I did. Could you explain where I am wrong? The apartment is that expensive because people can finance it. It's stupid, because an apartment is not magically worth more because people can finance more. Unfortunately that doesn't matter to people who need a place to live.
It's 3.86k if you want to own the property after 30 years. You don't have to. You might as well sell the house for 1.2mm after 30 years and just pay 12m per year on interests for 30 years.
