First and Second Mortgages
Explained Simply

The terms and are among the fundamentals of in Switzerland. Even though many today only report a single aggregate Mortgage, internally they almost always still calculate using this breakdown.

The following text discusses the “rules” for owner-occupied properties.

First and second mortgages

Explanation
What are first and second mortgages?

The distinction is based on the

  • 1. Mortgage: up to approx. 65% of the property value 
  • 2. Mortgage: from 65% to a maximum of 80% 

The higher the Loan-to-value ratio, the higher the risk for the mortgage lender. Mortgage lenders calculate the value of the property in different ways. Some are more stringent or use different tools to appraise the property. The amounts of the first and second mortgages therefore vary from provider to provider.

Long-term and stable
The 1st Mortgage

A first Mortgage is considered very secure because it is backed by a large portion of the property’s value.

Features
  • Loan-to-value ratio of up to approx. 65% of the property value
  • No
  • often structured for the long term (possible even beyond retirement) 
  • usually a lower interest rate 

For mortgage lenders, this segment is particularly low-risk. There are mortgage lenders, such as that only grant mortgages with a Loan-to-value ratio of up to 65% or 70%. For this reason, those with only a first Mortgage can often benefit from particularly favorable terms.

Higher Risk, Clear Rules
The Second Mortgage

The second mortgage covers the portion of the Loan-to-value ratio above 65%.

Features
  • Loan-to-value ratio ranging from 65% to, in most cases, a maximum of 80% of the property value 
  • must be amortized (usually within 15 years or until retirement). Amortization can be done directly or indirectly.
  • Higher risk for the bank 
  • often a higher interest rate 

The reason for the increased risk: In the event of a foreclosure, the first Mortgage is repaid first. The second Mortgage is only repaid if the proceeds from the sale of the property are sufficient to cover it (first- and second-priority Borrower's notes).

How much down payment do I need?

When purchasing a property, the general rule is: at least 20% of which at least 10% —that is, excluding pension fund assets.

Equity includes
  • Savings and account balances 
  • Securities 
  • Pillar 3a 
  • Gifts or advance inheritance 
  • Pension fund (restricted) 
  • Personal contributions or Lot

Funds from the 2nd pillar may be used in full as own funds until age 50. Starting at age 50, withdrawals are limited: You may withdraw either the amount you had at age 50 or half of your current pension fund assets, whichever is greater.

The higher amount applies. You can find out how much money you have saved in your pension fund directly from your pension fund or on your current pension fund statement. Many pension funds indicate on the pension fund statement the maximum possible amount available for home ownership (WEF withdrawal).

Why are there first and second mortgages in the first place?

This classification is primarily used for risk assessment: A low Loan-to-value ratio means low risk and results in better terms. A high Loan-to-value ratio entails higher risk, stricter rules, and less favorable Mortgage terms.

A first-lien mortgage is always repaid before a second-lien mortgage if the property is sold (foreclosed). The priority of the mortgages is bindingly recorded in the Land registry. A second-lien mortgage therefore carries significantly greater risks for the mortgage lender than a first-lien mortgage.

If the entire mortgage is held by the same mortgage lender, a consolidated statement is usually prepared to assess risks and margins. In practice, however, mortgages can also be split among multiple mortgage lenders. In this case, the mortgage’s priority ranking is crucial.

Frequently Asked Questions
Answers about first and second mortgages

Within 15 years or until retirement (whichever comes first). This applies to owner-occupied residential property. Different guidelines apply to investment properties.

Weil sie für die Bank ein höheres Risiko darstellt. Sie steht im zweiten Rang und wird im Risikofall erst zurückbezahlt, wenn die Schuld aus der ersten Hypothek vollständig getilgt ist. Deshalb ist der Zinssatz der zweiten Hypothek höher. Risiken aktiv zu steuern ist gerade bei der Ratingoptimierung bei der Hypothek ein wichtiges Thema.

A second mortgage can only be increased if the property value has risen and the borrower still meets the Affordability requirements.

A mortgage increase is always reviewed on a case-by-case basis by the mortgage lender. In practice, it is not uncommon for the mortgage lender to block an increase in the second mortgage, even if Affordability and the “new” Loan-to-value ratio would be within acceptable limits based on the numbers alone. Each case is evaluated individually. 

An important point: Not every evaluates things the same way. Differences exist in Valuation—Purchase price versus appraised value—affordability calculations, maximum Loan-to-value ratios, and how income and assets are handled.

In practice, this can lead to significant differences: For the same property, one provider may offer a maximum Mortgage of 700,000 francs, while another may finance up to 850,000 francs.

The difference often lies in the assessment and calculation methods. Some mortgage lenders are deliberately stricter, while others are willing to take on “less favorable” deals. 

Conclusion
Understanding Leads to Better Decisions

Even though these terms are less commonly used today, first and second mortgages remain central to:

  • Loan-to-value ratio 
  • Risk 
  • Amortization 
  • Financing Options
  • Mortgage Interest Rate

If you understand the differences, you can optimize your financing strategy and compare better offers. Ask your mortgage lender what the Loan-to-value ratio is and at what value you can expect better interest rates. This is part of the for better interest rates.
