The complete step-by-step guide to purchasing off-plan and new build property in Costa Blanca. From NIE numbers to notary completion — everything you need to know.

📖 12 min readUpdated February 2026Expert Verified

Buying new build property in Spain offers significant advantages over resale: modern construction standards, energy efficiency, builder warranties, and the ability to customize finishes. This guide walks you through the entire process from first viewing to collecting your keys.

1Property Search & Selection

Start by defining your requirements: location, property type, budget, and timeline. For new builds, you'll typically choose between:

  • Off-plan: Purchase before construction completes (often 12-24 months). Lower entry price, more customization options.
  • Under construction: Building has started, completion within 6-12 months.
  • Key-ready: Completed and ready to move in. What you see is what you get.

We recommend visiting Costa Blanca to see developments in person. Our team offers viewing trips and video tours for overseas buyers.

2Reservation Agreement

Once you've found your property, you'll sign a reservation agreement and pay a deposit to take it off the market. This is typically:

  • €3,000 - €10,000 depending on property value
  • Usually held for 30-60 days while you arrange finances and paperwork
  • Normally deducted from the purchase price

Important:

The reservation deposit may be non-refundable if you withdraw without valid reason. Read the terms carefully before signing.

3Getting Your NIE Number

The NIE (Número de Identificación de Extranjero) is your Spanish tax identification number. You cannot buy property, open a bank account, or connect utilities without it.

You can apply:

  • In Spain: At the Foreigners Office (Oficina de Extranjería) or National Police station
  • From abroad: At the Spanish Embassy or Consulate in your country

Processing typically takes 1-4 weeks. Many lawyers can handle this for you via power of attorney.

4Opening a Spanish Bank Account

You'll need a Spanish bank account for:

  • Paying the purchase price and taxes
  • Setting up direct debits for utilities and community fees
  • Mortgage payments (if applicable)

Major banks like Sabadell, CaixaBank, and Santander have experience with international buyers. You'll need your NIE, passport, and proof of income/address.

5Private Purchase Contract

The Contrato de Compraventa is the binding purchase contract between you and the developer. At signing, you'll pay:

  • 20-30% of the purchase price (minus the reservation deposit)

The contract should include:

  • Full property specifications and plans
  • Payment schedule
  • Expected completion date
  • Penalty clauses for delays
  • Bank guarantee details (mandatory in Spain)

Bank Guarantee Protection

Spanish law requires developers to provide a bank guarantee or insurance for all stage payments. If the developer fails to complete the property, you're entitled to a full refund of payments made.

6Stage Payments During Construction

For off-plan properties, you'll make payments linked to construction milestones. A typical schedule:

StageTypical %
Reservation€3,000-10,000
Contract signing20-30%
During construction20-30%
Completion40-50%

Keep all payment receipts and bank guarantee certificates safely filed.

7Snagging Inspection

Before completion, you (or a professional snagging company) should inspect the property and compile a snagging list of any defects:

  • Paintwork and finishes
  • Doors, windows, and locks
  • Plumbing and drainage
  • Electrical installations
  • Tiling and flooring
  • Air conditioning and appliances

The developer must fix snagging issues before completion or agree to a retention from the final payment.

8Completion at the Notary

The final step takes place at a Spanish notary where you'll:

  • Sign the Escritura (title deed)
  • Pay the final balance
  • Pay IVA (VAT) and Stamp Duty
  • Receive the keys!

You can attend in person or grant Power of Attorney to your lawyer. After signing, your lawyer registers the property at the Land Registry.

Frequently Asked Questions

How long does it take to buy property in Spain?

Do I need a lawyer to buy property in Spain?
While not legally required, we strongly recommend using an independent lawyer. They'll check contracts, verify the property is legally sound, handle NIE applications, and represent you at the notary if needed. Expect to pay 1-1.5% of the purchase price.
Can I buy property in Spain without an NIE number?
No. The NIE (Número de Identificación de Extranjero) is mandatory for all property purchases in Spain. You'll also need it to open a bank account, sign utility contracts, and pay taxes. Apply early as it can take 1-4 weeks.
What deposit do I need to buy property in Spain?
You'll typically pay €3,000-€10,000 as a reservation deposit, then 20-30% at contract signing. For off-plan properties, additional stage payments of 20-30% are made during construction, with 40-50% due at completion.
Is my deposit protected when buying off-plan in Spain?
Yes. Spanish law (Law 20/2015) requires developers to provide bank guarantees or insurance for all payments made before completion. If the developer fails to deliver, you're entitled to a full refund with interest.
What taxes do I pay when buying new build property in Spain?
New builds attract 10% IVA (VAT) plus approximately 1.5% stamp duty (AJD). Total additional costs including taxes, notary, registry, and legal fees are typically 13-14% of the purchase price.

A snagging inspection identifies defects in a new build property before you complete the purchase. Issues like paint imperfections, faulty fixtures, or incomplete finishes are documented and must be fixed by the developer before completion.
