I also thank the last writers for their opinions and will elaborate on a few things.
Does one need a house alone with a child? Nobody needs a house! Of course, an apartment is enough, but each of us has dreams in life and most will hopefully try to realize those dreams, no matter what kind they are. I want to be my own master, not have to take much/no consideration for neighbors (we both play wind instruments), etc... Whether the dreams come true is another matter. But it is hard for me to give up my dreams from the outset just because the marriage didn’t work out. I want to at least try, i.e. try to live my dream and only give up when it really can’t work. On the other hand, I am a big realist and when the hurdles become insurmountable, I will be reasonable. Promise ;-).
Now to my income situation. I’m already bracing myself. A13 minus health insurance currently nets me 3000€. Approximately 400€ in child maintenance and 200€ child benefit come in. Currently I pay 1250€ warm rent and save at least 1000€ monthly. We live well with the remaining money as two and I don’t feel like I’m missing out. The savings rate is also for the car and other things. From time to time we treat ourselves to something (e.g., kids’ skis, furniture, or similar). I drive an economical small car, only have a prepaid phone, and generally feel quite good with the available money. At the moment, we either go on vacation at the grandparents’ (who then spoil the single mom) or together with the grandparents in a holiday apartment within Germany.
When I read here that many plan the loan so that it can be paid by one person alone and you can still live, I wonder whether the majority of home buyers earn a lot more (i.e., one person) or if they are taking the risk? Equity will probably be the decisive point here. By the way, I would have used the private loan from the bank as equity and negotiated the rate with my parents, but maybe something is still possible there. I can’t assess that.
Used houses in need of renovation currently cost between 300,000 and 400,000 € around here plus renovation costs. So that is out of the question for me. Nice new apartments with garden areas cost about 350,000 € with all the disadvantages that an apartment has (and yes also the advantages).
For overview purposes, I will continue writing in the next post.
