Off-Plan Mortgage on the Costa del Sol: Financing a New-Build Property
The Costa del Sol offers a wide range of new-build developments across Málaga, Marbella, Estepona, Fuengirola, Benalmádena and Mijas.
Buying off-plan allows you to secure a property before construction is completed, often with the opportunity to choose finishes or layouts depending on the stage of the development. However, the financing process is different from purchasing a resale property.
Arranging an off-plan mortgage on the Costa del Sol requires careful coordination between the developer’s payment schedule, construction progress, property valuation and final mortgage approval. From our experience working with international buyers, understanding this timeline from the beginning is key to avoiding surprises later in the process.
What does buying off-plan mean?
Buying off-plan means signing a purchase contract while the property is still under construction or, in some cases, before building work has started.
The buyer usually makes several staged payments throughout the development period. The remaining balance is paid upon completion, when the property is delivered and the title deed is signed.
The exact structure depends on the developer and the contract terms, so it should always be reviewed carefully before committing to any payment.
When should you apply for the mortgage?
An initial mortgage assessment can be carried out before reserving the property. This helps determine whether the purchase price is realistic based on the buyer’s income, savings and overall financial profile.
However, final mortgage approval is usually granted closer to completion, once the property can be officially valued and the lender has all required documentation.
For this reason, the buyer’s financial position must remain stable throughout the construction period. Changes in income, employment status or new debt commitments may affect the final mortgage offer.
In many cases, working with a mortgage broker early in the process helps ensure the financing remains aligned with the development timeline.
Payments during construction
New-build developments typically follow a staged payment plan. Although the exact terms vary by project, the usual structure may include:
Reservation deposit
The initial payment used to secure the property and begin the purchase process.
Private purchase contract
A further payment is normally made when the private purchase agreement is signed.
Instalments during construction
Additional staged payments may be required according to the schedule agreed with the developer.
Final payment and completion
The outstanding balance is paid when the property is completed and the title deed is signed.
Buyers should ensure these payments are manageable without using funds reserved for taxes, legal fees or unexpected costs.
Maintaining a financial buffer is especially important when completion is scheduled several months or years in the future.
Protection of advance payments
Spanish law provides protections for certain advance payments made during the construction phase, provided legal requirements are met by the developer.
Buyers should always confirm:
- The bank account where funds will be held.
- The existence of a bank guarantee or insurance policy.
- Refund terms and conditions.
- The expected completion date.
- Procedures in case of construction delays.
Given the legal complexity of off-plan purchases, independent legal advice from a Spanish property lawyer is strongly recommended.
Valuation of a new-build property
A mortgage valuation is required by the lender to assess the property’s market value and lending risk. In Spain, valuations must be carried out by approved valuation companies.
The maximum loan amount is based on the lower of the purchase price or the valuation result.
If the valuation comes in below the agreed purchase price, the buyer may need to contribute additional funds.
For this reason, it is not advisable to structure the purchase assuming the maximum loan-to-value will always be available.
Taking over the developer’s mortgage
Some developments offer the option to take over the developer’s existing mortgage.
While this can appear convenient, it should always be compared carefully with alternative mortgage offers.
Key factors to review include:
- Interest rate.
- Mortgage term.
- Fees and commissions.
- Linked products.
- Transfer costs.
- Alternative offers from other banks.
In many cases, a separate mortgage arranged independently may provide more flexibility.
Off-plan purchases by non-residents
A significant proportion of off-plan buyers on the Costa del Sol are non-residents from the UK, Europe, the United States and the Middle East.
For these buyers, financing can reach up to 70% of the property value, subject to lender approval and final valuation.
Lenders will typically require documentation relating to income, savings, liabilities and tax residency.
At New Property Mortgages, we specialise in international cases and coordinate the entire process remotely, from initial assessment through to completion.

Set aside funds for taxes and purchase costs.
Have the contract reviewed by an independent lawyer.
