To explain the current situation, perhaps one more point: the income has grown to this level over the past few years. I also started smaller back then. The equity was generated through the sale of a business interest, which could never have been reached with the (quite good) income. However, I see the equity more as a generational project and want to treat it as such.
I am aware that Munich is not the cheapest area. I notice that myself. However, I was brought up under somewhat different circumstances. That does not mean poor, but always frugal. And I do not want to completely throw overboard this path that I find appealing.
Regarding the matter of the condominium, one more remark. We have a condominium that my wife was gifted by her parents. But I also see that as tied assets and thus as a piggy bank. Especially since we currently see no way to meaningfully refinance any potential sales proceeds elsewhere.
Would there be interest if I post a preliminary cost calculation here? Or should I rather do that in the specific subforum? Many thanks for the comments and the really nice tone in an online forum. I know it differently...
