Finding an attractive property in Spain is often the easy part. The real questions begin when you are ready to buy.
Who checks that the property's legal status is in order? What happens before you pay a reservation deposit? Who keeps track of agreements with the seller, lawyer, bank and notary? And how do you avoid missing important steps as a Dutch buyer when the Spanish property buying process works differently from what you are used to?
This is where property buying support comes in. Casa de Bas assists Dutch buyers on the Costa Blanca and Costa del Sol, bringing property selection, viewings, legal coordination, financing and completion together into one organised buying process.
Through its property buying support service in Spain, Casa de Bas provides assistance from the initial search through to the handover of the keys.
Why Casa de Bas Is Not Just Another Estate Agency in Spain

Casa de Bas was founded following Fred and Carien de Bas's own experience of buying a property in the Alicante region.
During their purchase in Spain, they found that the assistance available did not meet the level of care and attention they were accustomed to in the Dutch property industry. Among the difficulties they encountered were limited expertise, unclear information and questions surrounding legal checks.
Rather than simply launching another property portal, Fred and Carien subsequently completed training in Alicante to become accredited estate agents in Spain and established a local network of Dutch-speaking professionals.
You can read more about their background on the About Casa de Bas page.
This background gives their service a clear purpose: the support is designed around the same questions and challenges Dutch buyers encounter when purchasing a property in Spain for the first time.
What Does a Dutch Buyer's Estate Agent in Spain Do for You?
Property buying support goes beyond sending property listings and arranging viewing appointments.
As part of the process, Casa de Bas helps with:
- Turning your property requirements and budget into a focused search
- Comparing regions and individual properties
- Arranging property viewings
- Identifying potential issues that require further investigation
- Involving the appropriate legal professional at the right time
- Coordinating financing questions with a financial adviser
- Keeping track of agreements, contracts and deadlines
- Coordinating the process through to notarial completion and the handover of the keys
The estate agent does not replace the lawyer, notary or financial adviser. The added value lies in organising the process and ensuring that each specialist becomes involved at the appropriate stage.
Who Is Responsible for What During Your Purchase?
| Party | Role | Examples |
|---|---|---|
| Casa de Bas | Coordination and property buying support | Property requirements, shortlisting, viewings, coordination, deadlines and completion |
| Lawyer | Independent legal due diligence | Checking ownership, charges, documentation, contracts and legal risks |
| Notary | Formal role in the public deed | Identifying the parties and authorising the public deed of sale |
| Financial Adviser | Financing | Assessing mortgage options, personal funds and lending conditions |
What Exactly Is the Secure Purchase Plan?
Casa de Bas calls its structured property buying support service the Secure Purchase Plan.
On its website, the plan is described as end-to-end assistance, with Casa de Bas providing structure and oversight while ensuring the right professionals are involved at the appropriate stages.
The publicly documented aspects of the service include:
- Initial guidance on requirements, regions and property types
- Property search and viewing support
- Coordination of the buying process
- Coordination of legal matters with a lawyer
- Coordination of financing questions with a financial adviser
- Involvement of the notary at completion
- Monitoring agreements, contracts and deadlines
- Support through to receiving the keys
How much does the Secure Purchase Plan cost? Casa de Bas does not currently publish a fixed fee on its website. During the no-obligation consultation, ask for a written explanation of the services provided, the fee and any additional third-party costs before committing.
See the current description of the Secure Purchase Plan and property buying support.
A Real Casa de Bas Customer Example
Casa de Bas has published a customer example on its website involving a buyer who chose a three-bedroom new-build apartment in Alicante.
According to the published account, the buyer felt that the property's layout and finishes made it seem as though the apartment had been designed specifically for them.
This example is relevant because it shows that buying support is not solely about preventing legal problems. Property type, layout, maintenance, energy consumption and intended long-term use also influence the final decision.
You can find the original customer example in Casa de Bas's article about the benefits of buying a new-build property in Spain.
Step 1: Start with a Clear Property Search
A carefully managed purchase does not begin by viewing twenty randomly selected properties.
Casa de Bas starts by considering how you intend to use the property and what you need from it. For example:
- Permanent residence, spending winters in Spain or holiday use
- Total purchase budget
- New build or resale
- Apartment, townhouse or villa
- Distance to the beach, airport and amenities
- Maintenance requirements
- Any plans to rent out the property
You can then compare regions more effectively.
Casa de Bas focuses on areas including the Northern Costa Blanca, Southern Costa Blanca and Costa del Sol.
Step 2: Compare Currently Available Properties

