Many believe that access to development projects is limited to institutional investors. At Avanta Development, our goal is to make high-quality real estate investments more accessible.
Our entry threshold approach:
• Direct participation: On average, the minimum entry level for our private investment pools starts from €200,000–€300,000. This allows investors to enter at the pre-construction stage (land preparation and licensing phase).
• What you receive: With this investment, you become a co-investor in a project with forecasted ROI, ROE, and IRR indicators.
Important: We operate with full transparency. The investment amount is fixed in the contract, and the exit strategy is defined before any land works begin.
Development investments are long-term strategies with strong value creation potential. Our target returns significantly exceed traditional rental yields due to the added value created through development.
We focus on two key financial indicators:
1. ROI (Return on Investment) — 25–35%
This represents the total net profit on your invested capital over the entire project cycle.
• Example: With a €300,000 investment, your projected net profit upon completion would range between €75,000 and €105,000.
• Source of profit: The difference between total development cost (including land acquisition and taxes) and the market value of the completed property in high-demand locations.
2. IRR (Internal Rate of Return) — 10–18% annually
This reflects the annualized efficiency of your capital, taking time into account.
• Project timeline: Our standard project cycle ranges from 18 to 36 months. This includes design, municipal licensing, construction, and final sales.
• Performance: An IRR of 10–18% per year in euros is considered strong for the European real estate market, combining high profitability with the security of a tangible asset.
We operate fully within Spanish legal standards, where quality and legal compliance are top priorities.
• 18 months — accelerated cycle for projects with existing licenses or deep renovation.
• 36 months — full-cycle construction of exclusive villas or residential complexes from scratch, including architectural planning and landscaping.
Summary: A 36-month cycle allows us to maximize project quality, directly influencing final market value and enabling ROI up to 35%.
• Location: We acquire land in supply-constrained areas (Estepona, Marbella, Benahavís), where demand consistently exceeds supply.
• Process optimization: Our in-house construction management expertise reduces costs and prevents delays.
• Early-stage entry: Investors join during the land preparation stage, ensuring maximum capital appreciation.
Conclusion: Investing with Avanta Development means participating in a transparent financial model where high returns (ROI up to 35%) are backed by a real asset in one of the world’s most sought-after regions.
Investing abroad raises understandable concerns about security. At Avanta Development, we strictly comply with Spanish law, which provides multi-layered investor protection.
Under Law 20/2015, developers of multi-unit projects must guarantee the refund of all advance payments.
• If the project is not completed on time or the developer faces financial difficulties, the bank is legally obliged to return the invested funds plus statutory interest.
• Individual guarantees are issued to each investor once the building license is granted.
Investor funds are transferred to a dedicated project account.
• The bank strictly controls expenditures, ensuring funds are used exclusively for project-related expenses (materials, labor, taxes).
• This eliminates the risk of misuse.
Spanish law requires a 10-year structural insurance policy:
• 1 year — finishing defects
• 3 years — habitability defects
• 10 years — structural integrity (foundation, structure)
All transactions are executed before a Spanish notary, ensuring legality and transparency. Ownership rights are recorded in the public Property Registry (Registro de la Propiedad), preventing double sales or legal irregularities.
Our principle: We work exclusively with established banks such as Santander, CaixaBank, and BBVA, and engage independent legal advisors for each transaction. Your capital is protected not only by our reputation but by European legal frameworks.
Costa del Sol has evolved far beyond a seasonal resort destination. Today, it represents a self-sustaining international economic hub.
Unlike Madrid or Barcelona, which rely more heavily on domestic demand, Costa del Sol is driven by international buyers from the UK, Germany, Scandinavia, the US, and the UAE.
• This diversifies demand and reduces exposure to localized economic downturns.
The region offers world-class infrastructure for expatriates:
• International schools
• English-speaking medical facilities
• Golf clubs and marinas such as Puerto Banús
Investors are not purchasing property alone, but access to a global lifestyle ecosystem.
In areas such as Marbella, Estepona, and Benahavís, development land is physically constrained by sea and mountains.
• Scarcity ensures long-term price growth and strong capital appreciation.
Over 300 sunny days per year support year-round demand, attracting digital nomads and international executives.
Avanta Development conclusion: While Madrid and Barcelona represent investment in national infrastructure, Costa del Sol represents investment in global demand and an exclusive lifestyle that cannot be replicated at scale.
Development is a multi-stage process requiring legal and technical expertise. Our full cycle typically lasts 18–36 months.
We conduct full Due Diligence:
• Urban planning compliance
• Absence of encumbrances
• Geological analysis
Result: Acquisition of land with strong appreciation potential.
Architectural development aligned with sustainability and energy-efficiency standards.
Application for the main construction license (Obra Mayor) through municipal authorities.
Execution with strict technical supervision and trusted contractors.
Investors receive regular progress reports, photos, and updates.
Sales campaigns begin during pre-construction.
Goal: Sell the majority of units before completion to secure profitability and reduce risk.
Obtaining the First Occupancy License (LPO — Licencia de Primera Ocupación).
Final notarized sales transactions.
Investors receive profit distribution (ROI), and buyers receive property keys.
No. Spanish residency is not required to invest in real estate or development projects.
Spain is fully open to foreign capital. You can live anywhere in the world and legally own assets on the Costa del Sol.
What you will need:
NIE (Número de Identificación de Extranjero) — Foreigner identification number required for financial transactions. It does not grant residency. We assist investors in obtaining it.
Spanish bank account — Required for transactions and tax payments.
Summary: You can invest remotely while we handle full operational management. Legal protection is ensured through your NIE registration and official property registration.
