Off-Plan vs Resale in Marbella: Decision Framework with a €3M Worked Example
The choice is rarely about price. The choice is about time, customisation, risk allocation, and tax structure — and on a €3M Marbella deal the structural delta between off-plan and resale is roughly €230,000 in transaction costs, 24 months of opportunity cost, and a fundamentally different risk profile that most buyers do not price correctly. The right answer depends on your timeline and your liquidity, not on which one looks cheaper per square metre.
Direct answer
Off-plan in Marbella means buying a property under construction or pre-construction from the developer (promotor), typically with a 30-40% deposit schedule spread across the build period (12-30 months from signing to keys), 10% IVA + 1.2% AJD on the price, and exposure to builder risk (delivery delay, specification changes, developer insolvency). Resale means buying a finished, previously-occupied property from a private seller, with a single 10% arras + 90% balance at notary 30-60 days later, 7% ITP transfer tax (Andalucía), immediate occupancy, no customisation, and exposure to hidden defect risk that a building survey can mostly mitigate. On a €3M deal the transaction cost delta is €126,000 in seller-tax stack (10% IVA + 1.2% AJD = 11.2% vs 7% ITP = 4.2% difference) plus 24 months of capital tied up vs immediate use. Off-plan wins for buyers with 18-30 month horizons, customisation appetite, and faith in the specific developer; resale wins for buyers wanting immediate occupancy, lower transaction tax, and the safety of seeing what they buy.
The two routes side-by-side
| Dimension | Off-plan (new-build) | Resale (existing) |
|---|---|---|
| Time to keys | 12-30 months from signing | 30-60 days from arras |
| Transaction tax | 10% IVA + 1.2% AJD = 11.2% | 7% ITP (Andalucía) |
| Total tax + fees | 12-14% above price | 9-11% above price |
| Deposit schedule | Staged: 10% reservation, 20-30% during build, balance at completion | 10% arras, 90% at notary |
| Customisation | High — finishes, layout (within builder's variation menu) | Zero — what you see |
| Builder risk | High — Ley 57/1968 protects deposits, but delivery delay still bites | None — risk shifts to hidden defects |
| Hidden defect risk | Low (10-yr triennial liability under LOE Art 17) | Medium-High (structural defects can surface years later) |
| Capital efficiency | Low — capital tied 12-30 months for no occupancy | High — immediate use or rental |
| Mortgage availability | Limited — bank values at completion, refinance often required | Standard — 60-70% LTV for non-resident |
| Furnishing | Often included or "turnkey" upgrade option | Rare — typically unfurnished |
| Negotiation room | Low — developer prices fixed; possibly extras included | Medium — 5-15% off asking common in 2026 market |
The headline tax delta — 11.2% vs 7% in Andalucía — is the most quoted difference and the most misleading. The full transaction-cost stack including notary, registry, legal, gestoría, and bank/FX adds 1-3% on each side, narrowing the gap to roughly 3-4 percentage points net. On €3M that is €90,000-€120,000 in real cash difference, before any consideration of opportunity cost.
Worked example: €3M off-plan vs resale
Same Sierra Blanca-tier villa, two routes. Buyer is a non-resident UK pensioner with €3.5M of liquid capital, 60% LTV mortgage approved.
Route A — €3M off-plan from developer
- Reservation deposit: €30,000 paid at signing of compromiso (June 2026)
- Stage payment 1 (after building licence + foundations): €270,000 (October 2026)
- Stage payment 2 (after structure complete): €300,000 (April 2027)
- Stage payment 3 (after finishing trades): €300,000 (October 2027)
- Final balance + 11.2% IVA/AJD at completion (December 2027): €1,800,000 + €336,000 = €2,136,000
- Notary, registry, legal, gestoría, bank/FX: ~€60,000
Total cash out by December 2027: €3,096,000. Capital tied 18 months without occupancy. No rental income during build.
Risks: developer delivery delay (typical Marbella off-plan: 2-6 months over deadline), specification disputes (the show-villa marble is not the delivered marble), developer insolvency (Ley 57/1968 / Ley 38/1999 mandates bank guarantee — verify it exists, in writing, before signing).
Route B — €3M resale, same Sierra Blanca tier
- Reserva: €15,000 paid at offer acceptance (June 2026)
- Arras: €285,000 paid 14 days later (June 2026), under penitenciales per Civil Code Art 1454
- Balance at notary 45 days later (August 2026): €2,700,000
- ITP 7% Andalucía: €210,000 paid within 30 days
- Notary, registry, legal, gestoría, bank/FX: ~€60,000
Total cash out by September 2026: €2,970,000. Immediate occupancy; potential rental yield from October 2026 if holiday-let licensed.
Risks: hidden structural defects (mitigated by pre-purchase architect technical survey, €600-€2,000), embargos and debts attached to property (mitigated by 14-point due diligence checklist), Catastro / urbanismo discrepancies (the largest hidden-risk category in Marbella resale).
