The Fundamental Choice
One of the first decisions UK buyers face is whether to buy a resale property (segunda mano) or a new build (obra nueva). Both have distinct advantages and disadvantages, and the right choice depends on your budget, timeline, risk tolerance, and priorities. This guide breaks down every factor you need to consider.
In Spain, the distinction between resale and new build goes beyond just the age of the property — it affects the taxes you pay, the legal protections you receive, the financing options available, and even the buying process itself.
Tax Differences: ITP vs IVA + AJD
The tax treatment is fundamentally different, and this is often the first thing UK buyers notice:
Resale Properties: ITP
When you buy a resale property, you pay Impuesto de Transmisiones Patrimoniales (ITP) — the transfer tax. Rates vary by region:
- Andalusia: 7%
- Valencia/Catalonia: 10%
- Madrid: 6%
- Balearics: 8-13% (graduated)
- Canaries: 6.5%
New Builds: IVA + AJD
When you buy a new-build property (first sale from the developer), you pay:
- IVA (VAT): 10% on mainland Spain (7% IGIC in the Canary Islands)
- AJD (Stamp Duty): 1.2% in Andalusia (varies by region: 0.75% in Madrid, 1.5% in Valencia and Catalonia)
- Total: 11.2% in Andalusia (varies: 10.75% in Madrid, 11.5% in Valencia/Catalonia)
Tax comparison on a €300,000 property:
- Resale in Andalusia: €21,000 (7% ITP)
- Resale in Valencia: €30,000 (10% ITP)
- New build (mainland): €33,600 (10% IVA + 1.2% AJD)
In most regions, new builds are slightly more expensive on tax. The exception is low-ITP regions like Madrid (6%) where the difference is more pronounced, and high-ITP regions like Valencia (10%) where the costs are closer.
Quality and Guarantees
New Build Guarantees
New-build properties in Spain come with mandatory insurance guarantees under the Ley de Ordenación de la Edificación (LOE):
- 1-year guarantee: Covering finishing defects (paint, tiles, door handles, etc.). The developer must fix any cosmetic issues reported within the first year
- 3-year guarantee: Covering habitability defects — issues that affect the property's use, such as leaking pipes, defective waterproofing, or faulty electrics
- 10-year guarantee (seguro decenal): Covering structural defects — problems with the foundations, load-bearing walls, or structural frame. This is backed by a mandatory insurance policy (seguro decenal) taken out by the developer
These guarantees are legally enforceable and represent genuine protection. If a structural problem appears in year 8, the insurance policy covers the repair. This is significantly more protection than you get with a resale property, where you buy "as seen" with no warranties.
Resale: No Guarantees
When you buy resale, the property is sold in its current condition. Any defects — structural, cosmetic, or hidden — are your problem from completion day. This is why we strongly recommend a professional survey before buying a resale property. The few hundred euros it costs is insignificant compared to discovering a €20,000 structural problem after you've completed.
Negotiation Room
Resale: More Room to Negotiate
Resale properties typically offer more negotiating room. Sellers are individuals with personal circumstances — they may be motivated by divorce, inheritance, financial pressure, or simply wanting to sell quickly. Depending on market conditions and the seller's motivation, discounts of 5-15% from the asking price are common on resale properties in many parts of Spain.
Factors that increase negotiating power:
- Property has been on the market for over 6 months
- Seller has already bought another property
- Property needs modernisation
- You're a cash buyer (no mortgage delays)
- Off-season timing (winter months)
New Build: Less Flexibility
Developers set prices based on their costs and target margins, and there's typically less room for negotiation on price. However, developers may offer:

