15 Mistakes That Cost Property Sellers Money in Luxembourg

Introduction

Selling a property in Luxembourg is a major financial operation. The median apartment price reaches €750,000 and houses exceed €1,100,000. At these amounts, the slightest mistake can cost tens of thousands of euros.

Mistake 1: Overpricing the Property

This is the number one mistake in Luxembourg. Sellers overprice their property by 10 to 20% on average. The result: the property stays on the market too long and ends up selling below its actual value.

Solution: Get your property valued by at least 3 independent sources. Use the Sellect.lu valuation tool as a starting point.

Mistake 2: Underestimating Selling Timelines

The average selling time in Luxembourg is 90 to 120 days.

Mistake 3: Neglecting Property Presentation

First impressions count. A poorly maintained property immediately loses potential buyers.

Mistake 4: Choosing the Wrong Agency

Not all agencies are equal. Check our 10 agency selection criteria before signing.

Mistake 5: Not Comparing Agencies

Compare at least 3 agencies on Sellect.lu.

Mistake 6: Signing a Long Exclusive Mandate

Prefer a mandate of 3 months maximum, renewable, with a clear exit clause.

Mistake 7: Ignoring Legal Requirements

Luxembourg requires several mandatory documents for selling.

Mistake 8: Neglecting the Energy Certificate

The EPC has been mandatory since 2010. A poor rating can reduce the price by 10 to 25%.

Mistake 9: Forgetting Capital Gains Tax

If you sell less than 2 years after purchase, gains are taxed at progressive rates (up to 42%).

Mistake 10: Refusing All Negotiation

In Luxembourg, the average negotiation margin is 3 to 7%.

Mistake 11: Conducting Viewings Yourself

Sellers are emotionally attached. Let a professional handle viewings.

Mistake 12: Accepting an Offer Without Financial Proof

Require a bank pre-approval before accepting any offer.

Mistake 13: Selling at the Wrong Time

Spring (March-June) is traditionally the best time to sell.

Mistake 14: Hiding Defects

In Luxembourg, the hidden defects guarantee applies up to 2 years after sale.

Mistake 15: Not Planning for Seller Costs

Don't forget your own costs: notary fees, early loan repayment, diagnostics, agency commission.
