In 2026 the Costa del Sol market is dominated by new-build: Marbella, Estepona, Mijas, Benahavís — the bulk of direct sales is projects under construction or pre-construction. But the question still stands: off-plan or move-in-ready?
Straight summary:
Off-plan — when it makes sense
Real advantages:
- Entry price typically 5–15% below equivalent ready inventory, especially at launch.
- Payments staged across the build (typical: 30% during construction, 70% at signing).
- Customisation: finishes, kitchens, bathrooms — before the plans are locked.
- Energy rating A on most current projects (matters for resale and running costs).
- Legal guarantees: the developer is liable for defects between 1 and 10 years depending on the type (under Spain's LOE construction law).
Real risks not to wave away:
- Schedule risk: Costa del Sol deliveries routinely slip 3–12 months. A Q4 2027 delivery date doesn't mean keys in your hand that day.
- Developer risk: only pay deposits to a developer that provides a bank guarantee ringfencing your money in case of default. It's required by Spanish law, but always ask for it in writing.
- Macro changes: a 4% mortgage offer today is not guaranteed when you sign 24 months later.
- You cannot live in or rent the unit during the build.
Move-in-ready (resale)
Real advantages:
- You see exactly what you buy. Real finishes, real views, real neighbours.
- Immediate availability to live in or rent (decisive if you want short-let income from day one).
- On resale you pay ITP 7% instead of VAT 10% — lower closing costs.
- Short timeline: 6–10 weeks from "yes" to signing.
Real drawbacks:
- Higher €/m² in established areas (Nueva Andalucía, Marbella centre, Estepona Playa).
- Energy rating usually worse (C, D, E for properties 15+ years old) — higher running costs and possible renovation work.
- Stock is narrow: the exact property you want in the exact area is not always for sale, and when it surfaces the competition is real.
A practical rule
- Buying to live in or rent immediately with the capital available? — Consider resale as your primary lane.
- Buying as a 3–5 year investment with the patience to wait for delivery? — New-build in a growing area (Mijas Costa, West Estepona, Benahavís) usually offers a better entry price.
- Horizon unclear? — Get terms on both in parallel. We'll give you a real comparison, not the brochure version.
The thing almost nobody mentions
Resale taxation changes if the property has been your main residence. As a non-resident, capital gains are taxed at 19% on the spread. If you buy off-plan and resell before completion (contract assignment), the tax framing differs — speak to a tax lawyer before committing.
