The transfer tax is the responsibility of the canton and varies significantly from one canton to another. The Canton of Aargau, like every Swiss canton, has its own tax law and specific rates for the transfer of real estate ownership.

Operational details
The mortgage in Switzerland
To access a mortgage, the bank evaluates the buyer's repayment capacity based on income, existing financial obligations, and the value of the property. The borrower must prove to have own funds (generally at least 20% of the purchase price) and that the mortgage burden is sustainable. A common rule in the Swiss market is that the monthly installments do not exceed 33% of the borrower's gross income.
Mortgage rates in Switzerland vary according to market conditions and decisions by the Swiss National Bank (SNB). Banks offer different solutions: fixed-rate mortgages (with terms from 2 to 15 years), variable-rate mortgages, or hybrid solutions. The choice depends on personal economic prospects and the general trend of interest rates in the market.
Taxation on buying and selling
In the purchase process, the buyer incurs various taxes and expenses:
Transfer tax: Levied by the Canton of Aargau upon transfer of ownership. This tax is calculated as a percentage of the purchase price; the rate and any deductions vary according to the cantonal tax law. Not all Swiss cantons apply this tax (some have abolished it), but the Canton of Aargau maintains it.
Notary fees: The notary charges a fee for drafting the deed of sale and the legal checks related to the transaction. The amount is regulated by cantonal law and depends on the value of the real estate transaction.
Registration tax: Levied by the Land Registry Office for the registration and entry of the deed in the public real estate registers.
Other taxes: In some cases, a stamp duty or other municipal taxes may apply, depending on local regulations.

Key points
Step-by-step procedure for purchasing
1. Financial capacity assessment: Before searching for a house, make a realistic assessment of what you can afford. Calculate your available own funds (minimum 20% of the estimated price), contact local banks to estimate what mortgage you could obtain, and verify the monthly burden of the installments based on your gross income to ensure it does not exceed 33%.
2. Search and offer: Search for properties in the Canton of Aargau market. Once you find a suitable property, negotiate the price with the seller and sign a preliminary offer or a non-binding promise of sale.
3. Mortgage instruction: Submit financial documentation to the bank (last 2-3 years of tax returns submitted to the canton, last 6 months of bank statements, recent pay slips). The bank performs an appraisal of the property through an appointed expert.
4. Notarial deed: Once the mortgage is confirmed by the bank, the parties appear before the notary to sign the authentic deed of sale. At this point, the buyer pays the own funds to the notary (or directly to the bank according to the agreed methods).
5. Registration: The notary transmits the authentic deed to the Land Registry Office of the Canton of Aargau for registration. The transfer of ownership becomes official and the new owner is registered in the public registers.
6. Mortgage disbursement: The bank disburses the mortgage funds and the seller receives the consideration (through the notary, who acts as a trustee throughout the transaction).
