Building a house without equity - is that possible?

Basically, it is possible. 100% financing. With that, you cover the costs of building the house and the land. However, there are costs that are not covered by the mortgage. These are ancillary purchase costs and furnishings such as kitchen, lamps, and other furniture. In addition, you need a buffer (cash) for unforeseen expenses. So, if you really have almost €0 on hand, the answer is: No. From €30,000 in cash, you can start considering it.

Besides the financial aspect, I can only advise against the project. You are still so young, have money in your hand for the first time. You have already splurged a bit on the cars, enjoy that first and take a nice trip. Maybe afterwards look for a 3-room apartment, but not a house right away. Also consider, if you go to a new development area, everyone there is 35+ and in a different phase of life. You would be the odd ones out. I wouldn’t do it.

Why now? At that age most people are still trying things out, want to see something of the country and its people, enjoy life, maybe change jobs a few times,...

A house is called real estate because it makes you immobile. It is a lifelong decision (unless you have enough money for a second and third house). Usually, you also plan a house in terms of content for your children, how does that look?

All completely independent of finances. Sure, you can have thought about all that, but there's too little input for me in the opening post.

Life sometimes writes strange stories. You shouldn't block yourself from all of them. It's not about disco and under-20 parties, but about a phase of life in which you gain so much experience and maturity.

Rented houses are great. All the freedoms of owning a home, but none of the obligations. We are currently living in our 2nd rented house and are now building our own. Each time (7 moves) the distance between living places was 100-800 km. I couldn't have imagined that at 19 either!

Basically, it's possible. 100% financing.

Without equity, it’s not even that. Here we are moving over 100%. There is also another thread running in parallel where someone requests the same with 4k€ income. I am happy to repeat myself. Financing this amount currently with 3800€ without equity is madness.
