Alianz Group Review 2026: Costa del Sol Agency Verdict
Is Alianz Group worth using? 15+ years on Costa del Sol, inventory hubs in Marbella, Mijas, Estepona and Fuengirola, fees to check, and our 2026 verdict.
By Invest Spain Property Editorial · Updated June 17, 2026 · 8 min read
Quick Answer: Alianz Estates (Alianz Group) is a Costa del Sol estate agency with 15+ years of market presence per corporate materials, curating luxury resale and new-build stock across Marbella, Mijas, Estepona, Fuengirola, and wider Málaga province. June 2026 inventory lists 37 active properties from approximately €360,000 to €10.5M. Invest Spain Property publishes five bilingual hubs; confirm live availability on alianzgroup.es before any offer.
International buyers on Costa del Sol often choose between buying directly from a stock-listed developer or working through a local agency that filters resale, renovated, and obra nueva stock across municipalities. Alianz Group sits in the second camp: a bilingual desk with photography-rich listings, area landing pages, and a promotions channel for new developments. This review explains how Alianz differs from developer reviews elsewhere on Invest Spain Property, where its inventory clusters geographically, and the due diligence steps every non-resident purchaser should complete.

Who is Alianz Group and how do they operate?
Alianz Estates is a Costa del Sol real-estate agency trading as Alianz Group, combining consulting, development partnerships, and residential sales under a bilingual English–Spanish website. Corporate schema on alianzgroup.es describes a RealEstateAgent entity covering Marbella, Estepona, Fuengirola, Mijas, and Málaga. Unlike Madrid-listed developers, Alianz does not publish a single consolidated balance sheet for every listing; legal counterparty varies per property.
The agency’s June 2026 Supabase backend exposes 37 residential listings with granular photography, indicative pricing, and address-level metadata. Legacy marketing URLs such as /en/obra-nueva-marbella currently resolve to the SPA homepage shell, while live filters sit at /propiedades/marbella, /propiedades/mijas, /propiedades/estepona, /propiedades/fuengirola, and /promociones for new developments.
| Operating signal | June 2026 context | Buyer relevance |
|---|---|---|
| Active listings | 37 properties in Supabase | Broad but fast-moving inventory |
| Price span | €360,000 to €10.5M | Covers mid-market to ultra-prime |
| Photography | Dedicated Supabase image table | High marketing quality per unit |
| Geography | Costa del Sol focus | Municipality-specific rental rules |
| Site stack | Lovable SPA + Supabase | Confirm live URLs before travel |
Published Invest Spain Property hubs (5/5 curated layer)
Invest Spain Property maps the Alianz curated portfolio into five English investor hubs aligned with municipality demand.
| Hub slug | Municipality focus | June 2026 listings | Entry band |
|---|---|---|---|
| Obra Nueva Marbella | Marbella and Benahavís | 5 | €795,000 |
| Obra Nueva Mijas | Mijas and La Cala | 3 | €589,000 |
| Obra Nueva Estepona | Estepona and Selwo | 5 | €450,000 |
| Obra Nueva Fuengirola | Fuengirola and Higuerón | 3 | €380,000 |
| New Developments | Costa del Sol-wide | 36 | €360,000 |
Each hub translates agency inventory into tables, rental notes, and risk checklists. Treat them as screening tools, not replacements for lawyer-led due diligence on individual escrituras.
Agency workflow versus developer off-plan purchases
When Alianz markets obra nueva inside a wider resale portfolio, buyers must still separate agency marketing from promoter obligations. Resale purchases use ITP transfer tax in Andalucía; primary sales from developers use IVA and AJD with milestone payments protected under Ley 38/1999 when correctly documented.
- Identify the legal seller on the reservation contract: agency versus promoter.
- Request community statutes before paying arras on apartments and townhouses.
- Verify bank guarantees on any staged payment marketed as off-plan.
- Model net yield with IBI, community fees, management, and non-resident tax.
- Commission snagging on delivered stock prior to notary.
Risks international buyers should plan for
Agency breadth is an advantage for comparison shopping but introduces heterogeneity risk: each listing carries its own debts, licences, and community rules.
- Inventory churn: High-turnover desks can show sold units online briefly.
- URL drift: Old English hub paths may not deep-link to filters, bookmark live
/propiedades/*URLs. - Yield claims: Turnkey rental language needs independent net modelling.
- Ultra-prime concentration: Marbella penthouses above €2M require liquidity planning on exit.
Municipality breakdown and demand drivers
Alianz inventory clusters along the western Costa del Sol corridor where British, Nordic, and domestic Madrid buyers still absorb both lifestyle and rental product. June 2026 Supabase addresses show five Marbella listings (including Benahavís micro-markets), five Estepona listings, three Mijas listings, three Fuengirola listings, plus Benalmádena, Vélez-Málaga, and Málaga city stock inside the wider portfolio.
| Municipality | Listings (subset) | Buyer profile | Rental angle |
|---|---|---|---|
| Marbella | 5 | Ultra-prime lifestyle, golf corridor | Seasonal luxury lets where licensed |
| Mijas | 3 | Families, village charm, La Cala beach | Mixed long-let and holiday |
| Estepona | 5 | Value coastal, Selwo golf | Growing marina and old-town demand |
| Fuengirola | 3 | Urban beach, rail link to Málaga | Promenade short-let potential |
| Benalmádena / Vélez | Multiple in full portfolio | Mid-market apartments | Domestic and tourism mix |
Marbella entries in June 2026 span €795,000 sea-view apartments on Roy Boston to a €2.49M duplex overlooking Golf Río Real, illustrating how a single agency desk can span mid-luxury and ultra-prime in one municipality. Fuengirola starts lower at €380,000 for a three-bedroom Los Boliches apartment, attractive to yield-focused buyers comfortable with urban density.
How Alianz compares with listed developers on Invest Spain Property
Developer reviews on this site track one promoter balance sheet; Alianz maps a multi-seller shelf. Use both: developers for guarantee clarity, agencies for resale liquidity and renovated stock.
| Factor | Alianz Group (agency) | Neinor / Insur (developers) |
|---|---|---|
| Legal counterparty | Changes per listing | Single promoting company |
| Deposit protection | Per-seller; off-plan needs aval bancario | Listed developers publish guarantee frameworks |
| Pricing | Fast-moving ask prices | Phase-based price lists |
| Product breadth | Resale, renovated, obra nueva mix | New-build masterplans |
| Best for | Comparison shopping across formats | Buyers wanting one community and build standard |
Cross-read developer stock before you reserve: Grupo Insur on Estepona and Mijas, Neinor Homes on Estepona Bayside, and TM Grupo on eastern Costa comparisons.
Rental outlook when buying through an agency desk
Illustrative gross yields on Costa del Sol depend on licence status, not agency branding. Fuengirola apartments may target holiday lets where community bylaws allow; Marbella ultra-prime stock often blends seasonal and long-let strategies with higher void risk on €2M+ assets.
| Cost line | Typical planning range | Notes |
|---|---|---|
| IBI (annual property tax) | 0.4 to 1.1% of cadastral value | Municipality specific |
| Community fees | €80 to €350 per month | Luxury urbanisations push higher |
| Management | 8 to 25% of gross rent | Long-let vs short-let |
| Non-resident tax | 19 to 24% on net rental | Model with accountant |
Read the Spain rental yield guide and municipality area guides before trusting turnkey rental language on any Alianz listing.
Pros and cons for international buyers
