Swiss mortgage financing follows three clearly defined basic rules. Anyone who understands equity, loan-to-value, and amortization knows the entire foundation \u2014 and can speak with the bank and the broker on equal footing.<\/p>\n\n\n
In Switzerland, banks finance a maximum of 80 percent of a property’s value through a mortgage. Buyers must contribute the remaining 20 percent as equity. Of that, at most half may come from the pension fund or Pillar 3a \u2014 a minimum of 10 percent in hard equity outside of retirement savings is mandatory.<\/p>\n\n\n
Loan-to-value is the ratio between the mortgage and the property’s value. With a purchase price of CHF 1,000,000 and a mortgage of CHF 800,000, the loan-to-value is 80 percent. Within that 80 percent, banks distinguish between a first mortgage (up to 65 percent loan-to-value) and a second mortgage (from 65 to 80 percent), which must be amortized without exception.<\/p>\n\n\n
The second mortgage (15 percent of the property’s value) must be paid down to 65 percent loan-to-value within 15 years or by retirement \u2014 whichever comes first. Two paths are available for this: direct amortization (annual repayment to the bank) or indirect amortization (payments into a Pillar 3a account, which later pays off the second mortgage).<\/p>\n\n\n
Direct amortization immediately reduces the debt and interest burden. Until 2028, it is less tax-attractive than the indirect variant, because it reduces debt interest deductions. With the abolition of imputed rental value from 2029, this logic shifts \u2014 direct amortization becomes more attractive again in many cases. Indirect amortization via Pillar 3a combines the debt interest deduction with tax-privileged retirement savings, and is often the most economical path under the current tax regime.<\/p>\n\n\n
Anyone who contributes more equity lowers the loan-to-value and thereby reduces the interest and amortization obligation. Anyone who instead keeps equity available for other investments accepts higher housing costs. This trade-off is individual \u2014 and belongs in sound financial planning before every property purchase.<\/p>\n\n\n
