Buying new-build property in Spain: a complete step-by-step guide

Buying new-build property in Spain is a structured process with clear legal protections, but it rewards buyers who understand each step before they sign anything. The paperwork, taxes, and timelines differ significantly from what most northern Europeans are used to at home, both for off-plan units bought from architectural drawings and for completed obra nueva homes. This guide covers every stage from obtaining your NIE to collecting your keys.

Getting your NIE before anything else

Your NIE, or Número de Identificación de Extranjero, is the tax-identification number Spain requires of all foreign nationals involved in a property transaction. Without it you cannot sign a purchase contract, open a Spanish bank account for the transfer, or register as the owner. Apply at a Spanish consulate in your home country or at a Policía Nacional office in Spain. Processing times vary, so apply as early as possible, ideally before you visit show homes or make any offer.

Appointing an independent abogado

Hiring your own Spanish property lawyer is the single most consequential step in the process. The developer's legal team works for the developer, not for you. Your abogado carries out a series of checks before you commit any money: confirming the developer holds a valid licencia de obras (building permit), ordering a nota simple from the Registro de la Propiedad to verify ownership and confirm the plot is free of encumbrances, reviewing the contrato de compraventa in detail, and checking that a seguro decenal (ten-year structural warranty) is in place. Independent abogado fees typically run around 1% of the purchase price plus VAT, which is modest relative to the protection they provide. veritySpain's project database records which developments have clean legal status, but always confirm with your own counsel.

The reservation deposit

Once you have chosen a property, the first financial commitment is the reservation deposit, which takes the unit off the market. Typical amounts run from roughly €3,000 to €10,000, though this varies by developer and property price. Pay this only when you are confident about proceeding, as conditions for refund differ between developers. Your abogado should review the reservation document before you transfer any funds.

The private purchase contract and stage payments

The main pre-completion agreement, called the contrato de compraventa privado, is signed after due diligence is complete. On signing, buyers typically pay 10% to 20% of the total price, with additional stage payments tied to construction milestones such as the structure topping out or internal fit-out reaching completion. These payment schedules are written into the contract, so you will know in advance when each tranche is due and what triggers it.

Bank guarantees protecting your off-plan payments

Any money you pay before completion on an off-plan property must be protected by an aval bancario, a bank guarantee issued by a financial institution guaranteeing repayment if the developer fails to deliver the property or obtain the first-occupation licence. This requirement derives from Spanish law, reinforced by Ley 20/2015, and applies to stage payments taken during construction. Notarios de España and consumer bodies advise buyers to verify that the guarantee covers their specific payments and that the issuing bank will honour a claim. Ask your abogado to confirm the guarantee document before each stage transfer.

Taxes and purchase costs

New-build property in Spain is subject to IVA at 10%, levied on the purchase price and payable at completion. Agencia Tributaria is the authority responsible for VAT collection, and your notary will confirm the breakdown at signing. On top of IVA, buyers pay Actos Jurídicos Documentados (AJD), the stamp duty on new-build transfers. The AJD rate is set by each autonomous community and typically falls in the range of 1% to 1.5%, though the exact figure for your region should be confirmed with your abogado. Adding notary fees, land registry fees, and legal costs, total acquisition costs on a new-build typically run to around 12% to 14% above the agreed purchase price. Budget for this from the outset rather than treating it as a surprise at completion.

Financing with a non-resident mortgage

Buyers who need a Spanish mortgage should approach lenders early, as valuation and approval processes take time and can influence your overall timeline. Banco de España guidance indicates that Spanish banks generally cap non-resident mortgages at around 60% to 70% of the property's appraised value, meaning you will need a meaningful deposit in place. Interest rates, arrangement fees, and required insurance products vary between lenders. Some buyers arrange financing in their home country and transfer the funds directly, which avoids the Spanish mortgage process but requires careful currency planning.

Completion at the notaría and registration

Completion takes place before a Spanish notario, a public official who verifies the identity of all parties, confirms the legality of the transaction, and reads the deed aloud. The buyer pays the outstanding balance, taxes are settled, and the escritura pública (public deed of sale) is signed. Immediately after completion your abogado submits the deed to the Registro de la Propiedad for registration, which formally records you as the legal owner and protects your title against subsequent claims. Request confirmation once registration is complete, as the process can take several weeks.

Buying with verified information

The Spanish new-build purchase process is well-regulated and, when followed correctly, carries strong protections for the buyer. The bank guarantee on stage payments, the seguro decenal structural warranty, and the notarial completion system all exist to reduce risk. What remains your responsibility is choosing the right professionals and verifying the legal status of the development independently.
