Because you asked in the other thread: we also took out a very large loan, but in the end we are paying "only" €200 more than we pay for our centrally located 2.5-room apartment in Munich. If you want to stay in the area (30 km around Munich), you have to reckon with rents of up to €3,000 cold per month in the long term – of course only if you want an apartment where each child has their own room and that is connected to public transport – and God forbid it might even have a garden. Of course, there are exceptions, but I don’t want to rely on getting lucky exactly when it’s needed.
Since we want an apartment with enough space and a garden and public transport connections and an opportunity to build arose (that was already the lucky break), we took the chance. The high loan is matched by a high value. If something doesn’t work out with the financing or if in 5 years we change completely and prefer to live in the forest or a job offer lures us away, we can rent or sell. I don’t worry about the concerns you have because there are enough "ways out" if this turns out to be the wrong decision. Since we discussed the options in detail once, the loan doesn’t feel like a burden.
The comparison of rental costs – loan amount certainly doesn’t work in all areas of Germany, but here it works very well. And if for you it turns out the same way as for us (which is the case if I look at your posts), then there’s absolutely no question what to do. Sign and go.
