ᐅ Building a House at 21 Years Old... Too Young?

I’m not quite sure how to start this thread properly. I hope I’m in the right section. I’ll just begin.

I’m still quite young, but I have always decided that only a prefabricated house is an option for me. My interest is not just for a few months, but rather spans several years, as I am planning my future with a long-term perspective. I want to build early because I want to pay off the house as soon as possible. I have already visited several well-known prefab house companies and have been really impressed. Since we don’t live far from a company headquarters (Frankenberg), I have also visited model homes several times.

Having a steady job with a regular income is, of course, a requirement that I meet.
I already have a plot of land, so I don’t have to worry about that.
Equity will also be available.

My question is simply whether there are other young homebuilders here who might share their experiences with me. Perhaps there are also recommendations on whether my decision to take on such a commitment so early is the right one or not.

Thanks in advance for any help.
