Hidden fees & budget planning for property purchase

Last updated: December 2025 | Originally published June 2025. Key changes: Registration fees returned to standard 7% rate July 1, 2025; Bëllegen Akt for primary residence now permanent at €40,000/person; investor-specific Bëllegen Akt ended December 31, 2024.

Purchasing property in Luxembourg involves far more than just the advertised price. While the Grand Duchy offers excellent investment opportunities and quality of life, buyers often underestimate the additional expenses that can add 10-15% to their total budget. Understanding these hidden costs upfront prevents financial surprises and ensures you can secure your dream property without exceeding your means.

The Luxembourg property market in 2025 continues to offer attractive opportunities, with the permanent Bëllegen Akt tax credit providing substantial support for primary residence buyers. However, successful property acquisition requires comprehensive budget planning that accounts for all associated real estate fees beyond the purchase price.

Notary Fees: The Largest Additional Expense

Notary fees represent the most significant additional cost when buying property in Luxembourg. All real estate transactions must go through a state-appointed notary, making these fees unavoidable. The standard structure includes registration fees of 6% and transcription fees of 1% of the purchase price, totaling 7% of the property value.​

A temporary reduction applied between October 1, 2024, and June 30, 2025, when registration fees were reduced to 3.5%. This measure has expired, and standard 7% rates apply to all purchases from July 1, 2025 onwards. For a €500,000 property purchased in December 2025, registration and transcription fees total €35,000.​

Beyond registration costs, notary emoluments (professional fees) add approximately 1% of the property price. Additional expenses include administrative costs for obtaining cadastral extracts and various administrative documents, typically ranging from €300 to €800 depending on the transaction complexity.

For first-time buyers purchasing their primary residence, the “Bëllegen Akt” tax credit provides significant relief. This credit was made permanent at €40,000 per person (€80,000 for couples) effective July 1, 2025, representing excellent news for Luxembourg homebuyers. This permanent enhancement provides substantial ongoing support for property acquisition.​

Mortgage and Banking Costs

Securing financing involves several hidden costs beyond the interest rate that many buyers overlook. Banks typically charge application fees ranging from €250 to €1,000, plus property appraisal costs of €300 to €500. These upfront expenses are required regardless of whether your mortgage application succeeds.

Outstanding balance insurance represents another significant ongoing cost. This insurance, generally required by lending institutions, can cost several hundred euros monthly. The charges are calculated as a percentage of your loan amount, and given Luxembourg’s high property values, these contributions are mechanically higher than in other countries.

Mortgage registration fees also apply when the bank takes a mortgage on the property as security. For a €400,000 property, mortgage costs including registration and recording costs plus notary fees amount to approximately €2,700. If you sell the property before the mortgage term ends, additional hidden fees apply for lifting the mortgage.

Understanding your complete financing picture is crucial, which is why our financing and mortgage guide for property buyers provides comprehensive insights into securing the best terms and managing all associated real estate fees.

Real Estate Agent Commissions

While sellers typically hire real estate agents in Luxembourg, buyers often bear this cost indirectly through higher sale prices. Standard commission rates are 3% of the sale price plus 16% VAT. For a €600,000 property, this represents approximately €20,880 in total commission costs—a significant hidden cost in the transaction.

Some buyers choose to work directly with developers or private sellers to avoid these fees, though this approach requires more personal involvement in the transaction process. When deciding whether to sell privately or with a real estate agent, consider both the cost savings and the professional expertise that agents provide.

Property Surveys and Technical Inspections

Though not mandatory in Luxembourg, technical surveys are highly recommended, particularly for older properties. These inspections cost between €500 and €1,200 but can prevent costly surprises after purchase—making them worthwhile despite being hidden fees that buyers sometimes overlook. Surveys typically examine structural integrity, electrical and plumbing systems, roof condition, windows, and potential issues like mold or inadequate insulation.

For buyers considering older properties, these inspections become even more critical. Our guide on old property renovation versus new construction explores how survey findings can inform renovation budgets and help negotiate purchase prices based on identified issues.

Additional Hidden Costs to Consider

Several other hidden fees can impact your budget significantly. Property insurance is essential and costs vary based on property value, location, and coverage level. Annual premiums typically range from €800 to €2,000 for standard residential properties.

Moving costs often exceed expectations, particularly for international relocations. Professional moving services within Luxembourg cost €1,000 to €3,000, while international moves can reach €5,000 or more depending on distance and volume—hidden costs that buyers frequently underestimate.

Utility connections and deposits may be required for electricity, gas, water, and internet services. While individual deposits are modest, collectively they can total €500 to €1,000 in often-overlooked hidden fees.

Property taxes apply annually and vary by commune. While Luxembourg’s property taxes are relatively low compared to other European countries, they should be factored into long-term ownership costs.

Investment Property Considerations

Investors should note that the “Bëllegen Akt Investisseurs” tax credit that provided up to €20,000 per person in notary fee reductions for VEFA (future state of completion) rental investments ended on December 31, 2024, and is no longer available.​

Investment properties purchased under qualifying programs may still qualify for accelerated depreciation benefits, though specific measures and eligibility should be verified with tax professionals as several programs ended in 2025.

For those considering rental properties, understanding lease contracts and tenant rights helps ensure compliance with Luxembourg’s rental regulations and proper budget planning for landlord responsibilities.

Budgeting Strategies and Timeline Planning

Effective budget planning requires adding 10-15% to the property purchase price to cover all additional real estate fees and hidden costs. For a €500,000 property purchased in December 2025, budget an additional €50,000 to €75,000 for fees, inspections, insurance, and moving costs.

Key cost example for December 2025:

• Purchase price: €500,000
• Registration + transcription fees (7%): €35,000
• Less: Bëllegen Akt credit for couple: -€80,000
• Net registration payment: €0 (credit exceeds fees)
• Notary emoluments (~1%): €5,000
• Mortgage costs: €2,500-€3,000
• Survey/inspection: €800
• Insurance, moving, utilities: €3,000-€5,000
• Total additional costs: ~€11,000-€14,000 (after Bëllegen Akt credit)

The permanent Bëllegen Akt tax credit of €40,000 per person (€80,000 for couples) now provides ongoing support for primary residence buyers, making Luxembourg property acquisition more accessible without time pressure from expiring measures.​
