If you had a $200k mortgage, you would be paying $3,000 in just interest every month. And that's assuming you get the central bank rate, you don't. Probably looking more at like 20% for a loan an individual can actually get.
Good luck opening or expanding a business with rates like that too.
I looked up online calculators and it gives me 21.1% from sberbank. However it's just interest rate. And with additional fees it shows up to 24.4%. And you should bear in mind that actual terms tend to be worse. There is also a "military mortgage" which "starts from 18.9%", but it is not any better tbh.
Edit: apparently there are cheaper mortgages starting from 5% and 6% if you are buying "new property" that are labeled as "IT" and "family" ones. I don't know terms for those, but they are definitely not for everyone and they might have conditions which restrict those to a really small group of people. And you can't buy second hand property with those.
