In Spain the seller normally pays the estate agent commission, not the buyer. On the Costa Blanca, Costa Cálida, Costa del Sol and Costa Almería the fee is typically 3–6% of the sale price plus IVA, agreed in the seller's listing contract and deducted from the seller's proceeds at completion. As a buyer you almost never pay a separate commission to the selling agency — the price you see already has the fee baked in. That single fact changes how you should read every listing and every "friendly" agent on the four costas.
But "the seller pays" is only half the story. Because the agent's fee comes from the seller, the selling agent legally and practically works for the seller. The property is advertised across a dozen portals and agencies (a normal Spanish quirk), so you can end up in dual agency, where one office represents both sides. This guide explains exactly who pays what across the four regions, why API registration matters far less than most buyers think, what dual agency means for your interests, and the real legal safeguards — the notary, the nota simple and your own lawyer — that actually protect you in 2026.
The seller pays. When an owner instructs an agency on the Costa Blanca or elsewhere, they sign a nota de encargo (listing mandate) that sets the commission percentage. That commission is a cost the seller nets against the sale price. For you, the buyer, the practical implications are:
That last point is the crux of everything below. It does not make agents dishonest — a good Costa Blanca real estate agent earns their fee by finding you the right home and steering a complex cross-border transaction to completion — but it does mean you should understand whose interests the fee aligns with before you rely on any advice about price.
There is no legally fixed rate in Spain — commission is a free commercial agreement. In practice the market has settled into fairly consistent bands, with the Costa del Sol's higher-value stock often carrying slightly lower percentages (because the euro amounts are large) and cheaper inland or village properties sometimes carrying a fixed minimum fee.
| Region | Typical commission (of sale price) | Notes |
|---|---|---|
| Costa Blanca (Alicante) | 3%–5% | Often a fixed minimum (e.g. €3,000–€6,000) on lower-priced homes |
| Costa Cálida (Murcia) | 3%–5% | Similar to Costa Blanca; buy-to-let stock common |
| Costa del Sol (Málaga) | 3%–6% | Higher property values, shared MLS reduces the effective split |
| Costa Almería | 3%–5% | Rural and repossession stock may carry fixed fees |
On new-build developments the developer pays the agent's marketing commission — again, never you. This is why buying an off-plan unit through a reputable agency usually costs you nothing extra versus walking into the developer's own show home; the developer allocates the same commission budget either way. If you are weighing new against second-hand, our guide to off-plan vs resale on the Costa Blanca breaks down the cost and risk differences.
Commission is a seller cost, but you still have your own transaction costs on top of the price. These are the numbers that actually leave your account, and they vary sharply by region because transfer tax is set by each autonomous community:
| Region | Resale transfer tax (ITP) | New build |
|---|---|---|
| Costa Blanca (C. Valenciana) | 9% (from deeds signed 1 June 2026; 11% band above €1M) | 10% IVA + 1.4% AJD |
| Costa Cálida (Murcia) | 7.75% | 10% IVA + 1.5% AJD |
| Costa del Sol (Andalucía) | 7% | 10% IVA + 1.2% AJD |
| Costa Almería (Andalucía) | 7% | 10% IVA + 1.2% AJD |
Two things trip up buyers here. First, on the Costa Blanca the transfer tax dropped from 10% to 9% under Ley 5/2025, but the reduction applies to deeds signed from 1 June 2026 — it is the notary signing date that counts, not when you paid your reservation deposit or arras. Many competitor sites still quote 10% for Alicante and 8% for Murcia; both are out of date. Second, the tax is charged on the higher of the purchase price or the regional valor de referencia (a cadastral reference value). If you negotiate hard and buy below that reference figure, you may still be taxed on the higher number — so ask your lawyer to check the valor de referencia before you agree a price.
Add notary (~0.2–0.5%), land registry (~0.1–0.25%), your independent lawyer (~1% + IVA) and a gestoría (~€300), and the rule-of-thumb total on top of the price is roughly 10–13% for a resale and 12–15% for a new build — the lower end in Andalucía, the higher end on the Costa Blanca.