Side-by-side outcome
| Metric | Off-plan | Resale |
|---|---|---|
| Cash out total | €3,096,000 | €2,970,000 |
| Tax cost | €336,000 | €210,000 |
| Months to occupancy | 18 | 1 |
| Lost rental opportunity (€8K/month at 60% occupancy) | ~€86,400 | €0 |
| Effective net cost difference | — | ~€212,000 cheaper |
Resale is structurally cheaper by roughly €212,000 on this fact pattern. Off-plan wins back ground only if (a) the off-plan unit appreciates 8-12% during build (possible in tight micromarkets), (b) the buyer values the 5-7 year warranty stack (Spanish LOE Art 17: 1 year cosmetic, 3 years habitability, 10 years structural), or (c) customisation is itself worth €100,000+ (luxury kitchen, smart-home wiring, layout changes only available pre-construction).
Where buyers commonly trip up
Underestimating builder risk. Marbella has roughly 60 active developers in the €3M-€15M tier; perhaps 15-20 are institutional grade with deep balance sheets. The remaining 40-45 are SPV (single-purpose vehicle) developers — one project, one bank loan, finite resilience to delay or cost overrun. Always verify the developer's prior project track record and the bank guarantee (aval bancario) under Ley 38/1999 that secures your stage payments against developer insolvency.
Misreading the IVA recovery story. Buyers are sometimes told "you can recover IVA if you set up an SL". This is partly true — IVA is recoverable on commercial-use properties via SL ownership, but the property must be genuinely commercial-use (rental-only with declared rental activity), and Spanish corporate tax of 25% on rental income typically eats the IVA saving over a 5-7 year horizon. See our buying fees breakdown for the full corporate-vs-personal cost map.
Skipping the 10-year liability check on resale. Spanish Construction Law (LOE) Art 17 imposes 10-year structural liability on the original builder. If you buy a 7-year-old resale and the structure fails in year 9, you have 12 months from defect discovery to sue the original builder — but only if the defect is documented immediately. Skip the architect technical survey at purchase and the warranty becomes effectively unenforceable. See our pre-purchase building survey guide.
Overpaying for "turnkey" off-plan furnishing packages. Developer turnkey packages are typically priced at 1.3-1.6x what the same furnishings would cost a private buyer commissioning an interior designer. The convenience is real; the markup is also real. Negotiate hard or buy direct.
Ignoring the off-plan completion-month tax mismatch. A unit signed in 2026 and completed in 2028 may be subject to 2028 IVA rate, 2028 AJD rate, 2028 valor de referencia. Tax rules can shift over the 18-30 month build window. Build a 5-10% tax-cost contingency into your model.
Buying off-plan as "tax efficient" without modelling cash drag. The 18-30 months of capital tied without occupancy or rental income is a hidden cost that off-plan brochures never mention. At 4-5% opportunity cost on €1M staged across 24 months, the silent loss is €40,000-€60,000.
When to call Muse
Before you sign a developer reservation OR a private-seller arras. The decision framework above assumes a clean developer and a clean resale; in practice both options carry meaningful diligence work that should be completed BEFORE the reservation deposit, not after.
FAQ
Are the deposit stage payments on off-plan protected against developer failure? Yes — Ley 38/1999 (LOE) and Ley 57/1968 (the residential-construction deposit law) require the developer to secure all stage payments via a bank guarantee (aval bancario) or insurance policy (seguro de caución). This protects the deposits if the developer goes insolvent or fails to deliver. CRITICAL: verify in writing that the aval is in place AND covers your specific stage payment, before sending each tranche. Browse off-plan options in our property database to start the file.
Can I sell an off-plan unit before completion? Yes — typically via "subrogación" of the purchase contract to a new buyer, with developer consent. Marbella off-plan flipping was lucrative in 2003-2007 and again in 2021-2024; in cooler markets the resale liquidity for off-plan contracts dries up rapidly. Build a 12-18 month hold expectation minimum.
What is the developer's warranty on off-plan? Spanish Construction Law (LOE) Art 17 imposes three warranty periods on the original builder: 1 year on cosmetic defects (terminación o acabado), 3 years on habitability defects (elementos constructivos), 10 years on structural defects (vicios estructurales). The 10-year structural warranty is backed by mandatory insurance (seguro decenal). Always retain the seguro decenal certificate at completion.
Is off-plan more or less risky than resale in 2026? Different risks, not more or less. Off-plan: developer execution and market timing. Resale: hidden defects, urbanismo issues, embargos. Both manageable with the right professional team. See the comparative quality framework in our new-build vs old construction guide.
What about the Marbella PGOU and licensing risk on off-plan? A real concern. Marbella's urban planning regulations (Plan General de Ordenación Urbana) have shifted multiple times in the last decade, and several developments started under one PGOU were challenged or modified mid-build. Verify (a) the developer has full final building licence (licencia de obra), not provisional, AND (b) the licencia de primera ocupación pathway is clear. The full transaction-stack discipline lives in our Marbella property buying complete guide.
