If you’re comparing options on the Costa Blanca, one of the first decisions is whether to buy new build or resale. Both are common in this part of Spain, and neither is automatically the right answer — the decision usually comes down to what you value most: guarantees and running costs, or an established location you can walk through today. This guide covers the real differences.
The legal guarantees are genuinely different
This is the single biggest practical difference, and it’s worth understanding properly rather than taking on trust. Every new build home sold by a developer in Spain is legally required to carry a tiered structural warranty, backed by insurance from a company independent of the developer — not just a promise from the builder:
- 10 years for defects affecting the structure itself — foundations, load-bearing walls, and similar fundamental elements.
- 3 years for defects affecting habitability — issues like water ingress, insulation failures, or waterproofing problems.
- 1 year for cosmetic and finishing defects.
Resale property carries no equivalent guarantee. Spanish law does give resale buyers some protection against hidden defects, but it’s considerably narrower in practice: the defect has to be serious enough to threaten the property’s stability, it can’t have been visible at the time of purchase, and you typically have five years to bring a claim — and you’ll need to prove the defect already existed when you bought. It’s a real protection, but a much higher bar than an insurance-backed 10-year structural warranty.
Buyers of a new build home under construction also benefit from a separate protection during the build itself: any payments made on account before completion must be covered by a bank guarantee (aval) or insurance policy under Ley 38/1999, so your deposit is protected even if the developer were to run into difficulty before finishing the build.
Running costs and building standards
New build homes in Spain are built to current regulations on thermal insulation, ventilation, and energy efficiency — rules that didn’t exist, or were far less strict, when many resale properties were built. In practice, this generally means lower heating and cooling bills, and fewer of the small ongoing repairs that come with ageing plumbing, wiring, or roofing. A resale property, particularly an older one, may need updating to modern insulation or systems standards to match — a cost worth budgeting for if you’re comparing purchase prices directly.
Location trade-offs
Resale property has a genuine advantage here: it tends to sit in established, already-built-out neighbourhoods, close to amenities that have had years to mature — shops, restaurants, transport links, and a settled community. New developments are sometimes built on land at the edge of an existing town as it expands, which can mean a newer, quieter setting, but occasionally a slightly longer walk to established amenities, depending on exactly where the development sits.
This varies a lot by specific location, though — a development within an already well-established urbanisation, like Ciudad Quesada, doesn’t carry the same “edge of town, wait for it to develop” trade-off as a new build in a genuinely emerging area. It’s worth judging each specific location on its own terms rather than assuming new build always means further out.
Price
New build homes are often priced at a premium over comparable resale property, reflecting current building costs, modern specification, and the guarantees described above. Whether that premium is worth it depends on how much you value those guarantees and lower running costs versus paying less for something already complete.
Timing and delays
Buying off-plan or during construction means accepting a completion date that’s an estimate rather than a certainty — construction can run behind schedule for reasons outside anyone’s control, from weather to supply delays. A resale property, by contrast, is what it is: you can view it, inspect it, and move in on a timeline you control far more precisely, without waiting on a build.
Which is right for you?
As a rough guide:
- New build tends to suit buyers who want the legal guarantees, prefer lower running costs, want some say in the finish, and can be flexible on the exact completion date.
- Resale tends to suit buyers who want to move in immediately, want an established location above all else, and are comfortable inspecting a property as-is with a narrower legal safety net.
Residencial Montesol: new build, with the guarantees explained upfront
Residencial Montesol is a small new build development of two townhouses in Ciudad Quesada — an already well-established urbanisation, not an emerging area on the edge of town, so the usual “new build means further out” trade-off doesn’t really apply here. We set out the specific guarantees that apply to this development, in plain terms, on our Guarantees section and our About Us page, alongside dated construction progress updates so you can follow the build rather than just take our word for it.
See our The Homes page for the full specification, or get in touch via our Contact page with any questions.

Frequently asked questions
Is new build always more expensive than resale?
Generally yes, per square metre, reflecting current building costs, modern specification and legal guarantees — though the gap varies by area and specific property, and running costs can partly offset the higher purchase price over time.
Can I negotiate the price on a new build home?
Less room for negotiation typically exists on new build pricing compared with resale, particularly on a small development, though this varies by developer and how far along the build is.
Does new build mean I can’t move in for years?
Not necessarily — it depends entirely on the specific development’s stage of construction. Some new build purchases complete within months, others are sold well before groundbreaking; always confirm the realistic timeline for a specific property rather than assuming either extreme.
What happens if a new build developer has problems during construction?
Any amount you’ve paid on account before completion must be protected by a bank guarantee or insurance policy under Spanish law (Ley 38/1999), specifically to protect buyers in this situation.
Is the 10-year warranty transferable if I sell the property?
Generally yes, for the remainder of its term — the seguro decenal attaches to the property rather than the original buyer, though this is worth confirming with your lawyer for the specific policy in question.
