Advantages of paying more of your mortgage while you know you won't continue to live there your whole life
It's pretty simple - the less money you owe the less interest you pay.  Paying down debt  gives a guaranteed return of the interest rate of the debt. So paying off your starter loan is equivalent to a 4% return.  That's not a bad return in the current environment so it makes sense to do it unless you can find an investment which you think is likely to pay significantly better. (Note this is a general answer, not Netherlands-specific.  There may be other considerations, around tax for example, which have to be factored into the calculation).
