I can understand Michael. We thought the same way at the beginning... we had a huge amount of money available (Double Income No Kids), and were looking for ways to invest the money sustainably. At some point, the idea of building came up. And quite quickly the sobering reality, which Michael is currently experiencing as well. Everything costs a hefty amount of money, and you wonder how others do it. Eventually, you have to decide whether to take the big risk or to leave it. For us, the decision was easier at 40% equity, but even so, you don’t take out over €200,000 in loans every day. We are sure, if nothing happens to us, the place will be ours in 20 years, and we will live rent-free until our children push us into a retirement home. Considering rent prices of almost €1000 cold, that’s not the worst choice. He now just has to work with the numbers and find out what he can afford. Then go away from internet prices to concrete offers, then compare construction service descriptions again and again and again. In 6 months you will have more clarity, and maybe find a provider who puts your needs in writing. Then you need about a year of good nerves and a good dose of dark humor, because no matter what you agree on, it always gets more expensive. Sometimes ridiculously little, but I can say, craftsmen always have something in their toolbox that can be charged later. Sometimes a ridiculous €10, but sometimes a nice four-digit amount, or like for us, twice five figures. And if you’re not prepared and depend on the bank being favourable to you, it gets tricky. Our net income is higher and equity much higher, yet a refinancing was refused for a much smaller loan amount. We were able to cut some things (garage, outdoor facilities) and pay the rest from our financial buffer. Building a house will probably become your most expensive investment after children. And you probably won’t get any return from a self-used property anyway.
