Key Tax and Due-Diligence Issues for Buying Property in Courchevel

What strikes me most about the French Alps market—and Courchevel specifically—is how international buyers assume the notaire handles everything. To be blunt, that’s your first mistake. The notaire secures the legal transfer, yes. But they won’t tell you whether your rental strategy makes sense or warn you that the building’s reserve fund is empty.

In my practice, the files that go smoothly share one trait: buyers who asked uncomfortable questions early. Not after the compromis is signed. Not when the bank requests more documents. But during those first viewings when everyone’s still talking about the view from the balcony.

What “due diligence” really means in a French resort purchase

Here’s what nobody tells you: due diligence in France isn’t about finding problems—it’s about understanding which problems you can live with. Every Courchevel property has quirks. Some have servitudes (easements) dating back to 1847. Others sit in co-ownerships where half the owners live in Dubai and never vote. The question isn’t whether issues exist. It’s whether you’ve spotted them before signing.

The French system splits verification across multiple actors. Your real estate agent in Courchevel shows properties and might flag obvious issues. The notaire handles the legal mechanics and collects mandatory annexes. But between these two poles lies a gap—the strategic analysis of what these documents mean for your specific situation. That’s where most buyers get caught.

Last Tuesday, I was reviewing files with Omar, an entrepreneur looking at Courchevel 1550. He’d budgeted perfectly for the purchase price. What he hadn’t seen coming? The co-ownership had voted €180,000 of facade works, with his share at €22,000 due within six months. The syndic had sent those AGM minutes late—a classic move—and his bank started asking questions the same week. We salvaged the deal, but only after renegotiating terms.

The notaire’s role is narrower than you think. They verify legal title, ensure taxes are paid, and register the transfer. They check that mandatory diagnostics exist. But they won’t analyze whether the DPE energy rating will affect your rental income, or whether the co-ownership rules actually allow short-term letting. These aren’t legal defects—they’re commercial realities that can torpedo your investment thesis.

In ski resort purchases, three document categories matter most: title and servitudes (what you actually own), co-ownership papers (your ongoing obligations), and diagnostics (the property’s physical condition). Each tells a different story, and you need all three stories to align with your plans.

The due-diligence pack: what to request and how to read it (in order)

When I coach buyers through their first French purchase, I tell them to think of documents like an avalanche assessment—you check multiple layers because any single weak point can trigger problems later. The mistake I see constantly? Reading documents in random order, or worse, assuming the six-page compromis summary captures everything important.

Title, boundaries, servitudes: what can’t be ‘fixed later’

Start with the titre de propriété (title deed) and any servitude documentation. These are immutable—once you buy, you inherit whatever’s written there. I recently reviewed a chalet where the seller had “forgotten” to mention a public footpath servitude crossing the garden. Legally perfect, commercially disastrous for the buyer’s privacy expectations. These documents often reference cadastral plots that don’t match current reality, especially in old resort areas where properties have been split and merged over decades.

The hypothèque (mortgage registry) search reveals more than debts. It shows historical transactions, which helps spot patterns. If a property has changed hands three times in five years, that’s worth investigating. Sometimes it’s innocent—international postings, divorces—but occasionally it signals issues with the building or location that only become apparent after living there.

Co-ownership (copropriété): minutes, works, rules, and cash calls

This is where deals die or thrive. Request three years of AG (assemblée générale) minutes, not just the latest one. The patterns matter more than single decisions. Are the same five owners voting everything down? Has the syndic changed twice? These minutes reveal the building’s governance health.

In my experience reviewing files, buildings with over 40% non-resident owners tend toward two extremes: either professionally managed with clear processes, or chronically deadlocked on maintenance decisions. The PV (procès-verbal) will tell you which type you’re entering. Look specifically for any mention of “travaux votés” (voted works) and “appels de fonds exceptionnels” (special assessments). That façade renovation might be “planned for 2028” but if it’s voted, you’re committed.

The règlement de copropriété isn’t bedtime reading, but articles about “destination de l’immeuble” and “location” are non-negotiable checks. Some Courchevel buildings explicitly prohibit short-term rentals. Others allow it but with restrictions that kill profitability—mandatory key handover to the syndic, exclusive use of building’s rental pool, or quiet periods during owner seasons.

Mandatory diagnostics: what they prove—and what they don’t

French law mandates several diagnostics depending on the property’s age and location. The DPE (energy performance) lasts 10 years and affects both value and rentability. Asbestos checks are required if the building permit predates July 1997—critical in many Courchevel properties from the 1970s-80s boom. Lead paint applies to pre-1949 construction.

But here’s what catches buyers: diagnostics confirm presence or absence, not fitness for purpose. An asbestos report might say “present but contained”—technically fine for sale, potentially problematic for your renovation plans. The electrical diagnostic checks safety, not capacity. That 1980s electrical panel might pass but won’t support your planned hot tub and Tesla charger.

Taxes you can’t ignore: purchase, ownership, resale (non-resident lens)

Let’s address the expensive elephant in the room: French property taxes aren’t simple, and being non-resident adds layers. But once mapped correctly, they’re predictable. The surprise isn’t the rates—it’s discovering obligations you didn’t know existed.

