Non-resident mortgage in Luxembourg: CSSF limits, costs and banks

Getting a non-resident mortgage in Luxembourg while living elsewhere

A large share of Luxembourg’s workforce commutes daily from France, Belgium and Germany. Many of these frontaliers eventually consider buying in the Grand Duchy, either to move closer to work or to hold a rental flat, while still being non-residents when they apply.

A second group consists of investors and expatriates living further away who want a foothold in a stable, high-income market. Their applications are examined more cautiously, because the bank has less visibility on foreign income and on assets held outside Luxembourg.

No nationality restriction on ownership

Luxembourg does not limit property purchases by foreigners or non-residents, so a non-resident mortgage loan raises no ownership question. The deed for a non-resident home loan in Luxembourg is signed before a Luxembourg notary, who registers the transfer and the mortgage. Hurdles for outsiders therefore come from bank credit policies, not from an authorisation regime like those seen elsewhere.

Why the income source outweighs residence

For a mortgage for non-residents, banks mainly ask whether income is stable, verifiable and in euros. A permanent contract with a Luxembourg employer reassures them, even if the borrower sleeps in Thionville or Arlon. Self-employed applicants abroad or those paid in other currencies usually face larger deposit requirements.

Banks that publish mortgage documentation

Spuerkeess, the state savings bank, BIL, Raiffeisen and the large international groups present in Luxembourg all publish information on their housing loans. Whether a specific non-resident profile qualifies is decided case by case, so apply to several lenders in parallel.

Loan-to-value limits set by the CSSF

Since January 2021 a CSSF regulation caps loan-to-value ratios for mortgages on Luxembourg residential property. The ceilings differ by buyer profile, as shown below; lenders may apply stricter internal limits, especially for applicants with foreign income or no Luxembourg banking history.

A non-resident who buys a flat to rent out falls into the last category. In practice that means contributing at least a fifth of the price plus acquisition costs from personal savings, and some banks ask more from borrowers whose income is earned abroad.

Acquisition costs to budget

In standard cases registration and transcription duties total seven per cent of the price, before notary and mortgage-registration fees. The Bëllegen Akt tax credit reduces these duties only for buyers who will occupy the home as their main residence, which excludes most non-resident investors.

Interest-rate context in 2026

After the sharp rise of 2022 and 2023, fixed-rate offers in Luxembourg eased and then levelled off, according to local market reporting. Rates vary by bank, term and profile, so compare written offers rather than relying on advertised examples or averages.

Tax angle for cross-border workers

Non-residents taxed in Luxembourg may, under conditions, opt to be treated like residents and deduct certain interest. The rules depend on the share of income earned in Luxembourg and on tax treaties, so check with a tax adviser before counting on any deduction.

Documents and application process for a non-resident home loan in Luxembourg

Luxembourg lenders assess every non-resident mortgage in Luxembourg file with the same standards as resident ones, but they expect complete paperwork in one go. Missing foreign tax documents are the most frequent cause of delay, particularly for applicants whose household income is partly earned outside the Grand Duchy.

Documents usually requested

For a non-resident home loan in Luxembourg, prepare identity documents, the employment contract, the last three payslips, recent tax returns from your country of residence, bank statements showing savings for the deposit, the signed preliminary sale agreement (compromis de vente) and details of any existing loans, including those held abroad.

Step-by-step path to a Luxembourg mortgage

1. Calculate your deposit using the CSSF ceiling that matches your profile, then add roughly seven per cent for duties and notary fees.
2. Request an indicative financing agreement from two or three banks before signing a compromis.
3. Confirm that each lender appears in the CSSF list of authorised credit institutions.
4. Sign the compromis with a financing condition and send the complete file to the chosen banks.
5. Compare binding offers, including insurance costs, rate type and early-repayment terms.
6. Sign the deed and mortgage before the notary, who registers both.

Insurance and guarantees

Banks generally require a mortgage registered on the property, fire and home insurance and, in most cases, outstanding-balance life cover. Non-residents can often use a foreign insurer if the policy meets the bank’s conditions, which may lower premiums for some applicants.

Pitfalls of a mortgage for non-residents

Most failed projects stem from underestimating the cash needed, from income the bank cannot verify, or from dealing with unregulated intermediaries. These are the points to check before committing to a purchase in the Grand Duchy:

• Signing a compromis without a financing condition, then losing the deposit when the bank applies a stricter LTV than expected.
• Assuming the Bëllegen Akt applies to a flat bought for letting.
• Overlooking the currency risk when income is earned in sterling, Swiss francs or dollars while the loan is in euros.
• Paying an upfront fee to an online “Luxembourg mortgage broker” that promises approval before any file review and is not authorised by the CSSF: genuine banks never collect such advance fees.
• Forgetting that a foreign lender in your home country may refuse to take security over Luxembourg property.

Can a cross-border worker living in France borrow from a Luxembourg bank?

Yes, this is common. Luxembourg banks know the frontalier profile well and are generally comfortable with a Luxembourg salary. For property located in France, however, many prefer that the loan is arranged with a French lender familiar with French guarantees.

Can someone living outside the EU obtain a Luxembourg mortgage?

It is possible but less frequent. Expect a larger deposit, detailed evidence of foreign income and assets, possibly a requirement to place savings with the lender, and enhanced anti-money-laundering checks. Some banks decline residents of certain countries for compliance reasons.

Are loans available in currencies other than the euro?

Residential mortgages on Luxembourg property are almost always granted in euros. Borrowers paid in another currency should model repayments under adverse exchange-rate scenarios and keep a buffer, because a weaker home currency increases the effective monthly cost.

Should a broker be used?

A broker can save time by approaching several banks, but should be properly authorised. Ask for the CSSF registration or an EU passport for mortgage intermediation, a written fee agreement, and confirmation that remuneration is only due once a loan offer is signed.
