Nieuwbouw vs. herverkoop in Marbella: wat is de betere investering?

In 2026, new-build stock on the Costa del Sol carries a premium of approximately 15–25% per square metre over comparable resale stock in the same area. The exact premium varies: in Estepona, where new-build supply is abundant, the premium is closer to 15%; on the Golden Mile, where new-build supply is almost non-existent, it exceeds 30%. For a concrete example: a 200 m² apartment in a quality Estepona development costs approximately €700K–900K new versus €550–750K resale. On the Golden Mile, a similar apartment costs €1.6–2.4M new versus €1.1–1.6M resale.

However, the headline price per square metre comparison is incomplete. A resale property priced 20% below a new build often requires €50,000–200,000 in renovation to bring it to a comparable specification (new kitchen, updated bathrooms, energy-efficient windows, modern electrics). When you add renovation costs to the resale price, the real premium for new build drops to approximately 5–15%, and the renovation carries its own risks, delays, and stress.

This is the single clearest difference between new-build and resale purchases in Andalucía. Resale attracts Transfer Tax (ITP) at a flat 7%. New builds attract IVA (VAT) at 10% plus AJD (Stamp Duty) at 1.2%, totalling 11.2%. On a €1M property, this is a €42,000 difference: €70,000 ITP versus €112,000 IVA+AJD. This is real money and must be factored into any comparison.

The only scenario where new-build tax is lower than resale is if you are buying a commercial property or a plot of land (both attract different rates), or if you are a developer buying to resell (IVA can be reclaimed as input tax). For private buyers purchasing a home to live in or rent out, the new-build tax premium of 4.2 percentage points is a consistent and unavoidable cost.

The build quality of Costa del Sol new developments has improved dramatically. Developments built during the 2002–2008 boom were often constructed quickly with cost-cutting on insulation, waterproofing, and structural details. Many resale properties from that era have known issues: thermal bridging, single-glazed or early double-glazed windows, poor sound insulation between units, limited electrical capacity for modern appliance loads, and energy ratings of E or F.

Today’s new builds are required to meet current Technical Building Code (Código Técnico de Edificación, CTE) standards, which mandate higher insulation, triple-glazed windows in many orientations, heat-recovery ventilation in some configurations, and energy ratings of A or B. Practical benefits include: 30–50% lower electricity bills compared to a 2000s-era apartment of the same size, better sound insulation from neighbours, home automation pre-wiring, and underfloor heating as standard in most luxury developments. These are genuine daily quality-of-life improvements that are expensive to retrofit into an older building.

In the first 3–5 years after completion, new builds on the Costa del Sol have historically appreciated faster than resale stock in the same area. This is partly because off-plan buyers purchase at today’s price and take delivery 2–3 years later, by which time the market has often moved up. It is also because new builds attract a wider buyer pool on resale, more international buyers prefer modern specifications and are willing to pay a premium for turnkey condition.

Beyond the 5-year mark, the appreciation rates converge and the key driver becomes location rather than newness. A well-maintained resale villa in the Golden Mile will outperform a new-build apartment in a less prime area of Estepona over a 10-year period. Our recommendation: if you are buying for 3–5 year capital growth, new build in a high-demand area (Estepona, East Marbella) is the strongest play. If you are buying for 10+ years, location trumps everything else.

For buyers purchasing as an investment, new-build properties command a 15–20% premium on short-let rental rates compared to older stock of the same size in the same area. This is driven by guest expectations on platforms like Airbnb and Booking.com, where modern finishes, open-plan layouts, and high-quality photos directly translate to higher nightly rates and better occupancy. A new-build 2-bedroom apartment in Estepona might achieve €120–160 per night in summer versus €90–120 for a dated 2-bedroom in the same street.

On a gross yield basis, however, the higher purchase price of new builds largely offsets the higher rental income. A new-build 2-bedroom apartment at €600K generating €35,000 gross annual rental produces a 5.8% gross yield. An equivalent resale at €450K generating €28,000 produces 6.2% gross. The new build generates more absolute income but the percentage yield is similar. For investors who prioritise yield percentage over absolute income, well-chosen resale stock can be the better pick.

The most practical difference between new build and resale is the timeline. A resale purchase completes in 8–12 weeks from accepted offer. An off-plan new build takes 2–3 years from reservation to key handover, with the risk of delays extending that further. If you need a property to live in or rent out within 6 months, resale is your only option unless you find a completed and unsold new build.

The waiting period for off-plan is not dead time for investors. You have your capital deployed at today’s price with only 30% committed during construction, amplifying your return if the market rises. But it is dead time for personal use. Many buyers we work with compromise: they purchase a resale apartment to use immediately while an off-plan villa is under construction, then sell the apartment when the villa completes. This works particularly well in Puerto Banús where apartment resale liquidity is high.
