Alex Thornbury

Alex Thornbury is a property analyst and writer on European luxury property. He has spent fifteen years advising international families on cross-border property decisions in Spain, Andorra, Monaco and the wider Mediterranean.

His work sits at the intersection of valuation, transaction structuring and residency planning. The brief he gets from clients is rarely 'find me a villa'. It is usually 'model the ten-year cost of ownership across three jurisdictions, factor in succession exposure, tell me where the lifestyle works for my family, and recommend the hotel where I should base myself for the first two weeks'.

He works independently. He is not affiliated with any property agency, brokerage, or sales platform, and has never been employed by a named global consultancy. He cites Knight Frank, Savills, Spear's and the FT as published data sources only.

He is based in London and spends roughly a third of each year in Palma, Marbella and Andorra la Vella, with regular trips into Monaco.

Areas of work

Alex's work spans the cross-border decisions that determine whether a European property purchase compounds into a tax-efficient base or becomes an expensive lifestyle accessory:

• European luxury real estate
• Tax residency
• Cross-border taxation
• Spain property market
• Andorra residency
• Monaco residency
• Beckham Law
• Inheritance tax planning
• Mediterranean property
• Family office property strategy

Independence

Alex works independently. He is not affiliated with any property agency, brokerage or sales platform, and has never been employed by a named global consultancy firm. Where his work cites Knight Frank, Savills, Spear's, the Financial Times or any other published market source, those firms appear as data sources only. The independence is the editorial position. The reader gets the honest read.

The book

Alex's first book, Quiet Capitals: The Insider's Guide to Property, Residency and Luxury Living in Spain, Andorra and Monaco, is a 315-page comparative briefing on the three quiet European jurisdictions that materially reward the right kind of relocator and penalise the wrong kind.

Method

The writing draws on fifteen years of direct work with international families on cross-border property decisions, supplemented by primary research with notaries, registered tax advisers and family-office staff in each jurisdiction. Published market data from Knight Frank, Savills, Spear's, the Financial Times, the IMSEE in Monaco and national-authority sources in Spain and Andorra is cross-referenced. Where the public sources and the practitioner accounts diverge, the practitioner version typically wins.
