Selling a home sounds simple, right? Find a buyer, sign some papers, and celebrate with a bottle of Rioja. But if you’ve spent any time in the Costa del Sol property market, you know it’s rarely that straightforward.

Sellers often assume that listing their property is enough to get it sold. However, factors such as choosing the right agent, presenting your home effectively, understanding the legal framework, and being aware of associated costs can significantly influence the outcome. Price it wrong, sign with the wrong agent, or fail to secure the right legal protections, and you could be stuck waiting for months, only to drop the price later or, worse, deal with a buyer pulling out without penalties.
Here’s what you need to know.

Not All Listing Agents Are the Same

Most sellers assume a listing agent takes some photos, posts the property online, and waits for buyers. Some agents do exactly that, put the listing online, sit back, and hope someone else does the work. These agents rely on luck instead of strategy. A good agent, on the other hand, is proactive, marketing your property properly, pushing it to their network, collaborating with other agents, and giving honest pricing advice instead of just telling you what you want to hear.

Some agencies specialize in high end villas, while others focus on mid range apartments. Some are area specific, meaning an agency based in Marbella might not be the best choice for selling in Benalmádena. Then there’s the marketing strategy. Some agencies invest in Google ads, some focus on social media campaigns, and others rely on their internal client network.

And then there are the agents who tell you exactly what you want to hear, that your property is worth way more than others have suggested. It sounds great at first, but after months of no interest, they’ll come back and tell you to lower the price to what it should have been from the start.

Be Upfront About Your Property

Some sellers omit key details about their property, whether it’s ongoing community disputes (read my community guide here), unpaid fees, legal complications, or structural issues. Some listing agents, in turn, choose not to disclose certain things to buyers to keep deals moving forward.

The problem? These things always come up eventually, often at the worst time, during due diligence, in a survey report, or right before signing when a buyer’s agent digs deeper. The smoother sales happen when everything is on the table from the beginning. If there’s an issue, a good listing agent will know how to position it correctly rather than let it become a deal breaker later.

Some vendors believe setting the lowest price possible and leaving no room for negotiation is a smart move. Even if the price is spot on, most buyers and their agents come in expecting a little flexibility. I’ve seen listings that were well priced from the start, but because the vendor refused to negotiate even slightly, buyers walked away feeling the seller was being snål (stingy). Sometimes that perception alone is enough to lose an otherwise serious offer.

The Listing and Commission Agreement: Know What You’re Signing

Before an agent can market your property, you’ll need to sign a listing agreement. This is a contract between you and the listing agency outlining their commission (usually 5% plus 21% VAT), the terms of exclusivity if any, and your obligations regarding payment.

Exclusivity: How It Should and Shouldn’t Work

I’m not a firm believer in exclusivity, at least not the way many agencies try to sell it. There are two types of exclusivity.

Bad Exclusivity: You sign a contract with one agency for a fixed period, meaning they control all viewings and access to your property. Why would you commit for months without knowing if they can deliver?

Good Exclusivity: You allow one agency to market your property but without time based commitment. You see if they’re actually generating viewings from the start rather than locking yourself in.

Exclusivity makes sense in high end villa sales and projects, particularly with agencies that have a proven track record of delivering on those types of listings. But exclusivity should never mean shutting other agencies out. A good listing agent should be working with other agents, not against them.

Why Giving Your Listing to Too Many Agencies Can Backfire

Another mistake sellers make is giving their property to every agency that calls them. It sounds harmless, you might think there’s no downside to having multiple agencies market your home. But when a property pops up with six different agencies, buyers’ agents get overwhelmed seeing the same listing multiple times. Some agents prioritize the highest paying commission rather than the best property for their client. And some buyers assume the property is already sold or that something’s wrong with it when they see it listed everywhere.

Less is more. One good agency is enough if they’re actually doing their job. Want to check if your property is being shared with the right agents? Ask for a Resales Online reference link once it’s uploaded. It should look something like R470000. If they can’t provide this, your listing might not be reaching the full network of agents.

The 5% Commission and What Happens Behind the Scenes

Commission (read my agent commission breakdown here) is one of the biggest surprises for sellers in Costa del Sol. Five percent is the standard here, higher than in many other countries. If the listing agency finds the buyer themselves, they keep the full 5%. If another agent brings the buyer, the commission is split 50/50. Some agencies first try to sell within their own network before opening it up to other agents.

This is why the first few weeks after listing tend to bring in direct clients from the agency’s database. If no deal is made, the property is then opened up to the full agent network through Resales Online and Inmobalia, where thousands of agents can match it with their buyers. Want to make sure your home is getting maximum exposure? Ask your agent when they’ll be opening it up to the full network.

The Costs of Selling a Property in Costa del Sol

Selling a home isn’t just about the sale price, there are costs involved. Here’s what to expect (not all might apply):

• Real estate agent commission: 5% plus 21% VAT
• Capital gains tax between 19% and 24% on the profit
• Plusvalía tax based on land value increase
• Legal fees typically between €1,500 and €3,000
• Energy certificate around €150 to €500
• Mortgage cancellation fees around 0.5% to 1%

Selling isn’t just about what you make, it’s about what you keep. Understanding the costs upfront avoids surprises later.

Final Thoughts

Selling a home isn’t complicated, but small mistakes can cost you time and money.

If you want a smooth sale, focus on choosing the right listing agency, not overexposing your property to too many agencies, having a strong legal setup, setting the right price, offering the right commission to attract agents, staging properly, and negotiating.

Get these things right, and you’ll be celebrating that sale with a bottle of Rioja sooner rather than later.
