Both are legitimate ways to buy on the Costa del Sol. The right one depends on your timeline, your appetite for construction risk, and what you actually want the property to do for you.
Neither is inherently the better investment -- they suit different buyers, timelines and risk tolerances. Compare them below on the points that actually affect your decision.
Usually priced below a comparable finished home, since you are committing years ahead of delivery and taking on construction timeline risk. That gap narrows, or closes, as a project moves toward its final released units.
Staged: a reservation, a larger payment on signing the private purchase contract, further payments at construction milestones, and the balance on completion.
Construction and delivery risk: the project could be delayed or, worst case, not completed. Payments made before completion are required by law to be bank-guaranteed.
Buying early sometimes means a genuine say in finishes -- flooring, kitchen options, occasionally layout -- depending how far along construction is. That window closes near completion.
Waiting, sometimes years, for delivery. The developer's track record for hitting its delivery date deserves real scrutiny.
The case is buying below completed-market price and the value closing that gap by delivery. This depends on the specific project and area performing as expected -- it is not a guarantee.
A formal snagging inspection happens before or at handover, with defects listed for the developer to fix under the build warranty. You are working from the developer's finish standard, not judging an existing property.
Completion depends on the developer obtaining the first occupation license and certificate of completion before the deed can be signed at the notary. Your lawyer confirms these are in place before you complete.
Happens once the building is finished and licensed, on a date the developer estimates rather than guarantees. Delays of a few months against the original estimate are not unusual.
Costs more upfront, but you are paying for a known quantity: the actual finish, the actual view, the actual noise level, none of which you can fully judge from a floorplan and a render.
Simpler: reserve, sign, pay the balance, usually within 30 to 60 days. No construction-linked schedule, and no way to spread the cost over time.
Removed entirely. What you see is what you get, and you can inspect the actual property before committing to anything.
Fixed. A limitation if you wanted something different, an advantage if you would rather judge real materials and workmanship than a specification sheet.
Can generate rental income or be lived in immediately after completion, with no construction timeline in the way.
Easier to benchmark against genuinely comparable recent sales in the same building or area -- real, current data rather than a projection.
Not applicable in the same way. Any defects are whatever the current owner has or has not addressed, so a professional survey before you commit matters more here than a developer warranty.
Already issued and checkable: your lawyer verifies the existing title, license history and any charges on the property at the Land Registry before you sign.
Set by you and the seller, typically 30 to 60 days after signing, with no construction or licensing timeline to depend on.
It covers payments made ahead of completion specifically. The exact scope and validity of the guarantee for a given project is something to confirm in writing before signing, not something to assume.
Off-plan tends to suit buyers who do not need the property immediately, want to spread payments over time, and are comfortable with construction-stage risk in exchange for a lower entry price and, in some cases, a say in the finish.
A completed home tends to suit buyers who want to move in, rent out, or simply see exactly what they are buying without waiting or without taking on delivery risk -- often at a higher upfront cost for that certainty.
Most buyers are not purely one or the other. The honest way to decide is to compare specific projects against your own budget, timeline and risk tolerance, rather than deciding on off-plan versus resale as an abstract category first. For the full step-by-step process once you have decided, see how buying works.
Most comparisons stop at the asking price. In Andalucía the two purchases are taxed differently, and the difference is large enough to change which one is actually cheaper.
IVA at 10% plus AJD at 1.2%, so 11.2% of the price in tax. Both are set by law and neither is negotiable.
ITP at 7% and no AJD. Four points lower, on the same price.
A resale at the same headline price costs roughly €18,000 less in tax on a €450,000 purchase. An off-plan unit has to be priced meaningfully below the finished comparable before it is the cheaper transaction, not merely the cheaper number.
That does not settle the question. It does mean the comparison is not the one the asking prices suggest, and it belongs in the arithmetic before anything else.
Off-plan risk is easy to name: the building might be late. Resale risk is quieter, because it arrives attached to the property rather than to the timeline.
Unpaid community charges attach to the property itself for the current year and the three preceding ones, and unpaid IBI attaches to it without a time limit of that kind. Your lawyer asks for a certificate of no debt from the community and checks the IBI receipts before you sign.
Where the seller is not resident in Spain, the buyer withholds 3% of the price and pays it to the tax office on the seller's account. It is the buyer's obligation, not the seller's courtesy, and it does not arise at all buying from a developer.
Extensions, glazed terraces and pool houses added without permission are common and do not always appear in the deed. What is registered, what is built and what was licensed have to agree, and only a search establishes that.
A new-build carries statutory cover against defects. A resale carries whatever remains of the original periods, which on an older home is usually nothing, so a survey does the work a warranty would.
None of this makes resale the worse choice. It makes the diligence different: on off-plan you are checking a developer and a licence, and on a resale you are checking a building and its history.
At the same headline price, no, because the tax is four points higher. Off-plan is cheaper where the price genuinely sits below the finished comparable by more than that, which is a project-by-project question rather than a rule.
Yes, but the loan is normally drawn at completion rather than during construction, so the stage payments come out of your own funds. That changes the cash profile more than the total, and it is worth modelling before you reserve.
Delays of a few months against the original estimate are common. Your contract sets the delivery date and what happens if it is missed, including whether you may terminate or grant an extension, and that clause is worth reading before you sign rather than after.
Sometimes. Whether the contract can be assigned to another buyer, and on what terms and fee, is set by the developer and varies widely. If that is part of your plan, establish it in writing before reserving, not later.
A completed home can be let immediately, which is a real advantage where income matters from day one. Beyond that, letting depends on the specific development's rules and the local licensing regime rather than on whether the home was bought off-plan.
Contrato de compraventa -- the binding agreement setting out price, payment schedule, specification and delivery terms, signed after reservation.
Legally required protection for off-plan payments made before completion, covering you if the development is not delivered.
A formal inspection before or at handover to list defects for the developer to fix under the build warranty.
Licencia de primera ocupacion -- the official confirmation a newly built home is fit to be lived in, required before completion.
The community of owners that manages and charges for shared areas and services in a development, whether off-plan or resale.
The deed of sale signed at the notary and registered in your name at completion.
The two routes are also taxed differently: new-build carries IVA and AJD, resale carries ITP. See what a new-build actually costs in Andalucia for the figures.
