I looked at the costs, and frankly, too much money will be spent on various consultations and 'conversations', and it seems to me unjustified to take a loan + pay interest for such things, while the whole process has not moved forward much.

I assume that you can provide some clear guarantees for this money, some real estate that you own or similar. This should not be a problem if you already have a safe income that will cover the repayment of the loan investment.

btw. Why do you decide on Switzerland, one of the most expensive countries, if the location is not your primary concern? It seems like an unnecessary waste of investors' money, for a longer-term investment, it is necessary to demonstrate a much more rational spending of money.
