Thanks in advance for your suggestions!
The property is not 10km away, but 17km. But that's still about 10km further out than where we currently live. There is already no gap anymore between the small town and the big city; they seamlessly merge into each other. The small town is also connected to the big city by tram, but you can easily spend about 45 minutes on it. But yes, the big city is growing. Everywhere farmland is being converted into building land, every gap is being closed.
15 years, because we just want to have it "gone" at some point. I would never plan for more than 20, and neither would my husband. The risk that something might happen is just too great, and you can't insure against everything. As tenants, in the worst case, you can move into an affordable 3-room social apartment until you are economically stable again. As homeowners, you make completely different commitments. If my children want to do a year abroad or study elsewhere or whatever, I don't want to have to stand there calculating whether I can afford it because I still have to pay 1200 plus additional costs for another 15 years. We also want to enjoy ourselves and not put all our income into a house. We studied for 7 years and had rather poorly paid jobs before, so we know what it’s like to have little money, and we simply don’t want that again. That’s why we prefer to plan this way rather than too tight.
We have already lived in this small town before. It’s not bad there, no. But is "not bad" the attribute that should fit the location of your own house? We are very uncertain about that. Of course, the advantages are obvious. Economically as well as for the children, the small town would be better. My husband grew up happily there, and we would never manage such a great and short financing without this property. We are also aware that all of this is "complaining on a high level." Others would surely wonder what our problem is and would be happy to have such a chance. For others, it would probably be a dream location anyway. But for us, as city people, it is not. The farther out in the countryside, the less we could imagine living there long-term. We really enjoy vacations in the countryside, but we wouldn’t consider living there all the time.
Developer: No, definitely not. The parents-in-law would certainly prefer to sell it themselves. They would gift it to us if we then used it ourselves. Otherwise, they could really use the money for their retirement themselves.
