A Costa del Sol viewing can make the decision feel wonderfully simple: the terrace has the right light, the beach is close, and you can picture the first holiday already. Reserving it is the moment to slow down. To reserve Spanish property safely, treat the reservation payment as the start of a legal and financial process, not merely proof that you are serious.
There is no single standard reservation agreement used across Spain. The amount paid, where it is held, what checks take place and whether it is refundable can all vary. That is why a well-run reservation should give you time to investigate the property properly, with clear written terms before money changes hands.
What a reservation payment should achieve
A reservation payment normally takes a property off the market for an agreed period while the buyer’s independent lawyer carries out initial checks and prepares for the next contract. On the Costa del Sol, this is often a relatively modest sum compared with the purchase price, but it is still money that needs protecting.
The agreement should identify the buyer and seller, the exact property, the agreed purchase price, the reservation amount and the deadline for progressing to the private purchase contract. It should also say where the funds will be held and precisely when they are returned, retained or credited towards the price at completion.
Do not rely on a verbal assurance that the property is “reserved”. If another buyer appears, the written agreement is what establishes the position. Equally, a reservation document should not pressure you into completing regardless of what your legal checks uncover.
Reserve Spanish property safely with the right people involved
Your estate agent can coordinate the offer, communicate with the seller and keep the transaction moving, but your lawyer should be independent and chosen by you. This is particularly important for overseas buyers who may be signing documents from the UK and cannot visit every office in person.
Ask for the name and details of the seller, the proposed reservation agreement and payment instructions before transferring funds. A genuine transaction should withstand sensible questions. You should understand who is receiving the money, in what capacity, and how it will be accounted for.
Where possible, use a properly regulated client account or an arrangement confirmed in writing by your lawyer. Avoid sending a deposit to an unfamiliar personal bank account. Be alert to last-minute emails claiming bank details have changed: payment fraud often relies on an urgent message arriving just before a transfer. Confirm any instructions using a known telephone number, not the number printed in the unexpected email.
If you are buying with a mortgage, tell your lender or broker about the intended timetable before reserving. Finance is not always available on the same timescale as a seller’s preferred completion date, and a valuation may affect the amount a lender will offer. Cash buyers should also allow time for money transfers, source-of-funds checks and exchange-rate planning rather than assuming funds can be moved overnight.
Check the property before the commitment becomes expensive
A reservation period is valuable because it creates room for due diligence. Your lawyer will normally obtain and review the key legal documents, but it helps to know what they are looking for.
They should confirm that the seller has legal title, that the property description matches what is being sold and that there are no charges, embargoes or rights affecting the purchase that have not been dealt with. For a flat, townhouse or home within a community, they should also check community fees, any outstanding payments and relevant rules. A beautiful rooftop terrace or holiday-rental potential may matter less if the community statutes limit how the property can be used.
Planning and occupancy status deserve close attention, particularly with older villas, rural homes, extensions and properties that have been altered over time. Your lawyer should assess the paperwork that applies to the particular property, including whether required licences or certificates are in place. Never assume that a swimming pool, enclosed terrace or extra bedroom is automatically legal because it has existed for years.
Practical checks matter too. View the home again if possible, ideally at a different time of day. Test shutters, air conditioning, appliances, water pressure and parking access. Ask what is included in the sale, from furniture to storage rooms and parking spaces, and ensure it is recorded. For a property intended for lettings, investigate demand, licensing requirements and the likely running costs before relying on projected income.
Understand the move from reservation to arras contract
The reservation agreement is often followed by a private contract, commonly referred to as an arras contract. This is usually a more significant commitment, with a larger deposit and stronger consequences if either party withdraws. It is not a document to sign simply because the deadline has arrived.
A commonly used form of arras provides that the buyer may lose the deposit if they pull out, while the seller may have to return double the amount if they withdraw. However, the wording matters. Different contracts create different obligations, and the consequences are not identical in every case.
Before signing, make sure the contract states the full price, deposit paid, completion date, items included, any agreed repairs and the arrangements for vacant possession. If the purchase depends on mortgage approval, a sale of another property or a specific legal issue being resolved, that needs to be addressed expressly. Assumptions are where avoidable disputes begin.
It can be tempting to accept a short deadline to secure a sought-after Marbella or Estepona property. Sometimes that is reasonable, especially where documents are already in order and funds are ready. But speed should not replace checks. A seller who wants a quick, clean transaction should also understand why an international buyer needs their lawyer to verify the essentials.
Budget beyond the headline price
A safe reservation is also one you can afford to complete. In addition to the agreed price, buyers need to budget for taxes, notary and Land Registry costs, legal fees and any mortgage-related costs. The exact total depends on whether the property is a resale or new build, its price and the structure of the purchase.
You should also look beyond completion. Community charges, IBI local property tax, rubbish collection, insurance, utilities, maintenance and non-resident tax can all form part of ownership. For a lock-up-and-leave holiday home, keyholding and regular inspections may be a worthwhile safeguard. For an investment property, factor in furnishing, management, periods without tenants and the cost of meeting rental rules.
Currency movement is another consideration for buyers bringing sterling into euros. A favourable offer price can become less favourable if the exchange rate moves sharply before completion. Discuss the timing of transfers early and keep a clear record of the source of every payment, as Spanish banks and professionals may need supporting evidence for anti-money-laundering checks.
Questions worth asking before you transfer
Before signing a reservation agreement, you should be able to answer a few straightforward questions. What is the exact deadline? Is the fee refundable if legal due diligence reveals a material problem? Who holds the money? What happens if the seller withdraws? What conditions must be met before you sign the next contract?
Also ask whether the property is currently occupied, let to tenants or subject to an existing holiday booking. Clarify the handover date, keys, utility readings and any furniture inventory. These details may sound minor while you are focused on securing the home, but they can make a major difference to your first weeks as an owner.
A good agent will welcome these questions and help keep expectations clear between all parties. At Best in Spain, buyers can combine local market guidance with support through the practical stages of purchasing, from identifying the right area and property to planning for ownership after completion.
The right home under the sun should feel exciting, not rushed. Reserve when the offer is clear, the paperwork is in place, your independent lawyer has a defined window to investigate and the funds are protected by written terms. That approach gives you the confidence to look forward to the keys, rather than worry about the deposit.
