Construction project and building permit feasible?

Even though I share the opinion that the numbers are much too optimistic, there still remains hope that things can actually be better in x years. But there are so many unknown variables regarding the new job, salary, children, etc., that really only waiting until the expected conditions have arrived helps. Fortunately, new equity capital should then also be available.

I know my comments on financial matters were unwelcome, but I don't mean it in a bad way at all. You have good prerequisites, just not until several years from now.
