Can Non-Residents Obtain a Swiss Mortgage?

Can non-residents get a Swiss mortgage?

Yes — non-residents can obtain a Swiss mortgage to finance the purchase of a holiday home in Montreux, subject to meeting the bank's eligibility criteria. However, not all Swiss banks offer mortgages to non-residents, and those that do apply stricter conditions than for resident borrowers.

The banks most likely to offer mortgages to non-residents are Swiss private banks and the major international banks with Swiss operations. These institutions are experienced in assessing international income sources and are set up to handle the documentation requirements for non-resident borrowers.

Typical conditions for non-resident mortgages

Non-resident buyers should expect the following conditions: a maximum LTV of 60 to 70 percent of the bank's property valuation (compared to 80 percent for Swiss residents); a minimum equity contribution of 30 to 40 percent of the purchase price; a higher notional interest rate in the affordability test (sometimes 5.5 to 6 percent rather than the standard 5 percent); and more extensive income and asset documentation requirements.

Some banks also require non-resident borrowers to maintain a banking relationship with the bank — holding assets under management or a current account — as a condition of the mortgage.

The Lex Koller connection

Non-resident foreign buyers purchasing a holiday home in Montreux require a Lex Koller authorisation. The bank will require evidence that the Lex Koller authorisation has been granted (or is in the process of being granted) before finalising the mortgage. The mortgage offer is typically conditional on the Lex Koller authorisation being received.

The Lex Koller authorisation process takes 4 to 8 weeks, which must be factored into the overall transaction timeline. Buyers should begin the Lex Koller application as early as possible — ideally before or immediately after the reservation agreement is signed.

Practical steps

Non-resident buyers seeking a Swiss mortgage should: engage a mortgage broker who specialises in international clients before beginning their property search; prepare comprehensive income and asset documentation in advance; obtain a mortgage pre-approval or indicative offer before making an offer on a property; and factor the Lex Koller timeline into the overall purchase timeline.

A mortgage pre-approval demonstrates to sellers that the buyer is financially prepared and serious — an important advantage in the competitive Montreux market.
