Cross-border commuter mortgage — CHF income from Switzerland
You live in Germany and work in Switzerland, Austria, Luxembourg, the Netherlands or France. Income is often in a foreign currency — and that is a problem for many banks. I know the banks that handle this actively. This is a non resident mortgage case — financed from Germany, not against it.
In short
Can cross-border commuters finance in Germany?
Yes — financed from Germany, not against it. The issue is foreign-currency income (often CHF); we know the banks that handle this actively. Euro commuters from Luxembourg or Austria are the simplest cases.
What is special about Swiss commuters?
It is the largest commuter market with an established pool of banks. Some lenders do not accept foreign-currency income — others do, and each applies its own safety margin to it. Bank selection matters most.
Can I get a German mortgage as a cross-border commuter?
Yes — as a cross-border commuter who lives in Germany and works in a neighbouring country (Switzerland, Austria, Luxembourg, the Netherlands, France), a German mortgage is very possible; your residence is in Germany after all.
The particularity is the income: it often flows in a foreign currency — typically Swiss francs — and from a foreign employment contract. The bank applies a safety discount to foreign-currency income and scrutinises the foreign contract more closely; some institutions treat CHF income more generously, others more cautiously.
The tax treatment — cross-border commuter rules, withholding tax — also feeds into the paperwork. Anyone who assembles the right proofs early and picks a lender used to commuter income usually finances on regular terms. Which lenders those are, we clarify in conversation. Not legal or tax advice.
Common cross-border commuter profiles
Konstanz · Lörrach · Singen ↔ Zurich · Basel
The largest cross-border market. CHF income, an established pool of banks.
Saarland · Trier ↔ Luxembourg
EUR — no currency issue. The simplest case. LU incomes are often high, which means very good terms.
Bavaria · Vorarlberg border ↔ Austria
EUR, established. The Hochrhein–Vorarlberg commuter case is also well served.
Aachen · Lower Rhine ↔ Netherlands
EUR, straightforward. A Dutch employer with a German residence — many banks underwrite that.
Baden ↔ France
EUR, a small but active market. Saarland ↔ Lorraine also works.
Requirements for the application
- Stable employment with a foreign employer — at least 12 months, ideally longer
- Payslips in the original language + EN/DE translation where needed
- Tax assessment in line with the double-taxation treaty — typically taxation in Germany as the country of residence (CH commuters) or foreign payroll tax (LU commuters)
- SCHUFA from the German residence — should be in place
- Equity similar to a standard mortgage: purchase costs of 8–15 % covered by your own funds, no further equity strictly required
What often makes commuters cheaper to finance
Cross-border commuters are not a classic foreign case — you are resident in Germany, only your job is abroad. That makes it simpler than for Germans living abroad:
- SCHUFA + German credit history fully in place
- KfW funding applies without restriction (resident-taxpayer status)
- The pool of banks is much larger than for non-residents
- The notary appointment in Germany is easy
Swiss commuters: what is special
- CHF income is converted, with a discount of 10–50 %, depending on currency and type of income
- Withholding-tax advance payment via payroll — a German tax assessment is still produced
- The 4.5 % rule on a move across the border — relevant for assessment questions
- Notary in Germany — no dealings with Swiss notaries
