What is the minimum percentage of own funds required to buy a home in Switzerland?

There is no minimum federal legal constraint, but banks usually require 20% of the purchase value as equity. Lower percentages are possible, but will result in additional mortgage insurance (which increases costs) and perhaps higher interest rates. Check with your bank what minimum percentage they accept in your case.

How does the mortgage sustainability test work and what documents do I need to submit?

The sustainability test evaluates whether you can repay the mortgage with your gross income, considering all fixed expenses, taxes, insurance and home maintenance. Banks ask for: account statements, tax returns for the last 2-3 years, employment contract, list of existing debts, property appraisal. There is no single federal formula; each bank has its own internal prudential criteria.

Is the transfer tax the same in all Swiss cantons?

No, absolutely not. The transfer tax is a cantonal responsibility: each canton (including Lucerne) decides the rate independently. If you buy in Lucerne you will pay the Lucerne rate; if you buy in another canton, the rate will be different. You must check the cantonal administration rate before calculating the total budget. It is a non-negotiable cost.

Are notary fees a fixed percentage of the house price?

No. Notary fees vary according to the amount of the property and the cantonal rates of Lucerne. It is not a uniform national percentage. You can ask the notary for an estimate before signing the compromise, so you know exactly how much you will have to pay. It is an amount established by cantonal law, non-negotiable, but quantifiable in advance.

If the bank declines the mortgage after I sign the purchase promise, can I get out of the compromise without loss?

Usually yes, if the purchase promise contains a conditional dissolution clause to the loan. In this case, if the bank denies the mortgage, you can get out of the compromise without penalty. But you need to check the text of your contract: not all compromises have this protection. Have the document checked by a local lawyer before signing it.

An investment that requires complete planning

Those who decide to buy a house in the Canton of Lucerne face an operation that touches personal finances, cantonal taxation and federal administration simultaneously. It is not an isolated decision: every element — from the funds you can bring personally, to the bank's judgment on your repayment capacity, to the taxes that the Canton will apply — influences the final result.

The most common mistake is to consider the price of the property as the only cost. In fact, you must take into account at least three additional items: the total cost of the loan (interest during the amortization period), the transfer tax (paid to the Canton at the time of registration), notary and

Operational details

How own funds work in the Swiss market

There is no federal law that imposes a minimum percentage of own funds to buy a home in Switzerland. However, the market has developed a well-established practice: banks usually require at least 20% of the purchase value as equity. This rule is not random.

If you invest your 20%, the bank covers the remaining 80% through mortgage. From the bank's point of view, you have “already lost” 20% if the property goes down in value, so you are motivated to repay the mortgage. If, on the other hand, you wanted to buy with 10% or 5% of your own funds, the bank would accept but ask for additional mortgage insurance (an additional cost for you) to cover the higher risk.

In some special cases — for example, if you are young with a good stable income or if you have a long-term banking relationship — you can negotiate percentages of less than 20%, but you will have to expect higher interest rates and compulsory insurance.

# Sustainability Testing: How Banks Decide

This is the phase that determines whether you will receive the mortgage or not. It does not happen "automatically". When you apply for financing, the bank asks you:

Statements from the last few months (to verify that you manage your money well)
Income tax returns for the last 2-3 years (to ensure earnings stability)
Employment contract (to assess employment prospects)
List of