- Furniture packages included

- Payment of stamp duty (AJD)
- Deferred payment plans
- Garage or storage room included at no extra cost
These concessions may be worth €5,000-€15,000 but won't show up as a lower headline price. The best negotiating position is buying end-of-phase or when the developer needs to sell remaining stock.
Location
Resale: Established, Central Locations
The biggest advantage of resale is location. Older properties are in established areas with proven infrastructure: shops, restaurants, schools, transport links, and established communities. You can walk around the neighbourhood, visit at different times of day, check noise levels, and see exactly what you're getting.
In popular coastal towns like Javea, Moraira, Altea, or Marbella, the best locations were built on decades ago. If you want a beachfront apartment, a village-centre townhouse, or a villa in a mature, established urbanisation with full-grown gardens, you're looking at resale.
New Build: Often Further Out
New developments tend to be located on the edges of towns or in newer urbanisations, where land is available for development. This can mean:
- Further from the beach or town centre
- Less established infrastructure (shops, restaurants may be limited nearby)
- Less mature landscaping (new gardens need 3-5 years to establish)
- Construction noise from neighbouring phases still being built
However, some new developments are on exceptional sites — former industrial land being regenerated, or infill plots in desirable areas. Always visit the location and surrounding area before committing to an off-plan purchase.
Bank Guarantee on Off-Plan Deposits
If you're buying off-plan (signing a contract and paying stage payments while the property is being built), Spanish law provides crucial protection: the developer must provide a bank guarantee (aval bancario) or insurance policy covering all payments you make during construction. This is required by Ley 38/1999 and ensures that if the developer goes bust before completing the project, you get all your money back.
After the 2008 financial crisis, when dozens of Spanish developers went bankrupt leaving UK buyers with nothing, this protection was strengthened. Courts consistently ruled in favour of buyers, and Spanish Supreme Court decisions in 2015-2018 made banks jointly liable for returning deposits even when the developer had failed to arrange the bank guarantee.
Essential checks for off-plan purchases:
- Ensure you receive an individual bank guarantee certificate for every payment you make
- Verify the guarantee is from a reputable Spanish bank
- Never pay directly to the developer's general account — payments should go to a special account (cuenta especial) linked to the bank guarantee
- Keep all payment receipts and guarantee certificates in a safe place
Snagging and Defects
New Builds: Expect Snagging
Even high-quality new builds have defects when they're first delivered. Spanish construction quality has improved significantly since the pre-crisis boom years, but snagging issues are still common:
- Paint imperfections and touch-ups needed
- Tiles not perfectly aligned
- Door frames slightly off-square
- Minor plumbing drips
- Electrical socket placement errors
- Scratched windows or damaged hardware
When you take delivery of a new-build property, arrange a snagging inspection before signing the delivery document (acta de entrega). You or your appointed surveyor should walk through every room with a checklist. All defects should be recorded in writing and the developer given a deadline (typically 30-60 days) to fix them.
Resale: What You See Is What You Get
With a resale property, there's no snagging list — the property is sold in its current state. Any issues you discover after completion are your responsibility. This makes a pre-purchase survey even more critical for resale properties.
Renovation Costs on Resale
Many UK buyers are attracted to resale properties precisely because they want to renovate — installing their own kitchen, updating bathrooms, and putting their personal stamp on the property. But renovation costs in Spain should be carefully budgeted:
- Full kitchen renovation: €8,000-€25,000 depending on size and specification
- Full bathroom renovation: €4,000-€12,000 per bathroom
- Complete rewire: €3,000-€8,000 for a 3-bedroom property
- New windows (double glazing): €3,000-€10,000 for a typical property
- Pool installation: €15,000-€35,000 depending on size and finish
- Air conditioning (whole house): €3,000-€8,000
- Full renovation (turnkey): €500-€1,200 per square metre
A resale property that's €50,000 cheaper than a new build but needs €40,000 of renovation isn't necessarily a bargain, especially when you factor in the stress, time, and uncertainty of managing renovation works in a foreign country. That said, a well-renovated resale property in a prime location can offer better value than a new build in a peripheral location.
Making Your Decision
Choose resale if:
- Location is your top priority — you want a specific street, village, or beachfront
- You want a property with character (traditional finca, village house, established garden)
- You're a confident negotiator willing to push for a good deal
- You're handy or have reliable contacts for renovation work
- You want to move in quickly (no construction delays)
Choose new build if:
- Modern design, energy efficiency, and low maintenance are priorities
- You want legal guarantees (1/3/10-year warranty)
- You're buying remotely and want the protection of bank-guaranteed stage payments
- You prefer a move-in-ready property with no renovation needed
- You're buying for investment and want a modern property with broad rental appeal
There's no universally "better" option — it depends entirely on what you value most. Many UK buyers look at both resale and new build properties before deciding, and we'd recommend keeping your options open until you've seen what's available in your chosen area and budget.

Financing Differences: Mortgage Considerations
Spanish banks treat resale and new-build purchases differently when it comes to mortgages. For resale properties, the bank values the property based on comparable recent sales in the area. For new builds, especially off-plan, the bank may be willing to lend based on the projected completion value, but the mortgage won't be finalised until the property is built and valued.
If you're buying off-plan, you'll need to fund the stage payments (typically 20-30% of the purchase price during construction) from your own resources — the mortgage only kicks in at completion. This means you need more upfront cash for an off-plan purchase compared to a resale where the mortgage covers everything from day one.
Some developers have arrangements with specific banks offering pre-approved mortgages to buyers in their developments. These can be convenient but may not offer the best rates. Always compare the developer's preferred bank with independent mortgage offers. Your mortgage broker or lawyer can help you assess the best financing structure for your specific situation, whether you're buying a character resale property or a modern new build.
