If the parents support your start, that's great. The possibility of building real estate wealth across generations is something many families surely wish for, and in the future it will probably be even more important. Otherwise, completing a proper education - top! If the bank also gives the thumbs up, then it will work out.
You could consider setting the fixed interest period to 20 years or more. The rate won't be affected that much, and after 10 years you have a special right of termination anyway, afaik. If the interest rates are lower, refinancing could be worthwhile. If they are higher, you did everything right.
Are 1.5% instead of 2% repayment and 20 years fixed interest perhaps worth considering? Having debt is not that bad if you can afford it. Inflation helps.
