The building blocks of homeownership financing
The dream of owning your own home starts with the right financing. Two building blocks are crucial here: Equity and a mortgage, which together form the financial foundation for your home. Ongoing costs also play a decisive role in ensuring that the financing continues to work in the long term:
- Interest on the mortgage
- Amortization (repayment of the 2nd mortgage)
- Ancillary costs for maintenance and use
These ongoing costs must be permanently covered by your income – that is the core principle to ensure affordability.
A simple rule of thumb
Your housing costs should not exceed one third of your gross income.
Equity: The foundation for the home of your dreams
When buying a property, banks and insurance companies generally require buyers to contribute at least 20% of the purchase price themselves. This equity can come from savings, securities, gifts or pillar 3a. If you want to use funds from a pension fund, you have two options:
- Early withdrawal: The capital is withdrawn directly and used as equity. However, this reduces the retirement pension and the insurance benefits.
- Pledging: The money remains in the pension fund, but serves as security. This allows you to take out a higher mortgage without reducing your pension benefits.
You should carefully consider which option suits you best – including with regard to your retirement provision.
Please note that additional notary fees and transfer taxes are payable on the purchase, which cannot be covered by the 20% equity. It is therefore worth planning a reserve to prevent financial shortfalls.

Good to know
You will find the maximum possible early withdrawal for homeownership on your pension fund certificate. There you can see at a glance how much capital you could use to buy a property.
Mortgage: A loan for purchasing your own home
Buyers finance the majority of the purchase price via a mortgage – i.e. a loan that is secured against the property itself. In Switzerland, banks finance a maximum of 80% of the purchase price.
This mortgage is divided into two parts:
- 1st mortgage: Covers around 65% of the purchase price.
- 2nd mortgage: Covers the amount between 65% and 80%. This must be repaid within 15 years or by the time you retire.
This split ensures that debt decreases over the years and that financing remains affordable in the long term.
Mortgage models in comparison
Not every mortgage works the same. You can choose between different models – and combine them to suit your personal goals and wishes:
- Fixed-rate mortgage: The interest rate remains the same for several years. This creates planning security, but is less flexible if interest rates fall.
- SARON mortgage: The interest rate is adjusted regularly and is based on the money market. With low interest rates, it is favorable, but there is a risk of rising costs.
- Variable-rate mortgage: Here, the interest rate is constantly adjusted to the market situation. It is very flexible, but usually more expensive than other models.

Your path to the right mortgage model
Which solution is right for you depends on your personal situation and your need for security. The following questions can help you decide on the right mortgage model:
- Will I sleep better if I know my fixed costs in the long term?
- Do I have reserves to bridge a period of higher costs?
- How flexible am I in adapting my plans if the framework conditions change?

Your house is more than just a piece of real estate – it is your home and an important part of your future. To ensure that financing works today, and remains stable in the coming years, it is worth thinking about additional protection.