I’ll never forget Sophie, a consultant I advised before her Courchevel 1850 purchase. She’d assumed “taxes are the same for everyone” and hadn’t mapped the implications of second home versus rental property. After conflicting advice from two sources, we needed a three-way call between her, the notaire, and a tax adviser. She proceeded, but only after documenting her intended use pattern—critical for tax treatment.

At purchase: duties, notarial costs, and what’s actually included

Transfer taxes hit immediately. According to 2025 rates, departments can charge between 3.8% and 5% in transfer duties. Savoie currently applies 4.5%, but this can change—30 departments have already announced increases through April 2028. Add notaire fees (roughly 1-1.5% on properties above €500,000), plus registration and administrative costs, and you’re looking at 7-8% total acquisition costs on existing properties.

New builds operate differently: VAT at 20% is included in the price, but transfer duties drop to around 0.7%. If you’re buying off-plan in a new Courchevel development, this structure might save money upfront, though new builds typically command premium prices that offset tax advantages.

While owning: local taxes, wealth tax exposure, and rental income basics

Annual holding costs extend beyond the obvious taxe foncière (property tax based on cadastral value). The elephant in many international buyers’ rooms is the IFI (Impôt sur la Fortune Immobilière). According to official IFI thresholds, if your net worldwide property exceeds €1.3 million, you’re liable—regardless of residency. That Courchevel apartment plus your London home might trigger obligations you hadn’t considered.

Rental income taxation depends on your regime choice and residency status. Non-residents face a minimum 20% withholding (30% above certain thresholds), though tax treaties may reduce the final burden. The complexity isn’t the rate—it’s understanding which income must be declared where, and when treaty benefits apply versus when they don’t.

At resale: capital gains logic, reporting, and common misconceptions

French capital gains tax on property operates on a sliding scale with duration. The headline rate for non-residents starts at 19% (plus social charges), but temporary non-resident withholding reaches 36.2%. You’ll need to file for refunds if treaties reduce your actual liability—a process that takes months, not weeks.

The key insight many miss: allowances for improvements require French invoices from registered contractors. That beautiful renovation using British builders paid in pounds? Might not qualify for capital gains deductions. Document everything from day one with French fiscal compliance in mind.

In the files I review, tax surprises rarely come from rates being higher than expected. They come from obligations nobody mentioned—quarterly advances, reporting deadlines that don’t align with your home country’s tax year, or discovering that your ownership structure triggers different rules than anticipated. This is precisely where understanding the French real estate tax framework becomes essential for foreign buyers.

How buyers structure the purchase (and when to bring in a tax adviser)

Should you buy personally or through a structure? In my experience, this question arrives too late—usually after the compromis is drafted. The correct time is before you make your first offer, because structure affects everything: financing options, tax treatment, succession planning, and exit flexibility.

Personal ownership is simpler and often cheaper initially. You buy, you own, you sell. But for non-residents with substantial wealth or complex family situations, structures like an SCI (Société Civile Immobilière) might offer advantages. The catch? These structures require ongoing compliance, French accounting, and can complicate financing. Banks often demand personal guarantees anyway, negating some theoretical protections.

The notaire handles conveyancing but won’t advise on optimal structures—that’s explicitly outside their remit. They’ll execute whatever structure you choose, but choosing requires specialized tax counsel. This division of responsibilities catches many international buyers who expect comprehensive advice from a single source.

Here’s my practical breakdown: if your situation involves any of these elements, engage a tax adviser before signing anything: non-resident status with treaty considerations, property value exceeding €2 million, intended rental income exceeding €30,000 annually, multiple beneficiaries or complex succession plans, or existing structures in other countries that might interact with French ownership.

A realistic signing timeline (and where delays usually happen)

• Day 0-7
  Offer accepted → Begin KYC/funds documentation for bank and notaire
• Day 7-21
  Compromis drafting + annexe collection (diagnostics often cause first delays here)
• Day 21-45
  Buyer clarifications + mortgage approval (non-resident loans regularly add 3 weeks)
• Day 60-120
  Acte authentique preparation and signing (pre-emption checks, final funds transfer verification)

The financing element deserves special mention. French banks remain conservative with non-resident lending—expect 30-40% minimum deposits and extensive income documentation. The funds origin paperwork has become particularly stringent. That inheritance from 2018? You’ll need the will, probate documents, and bank statements showing the trail. Sold a business? Prepare share purchase agreements and completion statements.

The broader economic context also matters for timing your entry. To understand how fiscal policy shapes real estate markets, particularly in luxury resort destinations like Courchevel, helps explain why certain periods offer better opportunities than others.

The questions buyers keep asking before they sign in Courchevel

After years of fielding panicked calls, I’ve noticed the same anxieties surface repeatedly. These aren’t theoretical concerns—they’re the 2 AM doubts that make buyers reconsider everything. Let me address them plainly.

Your next moves before making an offer

Rather than conclude with platitudes about the French Alps property market, let me leave you with a question that separates successful purchases from problematic ones: Have you written down—explicitly—what success looks like for this property in year three? Not just financially, but practically. How often will you actually use it? Who manages it when you’re away? What happens if rental rules change?

The buyers who answer these questions before viewing properties are the ones calling me two years later about their next investment. The ones who don’t are usually calling about exit strategies and tax surprises. In Courchevel’s market, preparation isn’t just helpful—it’s the difference between owning a dream property and managing an expensive problem.
