What is the minimum percentage of equity required to access a mortgage loan?

The minimum required by credit institutions is generally 20% of the purchase price of the property. However, many institutions require 25-30% to obtain favorable conditions and avoid additional mortgage insurance. The exact percentage depends on the credit policy of the institution and the personal conditions of the borrower (income, assets, credit history).

What is pass-through tax and who determines it?

Transfer tax (or “freight tax”) is a tax levied on the transfer of real property. It is the exclusive responsibility of the cantons, so each canton has its own legislation. The rate varies depending on the canton and municipality, and is calculated on the value of the property at the time of transfer. The notary applies this tax and pays it to the competent cantonal and municipal authorities.

What are the typical ancillary costs in addition to the purchase price and mortgage?

Ancillary costs include: notary fees (based on the value of the property), registration fee in the cantonal land register, transfer tax (cantonal and municipal), valuation fee requested by the bank, compulsory insurance (owner's civil liability, fire). Overall, these costs typically represent 5-8% of the purchase price, varying according to the specific cantonal legislation.

How long does the purchase process take from the signing of the preliminary to the final registration?

The average duration is between 3 and 6 months. The time depends on the speed of approval of the loan by the bank, the availability of the notary and the processing time of the cantonal land registry office. In some cases, the process may be faster (2 months); in others, if administrative complications arise, it may take longer than 6 months.

How to assess the sustainability of a mortgage?

Sustainability is assessed by comparing the monthly installment of the mortgage (principal + interest) with the monthly gross income. A common rule is that the installment does not exceed about one-third of gross income. However, each institution has its own criteria. It is advisable to consult calculation tools to simulate different price, interest rate and duration scenarios, and contact multiple institutions to compare valuations before formally committing.

Operational details

Cantonal taxes and transfer costs

Switzerland operates a tax system divided into three levels — federal, cantonal and municipal. The transfer tax (transfer of real estate ownership) is the exclusive responsibility of the cantons, for which the Inner Appenzell Canton has its own specific legislation. This tax applies to the transfer of ownership and varies significantly depending on the cantonal legislation.

At the federal level, the Federal Administration (via AFC/ESTV) manages the Federal Direct Tax (IFD) and Value Added Tax (VAT), while cantonal and municipal administrations independently determine rates on inheritances, donations and real estate transfers. Appenzello Interno has set specific rates. The administrative procedure requires the notary to communicate the transfer to the cantonal land register, which informs the local tax administration for the application of the tax.

Notary fees and land registration

The notary is a mandatory figure in Switzerland to authenticate the sales contract and guarantee the legal validity of the transfer. Notary fees are not fixed by a general federal law, but are set by cantonal rates. In the Inner Appenzell Canton, the notary applies a rate based on the value of the property, according to scales published by the cantonal professional associations.

The land register is managed at cantonal level and is the official register of

Practical Buyer's Checklist

Before starting negotiations in the Canton of Appenzell Innerrhoden, it is essential to verify and plan the following:

1. Availability of own funds: Ensure you have at least 20% of the estimated purchase price as equity. Many institutions require 25-30% for competitive offers.

2. Mortgage affordability assessment: Contact one or more credit institutions for preliminary advice on the maximum financing available based on your income.

3. Verification of land registry status: Obtain information from the cantonal land registry office to check the legal status and existing mortgage encumbrances of the property.

4. Preliminary meeting with a notary: Book a consultation (generally free of charge) to receive an estimate of notary and registration costs.

5. Budget for ancillary costs: Allocate funds for property transfer taxes, registration fees, and mandatory property insurance (civil liability, fire).

Procedure from preliminary agreement to registration

Once the property is identified, the buyer and seller enter into a preliminary contract (promise of sale) before a notary. This document binds the parties to the economic terms and deadlines. The preliminary contract is not yet entered into the land registry, but it constitutes the first legal commitment.

Subsequently, the buyer finalizes the mortgage loan with the credit institution: the bank formally communicates the approval and its amount, linking the mortgage guarantee to the specific property. At this point, the final deed of sale is drafted by the notary and signed by both parties. The notary authenticates the document and immediately submits the registration application to the cantonal land registry.
