New build developers must provide complete pricing transparency under Royal Decree 515/1989, showing all costs upfront. For a €400,000 apartment, buyers face €44,800 in additional taxes and fees. Bank guarantees covering 100% of advance payments are mandatory, with fines reaching €600,000 for pricing violations.

Spanish property advertising law operates under Royal Decree 515/1989 and the General Law for Consumer and User Protection (LGDCU), which mandate complete price transparency for new construction. Developers must display the total acquisition cost including the base property price, 10% IVA (value-added tax), and 1.2% AJD stamp duty on all marketing materials. In Fuengirola, a typical €400,000 new build apartment requires an additional €44,800 in taxes (€40,000 IVA + €4,800 AJD), bringing the total to €444,800 before notary fees of approximately €6,000-€10,000.

The Consumer Protection Act specifically prohibits 'drip pricing' where costs are revealed incrementally during the sales process. All brochures, websites, and sales contracts must show either the complete final price or a detailed breakdown including utility connections (typically €400-€800 for electricity), community setup fees, and legal costs. Promotional discounts advertised must remain valid for the stated period and cannot be withdrawn once a reservation is made with a deposit.

Financial Protection Requirements for Buyers

Law 57/1968 Article 1 requires developers to secure bank guarantees or insurance policies covering 100% of any advance payments for off-plan properties. This means if you pay €50,000 as a deposit on an under-construction property in Mijas, the developer must have €50,000 guaranteed by a Spanish bank. The guarantee certificate must be provided within 30 days of any payment, and failure to provide this document makes the contract voidable at the buyer's discretion.

Additionally, developers cannot request more than 20% of the property price as advance payments before construction completion, though many Costa del Sol projects operate with stage payments: typically 10% on reservation, 10% on foundation completion, and the remainder on delivery. For a €500,000 penthouse in Estepona, maximum advance payments would be €100,000, all covered by mandatory bank guarantees.

Costa del Sol Market Context and Compliance

The Costa del Sol's international buyer market has driven enhanced enforcement of pricing transparency laws since 2019. The Junta de Andalucía now conducts regular inspections of developer marketing materials, with fines ranging from €6,000 to €600,000 for pricing violations. In Marbella's Golden Mile area, where land costs €400-€800 per square meter, the total development cost including land acquisition, construction (€1,200-€2,500/m²), and legal compliance often creates a 15-20% margin between advertised price and true market cost.

New build properties typically command a 10-25% premium over comparable resales due to modern specifications and warranty coverage. However, this scarcity premium must be clearly justified in marketing materials. Developers cannot advertise 'starting from' prices unless at least 10% of units are actually available at that price point, a requirement frequently violated in premium developments along the coast.

Next Steps for Informed Property Investment

Before committing to any new build purchase, request the complete price breakdown in writing, including all taxes, fees, and optional extras like parking spaces (typically €15,000-€35,000) or storage rooms (€8,000-€18,000). Verify the developer's bank guarantee documentation and ensure your solicitor reviews the purchase contract against advertised prices. Your lawyer should also confirm the developer's building licence validity and check for any municipal planning restrictions that could affect completion.
