Off-plan vs resale property investment on the Costa del Sol. 5-year NPV comparison, risk assessment, and decision framework for international investors.
problem
Every property investor on the Costa del Sol faces this decision: buy something that exists today, or buy something still being built. Both can deliver strong returns. The right choice depends on your timeline, risk tolerance, and whether you need income immediately.
| Factor | Off-plan | Resale |
|---|---|---|
| Entry price | 10-20% below equivalent completed | Market price |
| Rental income | Delayed until completion (12-36 months) | Immediate |
| Specification | New-build, modern, A-rated energy | Varies; may need renovation |
| Payment structure | Staged over construction period | Full payment at purchase |
| Capital appreciation | Higher potential (buy below market) | Market rate |
| Risk | Construction delay, developer risk | What you see is what you get |
| Tax on purchase | 10% VAT + 1.2% AJD = 11.2% | 7% ITP |
| Warranties | 10-year decenal structural insurance | None (existing condition) |
| Year | Event | Running total invested | Cumulative rental income | Property value (7% annual growth) |
|---|---|---|---|---|

| 1 | Stage payments | €148,000 | - | €316,731 |
| 2 | Completion + balance + taxes | €336,563 | - | €338,902 |

| 4 | Second rental year | €336,563 | €10,124 | €388,009 |
| 5 | Third rental year | €336,563 | €15,186 | €415,170 |
5-year total return: Property value €415,170 + rental income €15,186 - total invested €336,563 = €93,793 (27.9%)
| Year | Event | Running total invested | Cumulative rental income | Property value (7% annual growth) |
|---|---|---|---|---|
| 0 | Purchase + taxes (9.5%) | €350,400 | - | €320,000 |
| 1 | First rental year | €350,400 | €5,062 | €342,400 |
| 2 | Second rental year | €350,400 | €10,124 | €366,368 |
| 3 | Third rental year | €350,400 | €15,186 | €392,014 |
| 4 | Fourth rental year | €350,400 | €20,248 | €419,455 |
| 5 | Fifth rental year | €350,400 | €25,310 | €448,817 |
5-year total return: Property value €448,817 + rental income €25,310 - total invested €350,400 = €123,727 (35.3%)
Note: Resale wins on 5-year total return because of 2 extra years of rental income. Off-plan wins on entry price and specification quality.
We recommend off-plan for investors with a 3 to 5 year horizon who value modern specification and can tolerate the wait for income. We recommend resale for investors who need immediate cash flow or who prefer the certainty of a finished product.
Both strategies work on the western Costa del Sol. The wrong choice isn't choosing at all while prices continue to rise.

Off-plan carries construction and developer risk, mitigated by mandatory bank guarantees. Resale carries condition risk (hidden defects) and no developer warranties.
Delays of 3 to 12 months are common. Your purchase contract should include penalty clauses. Bank guarantees protect your advance payments if the developer fails entirely.
Rarely. Off-plan prices are usually fixed by the developer. Early-phase buyers sometimes get the best unit selection rather than discounts.
Yes. Resale prices are negotiable, typically by 5% to 10% below the asking price depending on the seller's motivation and market conditions.
Off-plan typically shows stronger short-term appreciation because you buy below market. Over 5+ years, both converge towards the general market appreciation rate.
Yes. Independent legal advice is essential for both off-plan (to verify bank guarantees and building licences) and resale (to check for debts, charges, and legal encumbrances on the property).
Off-plan: 10% VAT plus 1.2% stamp duty (11.2% total). Resale: 7% transfer tax (ITP) in Andalucía.

Spanish law provides 1-year finish warranty, 3-year habitability warranty, and 10-year structural (decenal) warranty. Resale properties have no developer warranties.
Resale is simpler: you see what you buy and earn income immediately. Off-plan offers better long-term value but requires patience and confidence in the development. BlancaReal can guide you through either route.
