One of the first and most important decisions any buyer on the Costa del Sol must make is whether to purchase a new build or a resale property. This is not simply an aesthetic preference: the choice has direct implications for taxation, legal guarantees, timescales, total budget and long-term investment strategy.
In 2026, both markets are active and offer real opportunities, but in very different contexts. New build on the Costa del Sol is experiencing a period of strong demand and rising prices, with a supply of high-quality developments that is absorbed rapidly. The resale market, meanwhile, offers greater variety, potential for negotiation and the advantage of knowing exactly what you are buying before you sign.
This article analyses both options in depth so that the international buyer can make an informed decision, with data updated for 2026.
In the Spanish property market, the distinction between new build and resale has very specific legal and tax consequences:
This distinction determines which taxes apply, what guarantees exist and what legal process the purchase follows.
The tax cost of the purchase varies significantly depending on whether it is new build or resale. For buyers in Andalusia, the figures are as follows:
| Item | New build | Resale | Difference |
|---|---|---|---|
| Main tax | VAT 10% | ITP 7% | -3% in favour of resale |
| AJD | 1.2% | 1.2% | Equal |
| Total taxes approx. | ~11.2% | ~8.2% | -3% in favour of resale |
| On a €400,000 purchase | €44,800 | €32,800 | €12,000 less on resale |
| On a €700,000 purchase | €78,400 | €57,400 | €21,000 less on resale |
Resale has a 3 percentage point tax advantage in Andalusia. For a €500,000 property, this represents a saving of €15,000 at the point of purchase — a figure that is far from negligible and must be incorporated into the total budget analysis.

In terms of guarantees, new build significantly outperforms resale. Spanish legislation — in particular the Building Regulation Act (LOE) of 1999 — establishes a mandatory three-tier guarantee system for all new residential construction:
For off-plan purchases — where a property is acquired before it is built or completed — Law 20/2015 requires the developer to guarantee all stage payments made during construction through a bank guarantee or surety insurance. This means that if the developer becomes insolvent or fails to deliver the property within the agreed timeframe, the buyer can claim full repayment of all monies paid, including statutory interest.
This protection, which did not exist before 2015, has represented a radical transformation in the security of the off-plan new build buyer in Spain.
In the resale market, legal guarantees are more limited and the responsibility for verification falls largely on the buyer and their legal team. There is no structural guarantee unless the property is less than 10 years old, in which case the original developer’s insurance may still be in force.
In resale, buyer protection is structured through:
An independent specialist property lawyer is absolutely essential in any resale purchase. Their fees — typically between 1% and 1.5% of the purchase price — are a minor investment compared to the risk of acquiring a property with hidden charges or undetected planning issues.
This is a fundamental difference that many buyers underestimate in their initial analysis:
Practical implications of new build timescales:
New build in 2026 on the Costa del Sol offers construction standards, energy efficiency and design that resale in the same price range cannot match in most cases.

The new build market on the Costa del Sol is experiencing a period of high demand and selective supply in 2026. The main characteristics of the current market are:
This is the most common investor question, and the answer depends on the objective and time horizon:
For immediate rental income: resale wins in most cases. The lower purchase price, lower taxes and immediate availability allow income to be generated from the first month. A well-renovated resale property in Fuengirola, Benalmádena or central Marbella can achieve a gross yield of 5% to 7% with a total investment below that of comparable new build.
For long-term capital appreciation: new build has the advantage in the current market. The off-plan purchase price frequently sits below market value at the time of delivery, generating a latent uplift during the construction period. In high-demand areas such as Estepona or Nueva AndalucĂa, buyers who purchased off-plan in 2022–2023 have recorded appreciations of 20–35% at the time of delivery.
For mixed use (residence + rental): both options are viable, but new build offers advantages in terms of energy efficiency (lower running costs), finish quality (greater appeal to high-purchasing-power tenants) and lower maintenance requirements in the early years.
The choice between new build and resale should be based on a clear analysis of four factors:
New build and resale are both legitimate and attractive options on the Costa del Sol market in 2026, each with real advantages in specific contexts. The key is to align the choice with the buyer’s profile, available budget and short- and long-term objectives.
What is universal in either option: advice from an independent lawyer specialised in Spanish property law is not optional. It is the most cost-effective investment you can make before signing any document.
From a legal guarantees perspective, new build offers more structured protection: 1, 3 and 10-year guarantees by law, and protection of stage payments through mandatory bank guarantee or surety insurance (Law 20/2015). However, “safer” does not mean “risk-free”: the greatest risk in new build is delayed delivery or, in extreme cases, developer insolvency. In resale, the main risk is acquiring a property with hidden charges, planning issues or a worse-than-expected condition. In both cases, advice from a specialist lawyer and, in resale, a professional technical inspection eliminate the vast majority of risks before signing.
Negotiation works very differently in both markets. In resale, negotiation is habitual and expected: offers 5–10% below the asking price are common and often accepted, especially if the property has been on the market for some time. In new build, the developer rarely accepts discounts from the list price, as they work with margins calculated on construction costs and commitments to the financing bank. However, in new build it is possible to negotiate other aspects: included garage space or storage unit, choice of premium finishes at no extra cost, upgrades to kitchen or bathrooms, or in some cases more flexible payment terms. In a high-demand market such as the Costa del Sol in 2026, negotiation on new build is limited, especially in high-absorption developments.
Law 20/2015 protects the buyer very effectively in this situation. If the developer fails to deliver the property within the agreed timeframe — plus the agreed extension margin — the buyer has two options: rescind the contract and recover all monies paid in full plus statutory interest, by executing the bank guarantee or surety insurance that the developer is required to hold; or maintain the contract and claim compensation for the losses caused by the delay. In practice, the bank guarantee is the most solid protection: it allows the buyer to recover their money without depending on the developer’s solvency or a court process. Verifying that the guarantee is correctly constituted — before making any stage payment — is one of the most important functions of the buyer’s lawyer.
In many cases, yes, and it can be one of the most profitable investment strategies in the market. The price difference between an unrenovated resale property and a fully updated one in the same location and development can exceed 30–40% in areas such as Nueva AndalucĂa, Fuengirola or Benalmádena. If the renovation cost — which for a mid-quality property typically ranges between €800 and €1,500/m² — is less than that value difference, the transaction generates positive returns both on sale and on rental. The keys to making renovation profitable are: choosing the right location (established development with real demand), working with an architect or building surveyor who manages the renovation with guarantees on timescales and price, and updating the elements that most impact perceived value: kitchen, bathrooms, flooring, windows and climate control.
Yes, although in general terms financing is accessible for both options. For new build, banks typically finance up to 70% of the purchase price (or the appraisal value, whichever is lower), with conditions that may vary depending on the developer: some have preferential agreements with banks that offer improved terms to buyers of their developments. For resale, financing is similar — up to 70% of the appraisal value for non-residents — but the process is more standard and without the developer-bank agreements. Non-residents in Spain have access to mortgages from Spanish institutions, although with a somewhat more conservative financing percentage than for residents. In any case, obtaining mortgage pre-approval before beginning the search is a highly recommended practice that strengthens the buyer’s negotiating position.
