Off-plan vs key-ready property in Spain — which is better?

Off-plan (sobre plano) means buying before or during construction; key-ready (llave en mano) means the home is finished and you complete immediately. Both are common in Spain's new-build market — the right choice depends on your appetite for completion risk versus your need for certainty. Off-plan — pros: lower entry price, staged payments during the build, first pick of units, and potential price appreciation between reservation and completion. Cons: completion risk (delay or, rarely, developer failure), capital tied up before you can let or live, and you buy from plans, not a finished home. In Spain, off-plan deposits must be bank-guaranteed by law (Ley 38/1999) — never pay a stage payment without the guarantee. Key-ready — pros: what you see is what you get, immediate rental income or occupancy, no completion risk, easier to mortgage. Cons: higher price, less choice of unit, no appreciation runway before completion. How Avena frames it: completion risk is an explicit factor in the Avena Investment Score (5% weight) and every developer carries a quality grade (AAV to DV). A keenly-priced off-plan from a top-graded developer can outscore a key-ready unit; a thin-track-record developer rarely does. The score lets you compare the two on equal terms.
