At that age, I would first focus on increasing income. I experienced the same after my training. I earned about 1400 net and would have gotten an additional 5% per year (for a maximum of 3 years). Additionally, about 1.5% increase annually through collective bargaining agreements. Sounds nice, but it’s not really much.
Since I want to build a house and start a family, I completed a part-time degree. Now I am 29, have finished the degree, and consequently have a better job (within the same company). Now the net income is 2800 and we are starting the house construction this year. In the past 5 years, I was also able to save quite a bit, so that about 100,000 in equity has accumulated on the side.
My tip: Be patient, improve your income situation, and wait 3-5 years first to see what is possible. Good luck! :-)