"API" stands for Agente de la Propiedad Inmobiliaria, a historic officially regulated estate agent qualification. Here is what surprises most international buyers: since a 2000 liberalisation, you do not need to be an API to sell property in Spain. The profession was largely deregulated, so anyone can legally operate as an estate agent nationally. API registration in Spain is therefore a badge of extra professionalism, not a licence you can rely on to guarantee competence or protect your money.
Two regional wrinkles matter on our costas:
Because registration is patchy, do not treat any acronym as a guarantee. The things that actually protect you are professional indemnity insurance (ask to see it), a written client-money handling procedure, transparent contracts and — above all — your own independent lawyer who does not work for the agency or the seller.
Dual agency is where one agency represents both the seller and the buyer in the same deal. It is extremely common on the Spanish costas because of how the market is structured: sellers list with multiple agencies, agencies share listings through informal MLS networks (especially on the Costa del Sol), and commissions are frequently split between the "listing" agent and the "introducing" agent. The office showing you the villa may not be the office that signed up the seller.
The conflict is simple. The agent's fee is a percentage of the final price and is paid by the seller. So the person walking you round the property, telling you the home is "well priced" and encouraging you to offer, is financially rewarded when you pay more, not less. That does not make them villains — but it does mean their price advice is not neutral.
| Selling / dual agent | Buyer's agent | |
|---|---|---|
| Paid by | Seller (fee inside the price) | You (flat fee or % of price) |
| Legal loyalty | The seller | You, the buyer |
| Incentive on price | Higher price = higher fee | Aligned with getting you a good deal |
| Sources properties | Its own and shared listings | Whole market, including off-market |
| Typical use | Standard purchases | Complex, remote or high-value buys |
A buyer's agent in Spain works only for you and is paid by you — so their advice on price and property is genuinely independent. That model is more common on the Costa del Sol's higher-value market than on the Costa Blanca, and it is worth considering if you are buying remotely, at the top of the market, or simply want someone whose loyalty is contractually yours. Either way, understanding how to negotiate the price yourself keeps you in control regardless of who introduced the property.
The reassuring news is that the strongest protections in a Spanish transaction do not come from the agent at all. They come from an independent legal chain designed to verify title, debts and legality before your money moves. Prioritise these:
Because registration and market structure differ by region, the right approach shifts slightly depending on where you buy. If you are still deciding, our comparison of the four coasts sets out lifestyle, price and access differences, and non-residents should read our non-resident buying guide before instructing anyone. Whichever coast you choose, the principle is constant: let the agent open doors and manage the process, but let your independent lawyer protect your money.
Normally no. On the Costa Blanca, Costa Cálida, Costa del Sol and Costa Almería the seller pays the agency commission (typically 3–6% plus IVA), and it is already built into the asking price. The exception is if you separately hire a dedicated buyer's agent, whom you pay directly.
Commission is a free agreement between the seller and the agency, so as a buyer you do not negotiate it — but you do negotiate the price, which is where the fee ultimately sits. Focus your energy there rather than on the commission itself.
Yes. There is no prohibition on one agency representing both sides, and it is very common because listings are shared across agencies. The safeguard is not banning it but hiring your own independent lawyer and, for complex purchases, considering a dedicated buyer's agent whose loyalty is contractually yours.
Not nationally — the profession was deregulated in 2000, so API registration is voluntary. However, Andalucía (Costa del Sol and Costa Almería) operates a mandatory agency register with insurance requirements, while the Comunidad Valenciana and Murcia do not. Always ask for insurance and, in Andalucía, the registration number.
Use an independent lawyer who does not act for the agent or seller, insist on a nota simple, complete before a Spanish notary, keep your deposit in a protected account, and for off-plan purchases ensure a bank guarantee covers your stage payments.
Not entirely. A selling or dual agent is paid a percentage of the final price by the seller, so they benefit from a higher price. Their market knowledge is valuable, but for a truly independent view on value, use a buyer's agent or lean on your lawyer and your own research.
