The moment you put your home on the market the same question appears: do I give the instruction to one estate agency in Alicante, or to four so the best one wins? Intuition says that the more hands pushing, the sooner it sells. The market works rather differently, and it is worth understanding why before signing anything — not because one option is morally better than the other, but because each produces very different effects on the price you finally bank.
How each model works
Under a sole agency you instruct a single professional for an agreed period. That professional absorbs the cost of the photography, the floor plan, the video, the paid advertising and the viewing hours knowing that if the property sells, they get paid. Under multi-agency — sometimes called an open or simple instruction — you sign with several agencies at once and the fee goes to whoever closes the deal. The others get nothing, whatever they invested.
That single detail explains almost everything that follows. If an agency knows it has a 25% chance of being paid, its rational investment in your property falls by the same proportion: quick photos, a standard listing, no campaigns and a hurry to turn any viewing into a low offer. It is not bad faith, it is arithmetic.
The problem with a duplicated listing on the portals
This is the effect that costs the most and that sellers least see coming. When four agencies list your property, a buyer searching a portal finds the same home four times, with four sets of photos, four descriptions and — almost always — four prices that do not match. Three things happen immediately:
- The property gets stale. It appears everywhere, looks as if it has been on the market for ages and as if nobody wants it.
- The reference price becomes the lowest one. If one agency lists at €295,000 and another at €279,000, the buyer negotiates down from €279,000. Your real asking price is the lowest one published, not the one you chose.
- You lose control of the story. Nobody can properly explain the kitchen refurbishment, the aspect or the levy already paid if every agency tells a different version.
With the Alicante market at record levels — an average of €2,721/m² in the city in August 2026 according to idealista, with areas at €3,859/m² — giving away 3% to 5% of the price because of a presentation problem is an expensive luxury.
What an estate agency in Alicante must give you for sole agency to be worth it
Sole agency is not a favour you do anyone: it is a contract in which you give something up and should receive something in return, in writing. If it is asked of you without any of the following on the table, the right answer is no:
- A valuation with real, dated comparables from your area, not a figure designed to win the instruction.
- Professional photography, a dimensioned floor plan and video or a virtual tour, at the agency's expense.
- A written publication plan: portals, positioning, paid campaigns and the date everything will be live.
- Enquiry filtering and attendance at every viewing — never keys handed to third parties.
- Paperwork resolved before any deposit contract: registry extract, energy certificate, building inspection, community debts.
- Regular reporting covering listing views, enquiries, physical viewings, feedback and offers.
- Service in the buyer's language: in the province of Alicante 44.65% of purchases are signed by a foreign buyer.
Side by side: sole agency versus multi-agency
| Aspect | Sole agency | Multi-agency |
|---|---|---|
| Point of contact | One, accountable for everything | Several, nobody accountable |
| Marketing investment | High: the agency is paid if it sells | Low: the chance of payment is split |
| Published price | One, consistent | Several; the lowest one rules |
| Buyer perception | A well-presented property | A repeated, «difficult» property |
| Fees | Agreed with a single agency | Paid to whoever closes |
| Control of the process | With the owner and their agent | Diluted |
| Main risk | Choosing the wrong agent | Wearing out the property and the price |
Term, exit and the right of withdrawal
The document that governs all this is the instruction agreement or instruction note, and it must set out at minimum the asking price, the fee and how it is calculated, the term, whether it is sole or shared, what happens if you sell privately, and when the right to be paid arises. Typical terms run from three to six months, with tacit or express renewal; some sole agency agreements are signed for shorter periods of two to four months, particularly when the asking price is above market and a review is expected.
On exiting, read two clauses carefully: the notice period and the penalty. And bear in mind a right many owners do not know about: if you signed the agreement away from the agency's premises — at home, in a café, remotely — you are a consumer and you have 14 calendar days to withdraw without giving a reason, under Spanish consumer protection rules. The agency is obliged to inform you of that right in writing; if it did not, the period is extended.
What the data does and does not say
Let us be honest: there is no independent, published study in Spain rigorously measuring how much higher or faster sole agency sells compared with multi-agency. Almost every figure in circulation is published by an interested party, one way or the other. What is verifiable is the rest: that fees are unregulated, that the reference price a buyer sees is the lowest one published, and that an agency's marketing investment is proportional to its chance of being paid. That is enough to decide without having to believe anyone's percentage.
In our experience the problem is rarely the model and almost always the asking price: a correctly valued property sells under either arrangement; a badly valued one sells under neither, it just takes longer to find out. We set out the real timings here: how long it takes to sell a home in Alicante and how to sell a flat quickly without underselling it.
At VITALITY we work on a sole agency basis only, which is why we carry the full cost of bringing your property to market. You can see how we do it on our selling page, or speak directly to this estate agency in Alicante before you sign anything with anyone.
Frequently asked questions
Do I have to sign a sole agency agreement to sell a flat?
No. You can instruct several agencies on a multi-agency basis or sell privately. Sole agency is a commercial decision, not a legal obligation, and it must be set out expressly in the instruction agreement together with the term and the fee.
How long does a sole agency agreement last?
In Spain three to six months is typical, with tacit or express renewal depending on what is agreed. More important than the length is what the agency commits to doing within that period and how often it reports back on viewings, enquiries and offers.
Can I exit a sole agency agreement early?
It depends on what was agreed: some contracts require notice and others impose a penalty. In addition, if you signed the instruction note away from the agency premises, for example at home, you have 14 calendar days to withdraw as a consumer and the agency must inform you of that right.
Does a property sell faster with several agencies?
Not necessarily. More agencies does not mean more buyers: the portals are the same and the buyer ends up seeing the same property repeated. What does change is the message, because a duplicated listing at different prices invites a buyer to negotiate downwards before the first viewing.
