Hello,
now I had to register myself after a long passive reading phase just to encourage you a bit.
Whether there are still costs waiting at the house or not can be better assessed by others than me.
But since I am in a similar situation: All the demands for "20-30%" equity come from times with higher interest rates. With your salary, you should also be able to manage the above-mentioned "2700€ incl. additional costs." At least if not one partner wants to stay completely at home because of a child, and the other also reduces to 70%. Calculate it the other way around: How much does the same living space of the same quality cost in rent? >1500€ cold rent I would estimate now. Additional costs come on top of that - and you should still put a few hundred euros aside for retirement savings. That is then not so much less than the 2700€. As long as the 30-year interest rates currently cost as much as the 15-year ones, the risk remains – but it is manageable.
Sure, it can also go wrong: (God forbid!) a disabled child, parents in need of care, an accident, burnout or divorce. But as long as the value of the property increases, you just have to slowly sell it and buy something smaller/more suitable. Especially because the conditions change then, e.g., one salary is lost = one has to commute less = save on childcare = living further out is okay = cheaper.
In this forum many people are building their absolute dream house (I am jealous ) and can under no circumstances imagine ever leaving it. But if you think a bit more pragmatically, you can simply sell a house, painful as it may be, if really a nasty combination of misfortunes hits you.
In that sense,
your new comrade BigFoot
