wisely

Use them for ideas. Use them to see neighbourhoods, styles, building names. Save listings that inspire you. But do not take price or availability as fact.

Before you fly out, ask your agent to double check the links you saved. If they are good, great. If not, better to know in advance.

If you are looking at new builds, ask for the latest price list and availability from the developer or the agent. If a listing looks too good to be true, it usually is.

Controversy Done Right

This is not me attacking portals. They are useful. They are the shop window and everybody uses them. But buyers deserve honesty about how they really work here.

Every agent on the coast has had the same conversation with clients. Every buyer who has already gone through the process eventually figures it out. If you are new, it is better to hear it now.

And to be clear, this is not about blaming portals. They have value, they give people a starting point, and they have helped millions of buyers begin their search and do conduct sales, there are real listings, and some are up to date. The challenge on the Costa del Sol is how the data is handled. Some listings are connected directly and updated. Others require manual input. And a common trend is that some are kept online long after they should have been removed, simply because they still generate calls. There is no single nationwide MLS that forces consistency, so naturally there are gaps.

That means portals here are best used for inspiration, not confirmation. It is not a flaw of Idealista, Fotocasa, Rightmove, or JamesEdition. It is simply how the Spanish market works today.

The Price Oriented Client Trap

This is where portals may cause the most damage. Price oriented clients spend weeks or months saving beautiful villas and apartments they think are real and within budget. Then I step in with the facts, and suddenly I am the bummer agent telling them those dream homes are long gone.

Some clients accept it, especially when I prove it. Others think I am the one lying and showing them worse options. Some go with the agency that advertised the property on the portal for less. They show up excited, only to discover reality. By then it is either awkward, too late, or both.

Very few actually walk away from the agent or agency who misled them. Most are simply disappointed. A handful have come back to me afterwards and said you were right, we showed up and the price was exactly what you checked. But at that point it is often too late for me to help with that specific project or home, because the other agent has already registered them with the developer or vendor. That registration form locks the buyer to that agency for that home for a period of time, which means even if they later realise they were misled, the commission is already secured (this can be fought and the registration can sometimes be swapped with express writing from the client)

Final Word

Portals are not evil. They are just not always the full picture. They can be frustrating, and they can waste your time if you believe everything you see. It is especially discouraging when you find several homes you really like, only to learn later that they are either sold or priced far above your actual budget. A professional does not tour a client on fantasy prices and then let the developer’s live price list deliver the bad news that every project is thousands higher.

The Costa del Sol is different from the United Kingdom, different from the United States, different from the transparency you find in Sweden. Here, there is no single nationwide MLS. There are private systems, agency portfolios, and a lot of marketing smoke.

If you understand that, you will save yourself a lot of disappointment. Use the portals to dream, use an honest client oriented agent to see what is real, and remember that the shop window is not the stockroom.

A final note on standards. Spain is moving toward more professionalisation and some regions are rolling out agent registers. Andalucía has its own push which will tighten things further. Standards will keep improving. Until then, take portals as inspiration and let the stockroom confirm what is real today.
