Key points at a glance
For residents of Onex (roughly 18’977 residents (postal code 1213)) (canton of Geneva), this local guide sums up what matters for "Mortgage and financing": aligning contracts, taxes and pension planning sensibly under Swiss law. Our approach is explanatory and neutral — it complements personal professional or tax advice but does not replace it.
In Switzerland some rules are cantonal (tax rates, deductions, allowances), others federal (LAMal, federal law). In Onex, your actual circumstances — renting or owning, employment status, household size, vehicles, cross-border income — therefore shape risk and priorities far more than the postal code. The nearest municipalities — Confignon (1 km), Lancy (1 km), Vernier (2 km) — each have their own local page as well. The sections below list the key points to check.

Mortgage and financing in Onex: rate, affordability, protection
Anyone buying or renewing a mortgage in Onex operates within the usual framework: equity (at least 20%, part of it "hard" equity), an affordability calculation with a notional rate and mandatory amortisation of the second mortgage. Whether a fixed-rate mortgage, SARON or a combination suits you better depends on rate expectations, risk capacity and planning horizon.
Financing goes hand in hand with protection: depending on the situation, lenders require or recommend building insurance, loss-of-earnings or death-risk cover. For tax, mortgage interest is generally deductible — and the trade-off between direct amortisation and indirect amortisation via pillar 3a should be worked out over ten to fifteen years.
Work through before signing
- Affordability if rates rise (notional interest rate).

- Direct vs. indirect amortisation (pillar 3a) and the tax effect.
