Hi there,
When applying for personal loans from Swiss banks, the intended use of the loan has little effect on loan approval or the interest rates you get. Your creditworthiness is the main factor in determining the interest rate you get.
You can find the best deals on personal loans using the moneyland.ch personal loan comparison.
Note that the rates shown are guide rates indicating the highest and lowest interest rates available. The exact rate you receive will depend on your creditworthiness. The better your creditworthiness, the lower the interest rates you will get.
Best regards from Moneyguru