General market information is useful when beginning your search, but current property listings show what your budget can actually buy.
Through Casa de Bas, you can compare properties for sale in Spain.
If you are specifically interested in modern developments, you can also explore the current selection of new-build developments in Spain.
Step 3: Use Viewings to Identify Potential Risks
During a property viewing, you should look beyond the sales photographs.
Points worth discussing during the visit include:
- Location and accessibility
- Parking
- Orientation and sunlight
- Condition and maintenance
- Owners' community fees
- Visible extensions or alterations
- Surrounding noise levels
- New construction plans in the immediate area
A viewing can reveal matters that need further attention. Legal due diligence should then establish which of these issues have legal implications.
Step 4: Arrange Legal Checks Before Becoming Fully Committed
Casa de Bas explicitly states on its buying support page that it works with a Dutch-speaking professional network, including lawyers, financial advisers and notaries.
Depending on the transaction, the lawyer may check:
- Registered ownership
- Mortgages and other charges
- IBI and relevant local obligations
- Owners' community status
- Planning permissions and the legal status of alterations
- Purchase and reservation agreements
- New-build documentation and guarantees, where applicable
An important point about transparency: Casa de Bas does not currently publish the names or professional registration details of the lawyers and notaries involved on its public website. During your initial consultation, ask who will actually handle your case, what professional qualifications they hold and who formally represents your interests.
A Practical Casa de Bas Property Buying Checklist
The following checklist can help you establish whether your purchase is sufficiently prepared to move forward:
- Has the registered owner been verified?
- Have mortgages, attachments and other charges been investigated?
- Have IBI and relevant municipal records been checked?
- Has the owners' community position been reviewed, where applicable?
- Have alterations been compared with the registered property details?
- Have the relevant planning permissions been checked?
- Have you obtained your NIE or applied for it in good time?
- Is your financing sufficiently secure before you enter into a binding commitment?
- Has your legal adviser reviewed the contract?
- Do you know how much money must be available at each stage?
- Are the applicable taxes and professional costs clear?
- Have the practical arrangements after completion been planned?
Casa de Bas does not currently publish the percentage of purchase cases in which problems are identified during this stage. Including such a figure in this guide would therefore be inappropriate without verifiable internal customer data.
Step 5: Reservation Agreements and Contracts
Once you have found the right property, you may be asked to sign a reservation agreement or private purchase contract.
Before paying, check:
- How much you must pay
- Who receives the money
- Under which circumstances the payment is refundable
- Which legal conditions are still outstanding
- What deadlines apply
- Whether financing is included as a condition, if necessary
- What happens if either buyer or seller cannot proceed
Have the actual contract legally reviewed. Do not rely solely on being told that it is a "standard contract".
Step 6: Arrange Financing and Your NIE in Good Time
Casa de Bas states that it coordinates financing enquiries with a financial adviser from its Dutch-speaking professional network.
This is important because mortgage availability depends on your personal financial circumstances, the property, its valuation and the lender's conditions.
Foreign buyers also normally need an NIE for property purchases and related Spanish tax procedures. Arrange this early enough to prevent administrative delays immediately before completion.
Step 7: From Legal Approval to Receiving the Keys
Once legal checks have been completed, contractual conditions have been met, and payments and financing are ready, the final purchase can be prepared.
The public deed of sale is signed before a Spanish notary.
The next steps include:
- Registration of ownership
- Utility arrangements
- Property insurance
- Owners' community administration
- Local taxes and payments
- Safekeeping of purchase and tax documentation
New-Build Purchases Require Additional Support

New-build purchases involve different considerations from resale properties.
These include:
- Development documentation
- Payment schedule
- Protection of advance payments
- Technical specifications
- Completion conditions
- Documentation required before the property can be legally occupied
Compare current new-build developments in Spain before deciding which type of purchase best suits your needs.
Northern Costa Blanca, Southern Costa Blanca or Costa del Sol?

Casa de Bas focuses on three main coastal regions.
Northern Costa Blanca
If you are looking around Jávea, Moraira, Dénia, Altea or Calpe, start with the Northern Costa Blanca area guide.
Southern Costa Blanca
For areas such as Orihuela Costa, Guardamar del Segura and Pilar de la Horadada, use the Southern Costa Blanca area guide.
Costa del Sol
If you are considering Marbella, Estepona, Benahavís, Mijas or Fuengirola, begin with the Costa del Sol area guide.

- A Dutch-speaking network of lawyers, financial advisers and notaries
