Real Estate Transfer in Switzerland: Taking Over Your Parents’ Mortgage – What You Need to Know

Transferring homeownership within a family is a significant step both emotionally and financially. Whether through an advance inheritance, a gift, or a sale: anyone taking over a property from their parents faces a wide range of legal, tax, and financing questions. One key issue is how to handle the existing mortgage. Can it be taken over, or does a new one need to be arranged?

In this post, we’ll explore the key aspects of mortgage assumption in Switzerland and show you how to plan the property transfer effectively.

Taking Over a Mortgage: Is It Even Possible?

In Switzerland, a mortgage is legally linked to the property, but it cannot automatically be transferred to a new owner. Banks are required to reassess the mortgage’s affordability in the event of a change in ownership. They review the following in particular:

• Income and assets of the new owners

• Equity ratio (at least 20% of the property’s value, with at least 10% from non-pension funds)

• Existing debts and financial obligations

• Future maintenance and investment costs for the property

Conclusion: A mortgage can only be assumed with the bank’s explicit approval. This can be worthwhile if the existing conditions are attractive. Alternatively, a new financing solution may be chosen but this can incur costs, especially if a fixed-rate mortgage is terminated early (known as a prepayment penalty).

Models of Property Transfer: What Are the Options in Switzerland?

In Switzerland, there are several common models for transferring homeownership within a family, each with specific legal and tax implications:

1. Gift With or Without Usufruct/Right of Residence

Parents transfer ownership free of charge, often while retaining a lifelong right of residence or usufruct. Important: These servitudes reduce the taxable market value, which affects equity requirements and financing. For more on usufruct, rights of residence, and the legal framework, see the PostFinance blog post on servitudes.

2. Advance Inheritance

A property is transferred to a child during the parents’ lifetime and later offset against their inheritance share. Mandatory shares and equalization obligations for siblings must be respected. A clear arrangement in a will or inheritance contract is essential.

3. Mixed Gift

Part of the value is gifted, and the rest is paid through a symbolic or reduced purchase price. This is often used when the child has already invested in the property or when parents seek financial security.

4. Sale Among Relatives

A standard sale at a market or discounted price. The heirs assume the mortgage, taxes, and maintenance duties. A professional purchase agreement is recommended, including clear terms for repurchase rights, rights of first refusal, or profit-sharing in case of future resale.

Tax and Legal Particularities in Switzerland

Tax and fees vary by canton in Switzerland. Key points include:

• Gift and Inheritance Taxes: Transfers to direct descendants are usually tax-free, but exceptions exist (e.g., in patchwork families or transfers to in-laws).

• Property Transfer Taxes: Some cantons (e.g., Zurich) do not impose them, while others (e.g., Bern, Vaud) do. Family transfers may be exempt depending on the canton.

• Land Registry Fees: These always apply even when there is no payment involved.

Ensuring Long-Term Affordability

Whether an existing mortgage is assumed or a new one is arranged, it’s essential that the financing remains sustainable in the long term. Banks typically calculate affordability based on a hypothetical interest rate of 5%, plus maintenance and ancillary costs. A rule of thumb: Annual housing costs should not exceed one-third of gross income.

Future homeowners should consider the following:

• Will investments be needed for the property?

• Are there any expected changes in income?

• Can future interest rate fluctuations be managed?

• How should a future sale or inheritance division be handled?
